OneDrive in Microsoft 365 Developer Program limited to 10 GB instead of 1 TB

Question

Hello,

I am using a Microsoft 365 Developer Program tenant and I am experiencing an unexpected OneDrive storage quota issue with one of my user accounts.

The account receives daily emails stating:

Your OneDrive is out of storage space

and

You've reached your 10 GB storage limit

In the OneDrive storage section, I can see:

• 49.8 GB used
• 10 GB storage limit
• 498% usage

However, I expected this account to have access to 1 TB of OneDrive storage as part of my Microsoft 365 Developer Program environment.

Additional information

• The user account was created after the tenant was initially set up.
• The account is able to access OneDrive normally.
• Large download operations through the web interface often fail after the preparation stage.
• I have already reviewed OneDrive and SharePoint troubleshooting documentation.
• I continue to receive daily storage warning emails.Hello, I am using a Microsoft 365 Developer Program tenant and I am experiencing an unexpected OneDrive storage quota issue with one of my user accounts. The account receives daily emails stating:

  Questions
  1. Why is this user account limited to 10 GB instead of 1 TB?
  2. Could this be related to licensing, SharePoint configuration, or OneDrive quota settings?
  3. Are there specific locations in the Microsoft 365 Admin Center or SharePoint Admin Center that I should check?
  4. Has anyone experienced the same behavior in a Microsoft 365 Developer Program tenant?
  Any guidance would be greatly appreciated. Thank you.

Hi Hugo,

Thank you for reaching out regarding the OneDrive storage limit on one of the user accounts in your Microsoft 365 Developer Program tenant.

This behavior usually occurs because the OneDrive for this account was assigned a lower storage quota when it was created, either because the user did not have a license that includes OneDrive at that time or because the tenant default storage setting was lower than 1 TB.

To bring the account back to the expected 1 TB limit, please follow the steps below:

1/ Verify the user license in the Microsoft 365 admin center

• Sign in to the Microsoft 365 admin center and go to Users > Active users, then select the affected user.
• Open the Licenses and apps tab and confirm that the Microsoft 365 E5 (Developer) license is assigned.
• After that, expand Apps and make sure that SharePoint (Plan 2) and OneDrive are both enabled, then select Save changes.
• Reference: Assign Microsoft 365 licenses to users

2/ Check the default OneDrive storage limit in the SharePoint admin center

• Open the SharePoint admin center and go to Settings, then select OneDrive Storage limit.
• Set the default storage limit to 1024 GB and select Save.
• However, please note that this setting only applies to newly created OneDrive accounts. Therefore, the existing account also needs the change in Step 3.
• Reference: Set the default storage space for OneDrive users

3/ Increase the storage limit for this specific user

• Return to the Microsoft 365 admin center
• Go to Users > Active users, then select the affected user.
• Open the OneDrive tab and select Edit under Storage used.
• Enter 1024 GB as the maximum storage and select Save.
  • Reference: Change a specific user's OneDrive storage space

Once these changes are applied, please allow up to 24 hours for the new storage limit to appear in OneDrive. After the quota updates, the daily warning emails will stop, and large downloads from the web interface should work normally again.

If the account still shows a 10 GB limit after completing these steps, please reply to this email with a screenshot of the user's Licenses and apps tab and OneDrive tab, and I will be glad to assist you further.

Kind regards.

Answer 2

This is expected behavior for a Microsoft 365 Developer Program tenant.

For Microsoft 365 E5 developer subscriptions, the documented storage expectations are:

• 300 GB pooled tenant storage for developer-only tenants
• 0 GB additional SharePoint storage contributed by the Developer SKU in mixed-license tenants
• 10 GB OneDrive storage per user for users licensed with the Developer SKU

That means the 10 GB limit is license-based, not a normal 1 TB commercial OneDrive entitlement. If this user is licensed only with the Developer SKU, the OneDrive quota shown is aligned with that license.

Why the account is now read-only or warning repeatedly:

• OneDrive enforces per-user quotas based on license entitlements.
• If usage exceeds the licensed quota, the OneDrive site can become read-only.
• When over quota, users can't upload, edit, or sync new files. Existing files remain accessible but read-only.
• If the account stays over quota, OneDrive can eventually be frozen, and after a longer period files may be deleted.

For the specific numbers shown:

• 49.8 GB used against a 10 GB limit means the account is far above its licensed quota.
• This can happen if the quota was previously higher, or if quota enforcement was recalculated to match the current license.

What to check:

1. Confirm the assigned license for that user in the Microsoft 365 admin center.
   • If the user only has the Microsoft 365 E5 Developer license, 10 GB per user is the expected OneDrive limit.
2. Check the user’s OneDrive quota in SharePoint/OneDrive admin settings.
   • If a higher quota was configured previously, current enforcement can still reduce the effective limit back to the licensed entitlement.
3. If quota changes do not behave as expected, a Microsoft 365 administrator can run the OneDrive storage quota diagnostic from the Microsoft 365 admin center by selecting Run Tests.
   • This diagnostic is not available for GCC High, DoD, Microsoft 365 operated by 21Vianet, and Microsoft 365 Education.
4. Reduce storage usage below 10 GB if the license cannot be changed.
   • Delete or move unnecessary files.
   • Empty the OneDrive recycle bin, because deleted files can continue to count until permanently removed.
   • After usage drops below quota, allow time for SharePoint Online to reevaluate the site, then verify upload and edit access again.

Direct answers to the questions:

• Why 10 GB instead of 1 TB? Because Microsoft 365 Developer Program users on the Developer SKU have a documented 10 GB per-user OneDrive limit.
• Could this be licensing, SharePoint configuration, or quota settings? Primarily licensing entitlement. SharePoint/OneDrive quota settings can exist, but enforcement aligns the user’s maximum OneDrive storage with the license entitlement.
• What admin locations should be checked? The user’s assigned license in the Microsoft 365 admin center, and the OneDrive storage/quota settings plus diagnostics available through the Microsoft 365 admin center and SharePoint admin controls.
• Has this happened to others? Yes. Similar cases in Microsoft Q&A report the same behavior in Microsoft 365 Developer Program tenants, with OneDrive locked at 10 GB for Developer SKU users.
