Email Storage Not Updating

I deleted some items so that my Microsoft storage would be under 5GB (it's at 3.8 GB according to OneDrive), but I still can't receive emails because Outlook thinks I'm still at 5.6 GB/5 GB even though I'm actually at 3.8 (the bar doesn't reach the end). It's been three days since I deleted the files. What should I do?

 

  • It sounds like Outlook’s storage calculation hasn't updated properly even after you've deleted files. Here are some steps to help resolve this issue:

    1. Check the Deleted Items and Recoverable Items Folder

    • When you delete emails, they move to the Deleted Items folder first.
    • To free up space, permanently delete them:
      • In Outlook Web App (OWA), go to Deleted Items.
      • Click Empty folder to permanently remove the emails.
      • Next, go to Recoverable Items (Shift+Delete items go here).
        • In Outlook Web, navigate to Deleted Items.
        • Look for "Recover deleted items" (a link above the list).
        • Select and Permanently delete any remaining items.

     

    2. Check Other Large Items (Calendar, Drafts, Sent)

    • Attachments in Sent Items and Drafts can take up space.
    • Go to these folders and delete large emails manually.


    3. Clear Local Cache (if using Outlook Desktop)


    If the issue persists, Outlook's local cache may not be syncing correctly.

    • For Windows:
      • Close Outlook.
      • Navigate to C:\Users\YourUsername\AppData\Local\Microsoft\Outlook
      • Delete the .ost file (your account will re-sync when reopened).
      • Restart Outlook.
    • For Mac:
      • Open Outlook.
      • Go to Preferences > Accounts.
      • Select your account and choose "Remove".
      • Re-add the account to refresh storage.
