Know Your Storage Limits and Plans
Your OneDrive for Business storage depends on your Microsoft 365 plan. Different plans give you different amounts of space, and understanding which plan you have matters because it shapes what you can do next.
Business Basic gives you 1 terabyte of storage. This plan costs $6 per user per month and includes email, calendar, and basic Office apps online. One terabyte equals 1,000 gigabytes, which sounds like a lot until you store large video files or many design documents. Most small teams find this amount works fine for regular business files.
Business Standard also includes 1 terabyte of storage and costs $12.50 per user per month. This plan includes desktop versions of Word, Excel, and PowerPoint that you can install on your computer. The storage amount stays the same as Business Basic, so upgrading for more space means you need a different option. Teams that need desktop software often choose this plan anyway because they need those programs for their work.
Business Premium includes 1 terabyte of storage and costs $20 per user per month. This plan adds advanced business tools like scheduling, analytics, and better team management features. Again, storage stays at 1 terabyte, so the plan you pick should match the software you need, not just the storage you want. Your storage amount does not increase simply because you pay more for your plan.
Microsoft 365 Enterprise plans offer similar storage with slightly different costs and features. Enterprise E3 costs about $20 per month and gives you 1 terabyte of storage for your OneDrive. Enterprise E5 costs about $35 per month and also provides 1 terabyte. Both include premium security and advanced compliance tools that small businesses don’t usually need.
The key fact is this: Almost all Microsoft 365 plans include 1 terabyte of base storage. You get the same 1 terabyte whether you choose Business Basic or Business Premium. The difference is what programs and tools come with each plan, not the storage space. This means your plan choice should depend on what software you need, not how much cloud space you want.
Check Your Storage Right Now
Before you request more storage, you need to know how much space you actually use. This takes just two minutes and shows you exactly where your problem sits. Checking your storage regularly helps you stay aware and plan ahead for future needs.
Open OneDrive on the web by visiting onedrive.live.com and signing in with your work account. Once you log in, look at the top left corner of your screen where you will see a blue circle with your name or initials. Click on that circle and select “Settings” from the menu that drops down. This opens your account settings where you can find storage information.
In the Settings menu, find the option that says “Storage” and click on it. You will see a detailed breakdown of your storage usage displayed on your screen. The screen shows you a large bar graph that displays how much storage you use and how much you have left remaining. You also see exact numbers that tell you how many gigabytes you consume in total. Below that visual bar, the screen lists files and folders from largest to smallest, so you can spot which items take up the most space.
If you use Outlook for email, you can also check storage information from your email account settings. Open your Outlook account and click the gear icon in the top right corner. Choose “View all Outlook settings” and then go to “Storage” to see that information. This shows the same information and helps you see if your email attachments take up most of your space.
| What You See | What It Means |
|---|---|
| The blue bar at the top | How much of your 1 terabyte you actually use |
| The list below the bar | Your biggest files and folders listed heaviest first |
| The percentage number | What portion of your total storage is full |
Request More Storage Through Microsoft
When you hit your limit, you have options to get more space without waiting weeks. The fastest way is to ask Microsoft directly through your account settings on OneDrive. This process takes only a few minutes and your storage expands almost immediately.
Go to your OneDrive storage page and look for the button that says “Buy more storage.” This button appears when you use most of your space and clouds your view. Click it and you will see options to purchase additional storage amounts. Microsoft sells storage in specific amounts including 100 gigabytes for about $2 per month or 1 terabyte for about $10 per month.
When you buy extra storage, it adds to your existing 1 terabyte amount. If you purchase the 1 terabyte option, you now have 2 terabytes total space. If you buy the 100 gigabyte option, you have 1.1 terabytes available for your files. The purchase happens right away, and your storage increases within minutes of completing the transaction.
You can also upgrade your entire Microsoft 365 plan instead of just buying extra storage alone. Some people find this option better because upgrading gives them new software and tools along with extra space. If you move from Business Basic to Business Premium, you get better apps plus the ability to buy additional storage on top of your 1 terabyte. This approach makes sense if you need both more software and more storage at the same time.
The purchase is simple and requires just a credit card number. Microsoft charges your card every month until you cancel the storage plan subscription. You can stop the purchase anytime by going back to the same settings page and clicking the option to cancel. Remember that canceling stops future charges but you keep the storage you paid for until your subscription period ends.
What Admins Can Do to Give Users Storage
If you manage a team or work in IT, you have more powerful options to increase storage for your users. Admins can increase storage without asking users to pay extra money out of their personal accounts. This approach saves money for your team and keeps things simple for your employees.
Admins access the Microsoft 365 admin center by going to admin.microsoft.com and signing in with admin credentials. Once you log in, click on “Users” in the left menu and then select “Active users.” This shows a list of all the people in your organization with Microsoft 365 accounts. You can view each person’s current storage usage and limits from this list.
Find the user who needs more storage and click their name to open their account details. In the user details panel that opens, look for the section labeled “OneDrive storage” on the page. This section shows how much storage that person currently uses and their current limit amount. You see a dropdown menu that lets you change their storage limit without needing to involve the user.
| Step | Action |
|---|---|
| Open the admin center | Go to admin.microsoft.com |
| Find the user | Look in the Active users list |
| Select storage option | Click OneDrive storage section |
| Change the limit | Use the dropdown menu |
The admin can increase storage from 1 terabyte up to 5 terabytes per person. This increase costs the company nothing extra because it comes from your organization’s total storage pool. Microsoft gives every Microsoft 365 organization a shared storage pool that grows as you add more users to your account. If your company has 100 users, you get a large pool that lets you give some users extra space.
Admins can also set storage limits for groups or teams rather than individual people. If you have a SharePoint team site used by multiple people, you can increase the storage for that site instead of individual users. This works well when an entire team needs more space for shared projects and collaboration. Go to the SharePoint admin center, find the site, and change its storage quota using the same dropdown method.
Setting storage limits for users takes about 30 seconds per person in most cases. If you manage a large organization with hundreds of users, you can use PowerShell scripts to change storage limits for many users at once. This saves significant time when multiple people need more space all at the same time.
Three Real Scenarios You Will Face
Scenario One: The Designer Who Works With Large Files
Maya works as a graphic designer at a marketing company and creates content daily. She creates videos, design mockups, and photo galleries that use massive amounts of storage space. After three months, her OneDrive fills up completely and she cannot save new projects anymore. She needs a solution fast because her clients are waiting for their work to be completed.
Maya checks her storage and sees she uses 980 gigabytes out of 1 terabyte total. Most of her space comes from video files and high-resolution images that clients require. She has two options: delete old files or buy more storage immediately. Deleting files means losing her portfolio, so she clicks “Buy more storage” and purchases 1 terabyte for $10 per month. Her storage jumps to 2 terabytes and her projects save without problems again.
| Maya’s Choice | Maya’s Outcome |
|---|---|
| Buy more storage | Gets 2 terabytes total and keeps her old files safe |
| Delete old files | Loses portfolio examples and future income potential |
Scenario Two: The Team That Shares Everything
A sales team at an insurance company shares documents in OneDrive for their work. They have price lists, client contracts, training materials, and past proposals stored together. The team’s shared folder uses 1.2 terabytes, which exceeds the original limit. Work slows down because people cannot upload new files to the shared space.
The IT admin logs into the admin center and increases the team site storage from 1 terabyte to 2 terabytes. This takes 45 seconds and costs the company nothing extra for the increase. The team can now upload and access everything they need without any problems. The admin also sets up a cleanup schedule to delete old proposals every six months to prevent this problem in the future.
| Team’s Problem | Team’s Solution |
|---|---|
| Shared folder exceeds 1 terabyte limit | Admin increases site to 2 terabytes in 45 seconds |
Scenario Three: The Remote Worker On A Budget
James works from home for a software company and receives a Business Basic plan. This plan includes 1 terabyte of storage, but he uses it for work files and personal storage. He stores work files, personal backups, and family photos all mixed together. After a year, his storage fills to 95 percent and he worries about paying extra money.
James first cleans up his files by deleting duplicate downloads and old versions of documents he has saved. He removes 150 gigabytes of unnecessary data from his storage. Next, he moves personal photos to a separate external hard drive to free up more space. These actions free up 350 gigabytes and bring him down to 35 percent usage. James avoids paying extra money by organizing what he already has and making smart choices.
| James’s Action | James’s Result |
|---|---|
| Delete duplicates and old versions | Free 150 gigabytes |
| Move personal photos to external drive | Free 350 gigabytes more |
The Best Ways to Use Your Storage
Once you have more storage, use it wisely so you do not fill it up again in a few months. Smart storage habits help you keep everything organized and find files quickly. Good habits today prevent expensive storage purchases tomorrow.
Separate work files from personal files to keep things clean. Keep only work documents, spreadsheets, and presentations in your OneDrive for Business account. Store personal photos, music, and videos on a personal OneDrive or external drive instead. This separation makes work faster because you see only business files when you search for what you need.
Use OneDrive sync to keep files on your computer as well as the cloud. The sync feature downloads your OneDrive files to a folder on your computer automatically. You can access files even when the internet goes down or is unavailable. The files also back up automatically to the cloud so you never lose them. When you edit a file, it updates everywhere at once across all your devices.
Delete old versions of files to save space regularly. When you edit a document, OneDrive keeps old versions automatically without you doing anything. You can access these old copies anytime by right-clicking the file and selecting “Version history.” After you confirm you do not need old versions, delete them. Each file can have hundreds of old versions that pile up space over time without you knowing.
Move large files to a shared team folder if you work in a group. If you store a 2 gigabyte video that multiple people need, put it in a team site instead of your personal OneDrive. This counts toward the team’s storage, not your personal limit. Sharing space this way helps everyone stay under their individual limits and reduces confusion.
Do not backup personal devices to OneDrive for Business accounts. Your work account is not meant to store personal computer backups of your home devices. These backups are huge and can fill your storage in days without warning. Use external hard drives or personal OneDrive for backups instead of your work account.
Mistakes That Waste Storage Space
Many people accidentally fill their storage with things they do not need. Knowing what to avoid saves you money and keeps your account running smoothly. Understanding common mistakes helps you make better decisions about your files.
| Mistake | Why It Wastes Space |
|---|---|
| Keeping every email attachment | Attachments pile up fast and duplicate in folders |
| Storing personal backup files | Computer backups are huge and grow daily |
| Keeping every old version of files | Documents auto-save versions automatically every time |
| Saving videos to OneDrive | Video files are massive, especially HD video |
| Mistake | Why It Wastes Space |
|---|---|
| Copying files instead of moving them | The same file exists in two places |
| Not using sync properly | Files stay in cloud only and hard to manage |
| Ignoring your storage meter | You do not see the problem until too late |
| Storing duplicate downloads | Same files downloaded multiple times pile up |
Do’s and Don’ts for Storage Success
Do’s:
- Do check your storage monthly to catch problems early before you hit your limit
- Do buy extra storage when you need it instead of deleting important files that matter
- Do organize files into folders by project so you find files fast and spot what takes space
- Do use team sites for shared documents when many people need the same files for work
- Do delete old versions of files after you confirm you do not need them anymore
Don’ts:
- Do not store personal backups on work OneDrive because they grow huge and crowd out work files

- Do not mix work and personal files together because it makes your account messy and confusing
- Do not ignore storage warnings when Microsoft tells you that you are running low immediately
- Do not assume you need the most expensive plan when a simple storage purchase might solve it

What You Should Know About Storage Limits
Microsoft has rules about how much storage you can have and what happens next. These rules protect the system for everyone but can affect your work. Understanding these limits helps you plan ahead and avoid problems.
Individual user storage limits go up to 5 terabytes if an admin increases them. This is more than most people ever need for their work. The 5 terabyte limit exists because Microsoft needs to keep the system running smoothly. If everyone had unlimited storage, the system would slow down for millions of users.
When you hit your storage limit, you cannot upload new files. You also cannot sync files to your computer or edit documents in the web version of Office. This is a hard stop, not a warning message. Your work halts completely until you either delete files or buy more storage.
Your OneDrive does not delete files automatically when you hit your limit. You must manually delete them or buy extra storage immediately. Microsoft gives you 93 days after deleting a file to recover it from the recycle bin. After 93 days, the file is gone forever.
OneDrive and email storage are completely separate. Your 1 terabyte OneDrive does not share space with your Outlook mailbox. Outlook has its own 50 gigabyte limit, and you can buy more email storage separately. Many people think these are connected when they are actually independent.
Shared team sites have different storage rules than personal OneDrive accounts. A team site can have larger storage amounts than a personal account. However, the entire team shares this storage, so one person’s large files affect what everyone else can store. This requires planning and communication with your team about what gets stored where.
Storage purchases are permanent until you cancel them. If you buy 1 terabyte of extra storage for $10 per month, you will be charged every month. You must go back to your settings and click “Cancel” to stop the charges. If you forget to cancel, the charges continue even if you do not use the storage.
FAQs
Can I share my extra storage with other people?
No. Your purchased storage applies only to your account. Team members have separate storage limits. However, if an admin increases your limit from the admin center, it comes from shared company storage.
What happens if I delete a file by accident?
Yes, you can recover it. Deleted files go to your recycle bin for 93 days. Open OneDrive, click “Recycle bin” on the left, find your file, right-click it, and select “Restore.” After 93 days, it is gone forever.
Does email take up my OneDrive storage?
No. Email and OneDrive storage are separate. Your email has its own 50 gigabyte limit. Full mailboxes do not affect your OneDrive, and full OneDrive does not affect email.
Can I downgrade my plan and keep extra storage?
No. If you buy extra storage and later downgrade your Microsoft 365 plan, you lose the extra storage. Your account goes back to the base limit for your new plan. Any files over the new limit become inaccessible until you delete them.
How long does it take to add storage?
Instantly. When you purchase extra storage or an admin increases your limit, it takes effect within minutes. You can start using the new space right away without waiting.
Will my files stay safe if I buy more storage?
Yes. Buying storage does not change how Microsoft protects your files. Your files are encrypted and backed up the same way no matter how much storage you purchase.
Can I buy storage for someone else?
No. You can only buy storage for your own account. Admins must increase storage for other users by using the admin center. Other users can purchase their own storage if they want.
What is the difference between synced files and uploaded files?
No difference. Synced files and uploaded files count the same toward your storage limit. Whether you upload files through the web or sync them to your computer, they use the same amount of space.
Do I lose my extra storage if I change jobs?
Yes. If you leave your company, your account is deleted and so is your extra storage purchase. Your work account and everything in it belongs to your employer, not to you.
Can I access my storage from my phone?
Yes. The OneDrive mobile app lets you view files and manage storage on your phone. Open the app, go to settings, and select “Storage” to see your usage. You can buy extra storage from the app too.
What if my team needs more storage but the admin says no?
Work with your admin on a plan. Admins control company storage based on budget and needs. If your team genuinely needs more space, document why and ask your admin to increase your limit. Show them what files you store and why they matter.
Is it cheaper to buy extra storage or upgrade my plan?
Buying storage is usually cheaper. Extra storage costs about $10 per month per terabyte. Upgrading to a higher Microsoft 365 plan might cost $5 to $15 more per month but includes new software. Buy storage if you need only more space, or upgrade if you also need better tools.
Can an admin increase storage beyond 5 terabytes?
Yes, but with conditions. If your organization has five or more users and someone is at 90 percent of their 5 terabyte limit, you can request additional storage from Microsoft support. This requires meeting specific requirements and approval from Microsoft.
Does OneDrive sync slow down my computer?
Not usually. OneDrive sync runs in the background without slowing your system significantly. You can adjust sync settings to sync only the folders you need. This helps save computer storage and reduces any performance impact.
What if I hit my storage limit during a work emergency?
Buy storage immediately. You can purchase extra storage in minutes from your OneDrive settings. This gets you access back right away without waiting. After the emergency passes, you can decide if you want to keep the extra storage.
Are there tax implications when I buy OneDrive storage?
Possibly. If your company buys storage for work use, it is a business expense. If you personally buy storage with your own money, it might be tax deductible if you use it for business purposes. Talk to your accountant about your specific situation.
