I have a mailbox export request that I need to complete to export all mail matching a specific criteria. Easy enough request sort. I know the new-mailboxexportrequest using content filters can accomplish what I'm looking for with one problem. The particular mailbox switched email addresses at some point in the past. I need to export all mail sent to or was sent from using the new email address only. Lets say the new smtp address is firstname.lastname@example.org for example. How can I accomplish this request?
What I thought of doing is determine when we thought the change happened and use sent and received content filter dates to accomplish this. This would be less than ideal.
