How to recover emails in Microsoft 365?
Email in Microsoft 365 can be recovered through the Outlook client or Exchange Online through trash, recoverable items, and retention policies. Administrators can also recover email that the user no longer sees. External backup solutions provide additional security and recovery of older or extensive email data.
Methods for email recovery
Microsoft 365 offers several ways to recover emails that have been deleted or lost.
Trash in Outlook/Exchange
Deleted emails are first placed in the trash where the user can recover them within the retention period.
Recoverable objects
If the message has been deleted from the Recycle Bin, it can often be recovered via Exchange Online’s recoverable items.
Retention policies
Retention policies and eDiscovery ensure that emails are not permanently lost before a specified period of time has passed.
Administrative reset
Administrators can restore emails for individual users or entire mailboxes if needed.
Third-party backup
External backup enables recovery even after the standard retention period and in case of extensive data loss.
Version history of attachments
Attachments can sometimes be restored to previous versions via SharePoint or OneDrive if they have been saved there.
Check filters and views
Sometimes emails can “disappear” due to filters or sorting settings. Always check this before restoring.
Steps to recover emails
- Check the Recycle Bin: Look for deleted messages in Outlook or the web.
- Use recoverable items: For messages that are no longer in the trash.
- Administrator reset: If the user cannot reset himself.
- External backup: In case of legacy or extensive recovery needs.
- Verify recovery: Check that emails and attachments are correctly recovered.
