I have one issue and hoping you can help me out.
Currently Exchange 2007 SP1 is in domain A
Users are in Domain B. Domain A and B have trust relationship.
User 1 needs to have permission to user 2's calendar.
User 2 grants permission to user 1 in domain A\useraccount format.
The problem is all users (including user 1) log on to Domain B not A. Therefore user 1 can't get into user 2's calendar. I can only grant permission in Domain B\useraccount format via EMS in Exchange 2007 with fullaccess. However, user 1 only allowed to have access to calendar. I can't find any EMS command specific for calendar. Because using EMS, I can specify domain name. I have used PFDAVAdmin, but there is no way that I can specify domain B. Does anybody know the EMS command?
