Oui, j'ai besoin d'une solution
I made a bit of an oops during my test phase of rolling out EV and did not pay attention/comprehend the significance of Retention Category when I created a new provisioning group and then assigned a couple of mailboxes to it. The category was one of the built in Exchange policies (clean up draft after 30 days) which now has applied to the archives. To fix the issue I think I will need to:
1. Export the archives to PST (does this empty the archive of all files?)
2. Move the mailbox to a new provisioning group
3. elete all of the shortcuts out of the mailboxes
4. Re-import.
Does this sound correct? Or so I need to export it, then delete the archive and recreate?
