Microsoft - Enable Auto-Expanding Archiving
Note:
Understand the following restrictions:
- After you turn on auto-expanding archiving for your organization or for a specific user, it can't be turned off.
- Administrators can't adjust the storage quota for auto-expanding archiving.
- Auto-expanding archiving prevents you from recovering or restoring an inactive mailbox. This means if you enable auto-expanding archiving for a mailbox, and the mailbox becomes inactive in the future, you won't be able to recover the inactive mailbox or restore it.
After you enable auto-expanding archiving for an inactive mailbox, the only way to recover data is by using the content search tool in the Microsoft Purview portal to export the data from the mailbox and import to another mailbox. For more information, see the Inactive mailboxes and auto-expanding archives.
