Use Outlook.com’s Recover items deleted from this folder option on a computer, because messages absent from Deleted Items may remain recoverable there for up to 30 days.^1^
Recover the messages
- On a PC or Mac, sign in to Outlook.com with the affected Hotmail account.
- In the left folder list, select Deleted Items.
- Above the message list, select Recover items deleted from this folder.
- Select the missing messages—or select all available messages—and choose Restore.
- Check the original folders and Inbox for the restored messages.
This recovery area cannot be accessed from the Outlook mobile apps or a mobile browser. Messages removed from Deleted Items remain recoverable for 30 days; after that period, recovery may no longer be possible.^1^
If nothing appears in the recovery list
Check whether the messages were moved or hidden rather than deleted:
- Search using a known sender, subject, or phrase.
- Set Filter → All in the Inbox.
- Check Archive, Junk Email, custom folders, and both Focused and Other tabs.
- On a computer, open Settings → Mail → Rules and remove or disable any rule that moves or deletes messages.
- Open Settings → Mail → Forwarding and check for forwarding that you did not configure.
Microsoft notes that Junk Email is automatically removed after 30 days and is then unrecoverable.^1^
Secure the account if the disappearance was unexpected
If you do not recognize a rule, forwarding address, or other mailbox change:
- Review the Microsoft account Recent activity page for unfamiliar access.
- Change the account password.
- Remove unknown rules or forwarding settings.
- Sign out other sessions and enable two-step verification.
The Recent activity page displays account sign-ins from the previous 30 days, including available device or application details.^1^
If the messages are absent from every folder and from Recover items deleted from this folder, contact Outlook.com Support:
- In Outlook.com, select Help on the menu bar.
- Enter a description such as “All Hotmail messages disappeared and are not in Recoverable Items.”
- Complete the suggested self-help.
- Scroll to Still need help? and select Yes.
Support can review the mailbox state, but if the messages are outside the available retention period and no longer exist in the recovery area, they may be permanently unrecoverable.^2^
