How to recover files in Microsoft 365?
Restoring files in Microsoft 365 can be done through the Recycle Bin in OneDrive and SharePoint or through recoverable items in Exchange Online. Version history and retention policies make it possible to restore previous versions and deleted items. External backup provides additional security and the possibility of recovery even after the standard retention period has ended.
Methods for file recovery
Microsoft 365 offers several built-in methods to recover data in case of accidental deletion or modification.
OneDrive Recycle Bin
Deleted files go to the OneDrive Recycle Bin where the user can recover them within a limited period of time.
SharePoint recycle bin
Deleted documents on SharePoint sites can be recovered from the site recycle bin and the secondary recycle bin if necessary.
Version history
Previous versions of documents can be restored directly, making it possible to revert to an older copy without losing the entire file.
Recoverable objects in Exchange
Emails that are accidentally deleted can be recovered from Exchange Online during the retention period.
Retention policies
Retention policies and Legal Hold ensure that data is not permanently deleted before the specified time, facilitating recovery.
External backup
Backup from a third-party solution enables data recovery even after the end of the default period.
Administrative reset
Administrators can restore files and user data for the entire organization if needed.
Practical steps for recovery
- Check the Recycle Bin: Start with the OneDrive or SharePoint Recycle Bin.
- Restore previous version: Use version history if the file has changed.
- Administrator recovery: If the user cannot recover the file, contact an administrator.
- Exchange Online: Recover deleted emails via recoverable objects.
- Third-party backup: In case of longer-term needs or extensive recovery, external backup is used.
