Apply Retention Policy to Default (Sent and Deleted) Folders
In Exchange Online we have a shared mailbox where I want to have a policy to delete everything more than a year old from the Sent Items and Deleted Items folders.
I created a Retention Label (Delete Content after One Year) and Published it to all Exchange mailboxes. In any mailbox I can select a folder and apply the policy to any folder except the default ones.
If I select Sent Items or Deleted items my only choice is still "Use parent folder policy". If I manually select an item in those folders I can choose the new "Delete Content after One Year" policy.
How do I apply the policy to the default folders? Or is there another way to automatically delete everything over a year old.
- You cannot assign such tags manually, you configure them in a policy and they apply to the corresponding folders. If you want to assign it via Outlook/OWA, you need to create a "Personal" tag.
Moreover, the default "Deleted items" tag will be ignored if used in the default MRM policy, this is a change Microsoft made few years back, as apparently too many users were complaining about items in the Deleted items folder being deleted. Go figure. Anyway, the change sticks, and nowadays it's best to create a different policy, assign a Delete Items tag to it, then assign it to the user(s) in question.
- As you want to target specific folders only, you need to use old-style Exchange retention tags/policies. Not the ones in the compliance center.
- I have some of both. I can apply either kind to most folders but neither is available to apply to Sent or Deleted items folders.
- Those are Default folder, so you'll need a tag of the corresponding "kind". Or a Personal tag.
