Hello to all, I am in the process of migrating users from an Exchange 5.5 server to exchange 2003. After moving the first group we notices that userA was not able to view userB's calendar. One useC was a delegate for userD and couldn't see his calendar either. After userD open his calendar and, without changing anything, but just clicking ok. A few minutes later it started working. Is it possible that after moving the mailboxes these permissions are been reset? Any way to avoid this for the rest of the users to be move? Best regards, Juan
