First, using Set-Mailbox I need to change the Name, Alias, Display Name, Sam Account Name, and User Principal Name.The change should be visible almost immediately if you're viewing the global address list in OWA, or viewing the “All Rooms” address list in Outlook.In general, Outlook will automatically update the Offline Address Book (OAB) for Exchange accounts once every 24 hours.When it didn’t or when you want to make sure you do have the latest OAB available, you could manually trigger an update from within Outlook as well.I might have a problem with my Offline Address Book in Outlook.For me, new colleagues are not showing up and the contact pictures aren’t displaying either.
In that case, you can completely reset it by deleting the files making up the OAB or by recreating your mail profile.
Please note that I’m using Exchange 2007 with a separate CAS, HT, and Mailbox Server.
First, let’s go over what is happening and why it is and then we’ll go over how we can force the OAB (Offline Address Book) or GAL to update with these users.
But what if, like me, you need to have it update right away due to something like a Black Berry server?
Through trial and error, I’ve found out WHY the user is not put into the Global Address List right away and how you can force it there.Before cloning the accounts he had removed the mailbox from the template account however it had left the Exchange attribute “Show In Address Book” populated. When in Adsiedit open up the Default Naming Context then open up your domain name and browse to the OU that the user is in that you need to modify. Right click the user account and select properties.
