how to fix server storage quota exceeded?

Question

Have tried everything mentioned in numerous searches, but still get error Server Storage Quota Exceeded.

Answer 1

Hi,

Thank you for sharing your question. I know how disruptive quota errors can be, especially when you’re certain you still have space available and your work depends on saving or syncing files normally.

This error typically appears when the service you’re saving to such as OneDrive, SharePoint, or your Exchange mailbox believes you have reached its assigned storage limit, even if the available space looks sufficient. Microsoft guidance explains that quota overages can occur when hidden data such as recycle bin contents, shared library limits, or cached storage usage push you over your actual server‑side quota, leading Office apps to block saves. Reviewing your true storage usage in the Microsoft account dashboard and checking mailbox or SharePoint quotas helps identify which service is full, and freeing space or increasing the quota resolves the issue.  In some OneDrive‑related cases, logging out of Office apps, re‑adding OneDrive as a service, or resetting the OneDrive client can correct sync or quota‑related inconsistencies, especially when the error occurs only in shared folders or when Office thinks your storage is full despite ample space.

When you see the error, are you working in a OneDrive folder, a shared library, Outlook/Exchange, or SharePoint and have you recently checked your actual storage usage in your Microsoft storage dashboard?

If you can tell me which service you’re saving to and whether it’s shared or personal storage, I can give you a precise, Learn‑aligned set of steps to fix the quota issue quickly.

 

I hope this helps.

 

Best Regards,

To resolve the "Server Storage Quota Exceeded" error, you can consider the following steps:

1. Check Mailbox Quota: If you are using Exchange Server, ensure that your mailbox is not exceeding its quota. You can check the current size and quota size of your mailbox using the following PowerShell cmdlet:

      Get-MailboxStatistics -Identity <User> | FL displayname,totalitemsize
   

2. Increase Mailbox Quota: If your mailbox is over the quota, you can temporarily increase the mailbox quota using the following cmdlet (replace <User> with the actual user identity):

      Set-Mailbox -Identity <User> -ProhibitSendReceiveQuota 2.1GB -ProhibitSendQuota 2.1GB -IssueWarningQuota 2.1GB
   

   If you are using the default quota from the database, disable it with:

      Set-Mailbox -Identity <User> -UseDatabaseQuotaDefaults $false
   

3. Delete Unnecessary Items: Review your mailbox and delete items that are no longer needed to free up space.
4. Enable Archive Mailbox: If applicable, enable the archive mailbox and turn on the auto-expanding archiving feature to manage storage better.
5. Check SharePoint Storage: If the issue is related to SharePoint, ensure that your organization has enough storage based on the number of licenses. You may need to purchase additional storage or delete unnecessary content.

Following these steps should help you resolve the storage quota issue.
