Unable to see all mailboxes on Exchange 2007 server
Currently running EV 10.0.1 installation against Exchange 2007 servers. Have imported/migrated users from an SBS Exchange server into full Exchange 2007 server. Several previous SBS users have shown up in the archive after a synch run , several have not.
AD wise, there is no difference between the two groups of users. They all came from the same location, are all in the same AD domain. We are seeing only half the users.
Event logs do not show errors or warnings with respect to this issue.
Where should I start troubleshooting?
