We recently changed from using and Exchange server to a POP3 email system.
While the exchange server was first down we were able to access our contacts
(tells me they were local).

To be safe I archived off the email, then setup the POP3 service and brought
the email back in. Now I cannot find any of my contacts though.

Are they stored in some special file? I had them when the Exchange server
was disconnected so I assume there were local.
