Global address list cached mode not updating

When I look up the conference room in the Global Address List, it doesn't show up. So as I understood from our Sys Admin, the oab files are generated on one server, and rely on the file replication service on the global catalog servers (we have 2 of them) to copy the oab files to each of the servers.However, if I delete my files (Offline Address Book) then I can see the new conference room in the Global Address List. The service was not started on one of the servers and therefore some users were getting old oab's while other users were getting fresh copies. if you're having this issue, make sure the file replication service is started. Chances are good that OAB generation is failing for some reason.This situation however is extremely rare since the default maintenance time on Exchange is at AM and updates and downloads are usually performed during working hours.*** NOTE: The GAL is essentially a real-time / online representation of AD Objects that are Mail Enabled for Microsoft Exchange *** The GAL contains information for all email enabled users, Distribution Groups, and Shared Mailboxes and Exchange Resource Mailboxes.GAL Objects are directly viewable in the Exchange Management Console/Shell and OWA and Microsoft Outlook BUT ONLY IN ONLINE MODE – The GAL will only present objects that have AD Attributes beginning with ms EXCH* (and some others) populated that it uses to filter on.

This does show up in the event-logs of the Mailbox server that does OAB generation, but the logging generally isn't turned on high enough to tell you I've had this problem before - not for Exchange 2010 I will admit (it was Exchange 2003) but the symptoms were exactly the same, so with a bit of luck so is the solution.

To make this more confusing, some users are able to see the conference room in the Global Address List without removing their offline address book. Unfortunately I never got to the bottom of it wasn't working, but I rebooted all of my Global Catalog servers and it magically started working again.You can see the list of attributes that will be put into the GAL using When Outlook users are running in cached mode, they rely on the Offline Address Book (OAB) to provide them with access to one or more addresses (that are always available when they are connected directly to Exchange) The OAB is rebuilt and downloaded on a default schedule as shown below.
