Email retention policy odd behavior Exchange 2013
Posted on 2016-09-22
I applied a "delete after 1 year" and an "Archive after 2 year" policy, both tagged as default on several mailboxes. I understand this is counter-intuitive but it was a request made by the client.
once applied, the users saw very old mail (3-6 years old) coming in as new/unread and flooding their inbox
What could be causing this? I can provide all retention policies if required. There are other "personal" tagged policies. This is exchange 2013 running on 2012 R2
