When deleted messages in a Hotmail/Outlook.com account keep coming back, the usual causes are:
- Deleted items not being emptied
- Very large delete operations timing out
- Messages being restored from the Recoverable items store
Use these steps in Outlook.com (web) to fully remove them and stop them reappearing:
- Delete from the folder again
- Go to the folder (Inbox, Junk, etc.).
- Select the check box above the message list.
- In the reading pane, select Empty folder.
- All items move to Deleted Items.
- Empty Deleted Items
- Open the Deleted Items folder.
- At the top of the message list, select Empty folder.
- If there are many emails, leave the browser window open until the process finishes.
- If deletion fails, try deleting in smaller batches.
- Permanently erase Recoverable items
Even after emptying Deleted Items, Outlook.com keeps a hidden Recoverable items store that can bring messages back. To purge it:- Under Folders, select Deleted Items.
- At the top of the message list, select Recover items deleted from this folder.
- Select Empty folder to permanently erase them.
- Items removed here are permanently deleted and cannot be restored.
- Free up mailbox storage if it is full
If the mailbox is near its storage limit, cleanup can behave inconsistently. Use the Storage page to clear space:- Go to Settings > Storage.
- Review which folders use the most space.
- Use the options there to permanently delete items (or items older than 3, 6, or 12 months).
- Remember: items still in Deleted Items continue to count toward the quota until that folder is emptied.
- Enable automatic emptying of Deleted Items on sign-out (optional)
To reduce the chance of old items reappearing:- Go to Settings > Mail > Message handling.
- Under Message options, select Empty my deleted items folder.
- Select Save.
If messages still reappear after all three levels of deletion (folder → Deleted Items → Recoverable items) and storage is not full, wait some time and repeat the delete in smaller batches, as large operations can be delayed.
