Sending, receiving, and organizing email in Outlook.com
The messages are most likely being hidden from view or moved, not permanently lost.
Try these checks in Outlook.com, in this order:
- Search the whole mailbox
- Use the search box at the top.
- Search by sender name, subject, or a word from the missing message.
- Make sure the search is not limited to Inbox only.
- Check all likely folders
- Inbox
- Deleted Items
- Junk Email
- Archive
- Any custom folders
- If Focused Inbox is enabled, check both Focused and Other.
- Remove message filters
- In the Inbox, set Filter to All.
- If items are hidden by a view or filter, they can appear to have disappeared.
- Check whether items were filtered from view
- In Outlook, go to View > View Settings > Filter.
- Review filter settings such as:
- Date received
- Keywords
- Read/Unread status
- Sender/Recipient
- Importance
- Size
- Clear any filter that could hide the missing messages.
- Check Deleted Items and recover deleted mail
- Open Deleted Items.
- If the messages are there, restore or move them back to Inbox.
- If they are not there, select Recover items deleted from this folder at the top of Deleted Items and restore them if found.
- Check rules, Sweep, and forwarding
- Go to Settings > Mail > Rules and look for anything that moves or deletes mail.
- Check for any Sweep actions affecting Inbox mail.
- Go to Settings > Mail > Forwarding and confirm mail is not being redirected.
- If this happened more than once without any action taken, secure the account
- Change the Microsoft account password.
- Review recent sign-in activity and security information.
- Recheck rules, forwarding, connected accounts, and automatic replies.
If the messages disappeared while drafting a reply, a mailbox rule, filter, or account issue is the most likely cause based on the available guidance. If the items were only hidden, removing the filter or changing the view should make them visible again.
