How does short-term retention work in Microsoft 365?
Short-term retention in Microsoft 365 means that deleted data is saved for a limited period of time before being permanently deleted. The feature builds on trash cans, recoverable objects and version history in services like Exchange Online, SharePoint and OneDrive. The purpose is to enable quick recovery in case of accidental deletion or minor incidents.
What is short-term retention?
Short-term retention is a temporary storage of deleted items that allows them to be recovered within a set time frame.
Exchange Online
Deleted emails are first moved to the “Deleted” folder and then to “Recoverable Items” before being permanently deleted after a certain period.
SharePoint and OneDrive
Files that are deleted end up in the Recycle Bin and can be recovered within a limited time before being permanently deleted.
Version history
Documents save previous versions so that changes can be restored without having to restore the whole file.
Time limit
The retention period varies depending on the service and configuration, but is generally limited to a shorter period of time.
Automatic cleaning
Once the retention period expires, the data is permanently deleted if no further policies are applied.
Administrative control
Administrators can, in some cases, recover data even after the user himself no longer sees it in the recycle bin.
Key features
- Recycle bin: Temporary storage of deleted items.
- Recoverable items: Extra layers for email recovery.
- Version history: Restore previous document versions.
- Timed deletion: Data is permanently deleted after the retention period.
