A user was provided a .pst export of a former employee for review. Instead of opening the .pst (9GB) she imported it into her own mailbox. I now need to remove all of those items from the mailbox.
I was thinking of deleting everything which was added from Outlook from the moment she performed the import (not sure if this is possible).
I am looking for the correct powershell command, possibly a new-mailboxexportrequest with -deletecontent. I would need help with the where clause to select just the emails imported from that other mailbox. Open to other ideas.
Every folder was imported, drafts, deleted items, etc. etc.
