Hi We have a large Exchange Environment consisting of 10 Exchange 2003 Servers (SP2) (40'000 users). We are currently restructuring mailbox locations and performing bulk mailbox moves. Whenever we move a large number of mailboxes we have Issues whereby people can no longer access the Calendar of a users mailbox that has been moved, For example if User B and C have access to User A's Calendar and User A has her mailbox moved then user B and C can no longer aceess User A's Calendar, We have had about 150 cases so far, all we can do is wait about 5-7 days and the issue resolves itself. We have tried recreating the users profile, Ensuring Cached mode is off, uninstalling and resinstalling office, stopping and restarting the information store, we even tried restarting the Exchange server the users mailbox was now on however this does not resolve Looking at the web i can see people have had this issue before but cant see any resolution Anyone on here have any ideas? Thanks Nick

Losing access to additional mailboxes isn't uncommon, because Outlook only redirects the primary mailbox. It doesn't know that the additional mailbox/folder has been moved and cannot redirect. Usually you simply remove the additional mailbox and then reattach it and it works fine. If both the primary and the additional mailbox have been moved to the same location, then you will often not have to do that. The delay that you experiencing would tend to point to an issue outside of Exchange. Poor replication, something like that. There is nothing in Exchange that I can think of that would cause that delay, with the exception of the permissions cache, but that is two hours and I don't you can go as high as 4 days with the cache. Doing anything with Office installed on the workstation is a waste of time. Restarting the services would flush the cache, so that rule that out. Removing the permission, waiting two hours and then putting it back in might kick things along a bit. However given the size of the environment, replication is where I would be looking.

That's been my experience, too. Although recreating the profile should have caused them to add the mailbox (or folder) to the new profile. I wonder if that 5-7 day gap is when the other mailbox gets moved! The only other thing I can think of is that the legacyExchangeDN might be getting changed when the mailbox is moved. That wouldn't be something a simple mailbox move would do, though. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
