Hi, I did a migration for an Exchange server by exporting the accounts to PST files on the old server (Echange 2000) and importing them back in the new server (Exchange 2003). The two servers are not in the same AD or forest, i.e. completely independent of one another (unavoidable). Now it seems that calenadrs are broken, such as free/busy is not being displayed correctly (hash marks), and people are unable to edit recurring appointments (that existed prior to the migration), and get an error message such as: "You do not have the permission to send the emssage on behalf of the specified user". Any ideas as to what is missing from the migration? I am guessing that what has happened is that the ownership perms no longer apparently match, because the old server and new server are completely distinct, not in the same AD or forest and no trust relationship (owned by two completely different companies). If I need to re-set permissions on the server, is there something on the server I can do to "re-sync" these calendar and other object permissions for all users? best regards Mike
