Managing personal Outlook.com account settings, security, and privacy
A mailbox rollback is not described as an available self-service recovery option in the provided guidance. The supported recovery path is to check the folders and recovery options that can still contain deleted mail.
Since rules were already removed, use this order:
- Check Deleted Items
- In Outlook.com, open Deleted Items.
- If the missing messages are there, select them and choose Restore.
- Check Recover items deleted from this folder
- In Deleted Items, select Recover items deleted from this folder above the message list.
- If the missing messages appear, select them and choose Restore.
- For Outlook.com, messages removed from Deleted Items are recoverable for 30 days.
- Messages deleted from a child account can’t be recovered.
- Check Archive
- If the attacker archived messages instead of deleting them, open Archive.
- Select the message and choose Move to > Inbox.
- Check filtering
- Above the message list, select Filter and set it to All so messages are not hidden by a filter.
- Check account activity
- Review the Recent activity page for sign-ins from the last 30 days to confirm whether the account was accessed unexpectedly.
Important limits:
- Recovery of messages removed from Deleted Items is not available in Outlook for iOS, Outlook for Android, or a mobile browser. Use a computer.
- If the messages do not appear in Deleted Items, Recover items deleted from this folder, Archive, or after clearing filters, the provided guidance indicates they were likely permanently deleted and may not be recoverable.
If self-help does not restore the messages, use Outlook.com support from Help in the menu bar, enter the issue, then scroll to Still need help? and select Yes.
