I am running Outlook Professional 2010 with an exchange account. I archived old items, thinking it was a local operation, only to find that the emails were removed from the server too! Now I am checking the .pst file from my pc. The email in the inbox seem to be there, but I cannot find the sent items (and I am interested mostly in the attachments).
Have they been deleted? In the cleanup setting I don't see anything about deleting.
