Over storage isue

Question

Hi Microsoft,

I'm encountering to a message "You're over your storage limit..." as below.

However my current storage is only 169G/1TB. Could you please help to check and fix?

Thanks.

Answer 1

Your mailbox view confirms there are no large emails, so this is a quota calculation error on Microsoft’s side. Go to https://account.microsoft.com/services, open the Outlook storage page, then select Reduce mailbox size to force a refresh. Sign out of Outlook.com, clear your browser cache, then sign in again. Let me know how it goes.

Answer 2

Hello. Thanks for sharing the screenshot.

This message appears when Outlook storage, not OneDrive, is over quota. Microsoft now counts Outlook email storage separately from your OneDrive files.

Go to https://account.microsoft.com/services, open the Outlook storage page, and check the “Attachments” and “Mailbox” sections. If Outlook shows over quota, delete large emails, empty Deleted Items, then force a refresh by signing out and signing in again. This is a recent storage update where Outlook reaches its own limit even if OneDrive has space.
