We had a directive to remove the Retention Policies for our mailboxes. We had a policy applied to Inbox and Deleted Items. We ran a script to change them all to $null.
Get-Mailbox -ResultSize unlimited | Set-Mailbox -RetentionPolicy $null
In the ECP all the mailboxes don't have a retention policy now.
In my Outlook, I've noticed that my Inbox and Deleted Items still show the policy but new email isn't stamped with the expiration anymore. Will all existing email remain tattooed with the old policy or will they all get reassigned in time?
