Exchange global address not updating

They do for my colleague sitting next to me, so I don’t think it is a server misconfiguration or something like that.Is there any way I can force a manual update of the Offline Address Book (OAB) in Outlook or reset it completely otherwise?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.I am not even sure where to look to even start reviewing any issues, and I am wondering if anyone has seen this before.It's pulling the GAL down, but only a cached copy from earlier today, it seems.

Quite often all Administrators, even Exchange Administrators simply refer to the users they see in the Address section of Outlook casually as the GAL for ease of reference, but really more often than not, you are looking at the OAB.

However sometimes in large complex organisations we have a situation where a new joiner joins and their colleagues want to email them immediately, but they don’t appear in Outlook for them so they call the Helpdesk “Why isn’t Joe Bloggs in the GAL??

” Well, the truth of the matter is that our new joiner Joe is in fact , an update to the Address Book won’t become available to the user until about 48 hours after the change.

This morning I was asked to update the Global Address List and Offline Address Book in an Exchange environment.

You could wait for Exchange to do it automatically (the default schedule is once a day) but what when you want to force the update to take place right now?
