Retention policy and hard delete
What Adam is referring to is the "old", Exchange-style retention policies. If you have configured a retention policy via the Security and compliance center, the mailbox and any content subject to the policy will be preserved for the selected duration. In case the entire mailbox object is removed, it will still be preserved as "Inactive" mailbox. Review the documentation for more details: https://support.office.com/en-us/article/overview-of-retention-policies-5e377752-700d-4870-9b6d-12bfc12d2423
- Thanks Vasil, i thought this might be case.
How can i test this? Since our setup is Hybrid i have to delete the AD Object on-premises, wait for AAD to sync and remove the Object from Office 365 which then will soft delete the mailbox. If i then initiate hard-delete how do i recover the mailbox?Hey Karam,
I would do your testing with test data, as to be sure you dont lose anything. Also remember you need to give the retention policy a good 24 hours to be sure its in place.
If this functions like the litigation/legal hold, a deleted mailbox that was being preserved will show up as an inactive mailbox. You just follow the restore process:Hope this helps!

- Thanks Adam.
The article covers inactive mailbox that remains in the Office 365 recycle bin for 30 days (soft-delete), if the retention policy is applied and an admin hard-deletes (permanent) the mailbox how can be recover this?
I also found this when researching it which may be helpful in your case - https://www.codetwo.com/admins-blog/office-365-litigation-hold-vs-retention-policy/
It has a nice comparison table and everything.
Digging in more i only found the generic, when legal matters are going on do litigation hold, for company wide stuff retention policy's.
So i think you should be find doing a retention policy, just note it can take up to 24 hours to be in effect.
Thanks for the call out VasilMichev
