My customer's secretary has the other user's mailboxes visible.
The users are in the UK, and the mailboxes are housed between AMSPRD0611, DBXPRD0610, and AMSPRD0610.
It seems like over the last week or two, other user's mailboxes have become inaccessible to the secretary. Removing them from Outlook and re-adding has brought some of them back to life (not always possible when Outlook 2010 auto-adds mailboxes for which you are an owner).
Upon further inspection, it is apparent that I can open an offending mailbox if I go to File -> Open -> Other User's Mailbox, and click Name, then make sure that I choose the *online* Global Address List, and pick the user. This works.
If I allow outlook to use the Offline Global Address list, then the offending mailbox cannot be opened.
I can see in the connection status, that when it fails, it is trying to find the mailbox on AMSPRD0610, and it never succeeds in making the connection, and an Exchange Unavailable message comes up.
So, two questions
1. is AMSPRD0610 down / gone ?
2. Why is the OAB apparently stale ? I have downloaded the full address book in Outlook and it hasn't helped.
I have Cached Exchange mode enabled, but not for shared mailboxes. Only the main mailbox is cached.
get-mailbox tell's me that the offending mailbox is on amsprd0611mb577. How can I see what server the OAB points to?
This is taking up a lot of my time. Any ideas?
