Recently upgraded to Exchange 2007 and implemented OWA which works out great but one minor annoyance... the Documents button does not show up for any of the mailboxes that happen to be placed on a BE 2007 server that is not in the same AD Site as the FE server. If I move the move mailbox to a BE server located in the same AD site, it shows up but disappears again as soon as the mailbox is moved again.
There are no error messages. All servers OS Server 2003 sp2, w Exchange 2007 sp1 w the Rollup 7 installed.
any ideas are appreciated.
