In general, Outlook will automatically update the Offline Address Book (OAB) for Exchange accounts once every 24 hours.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?/Microsoft Exchange System objects/OAB version 2″ is invalid and couldn’t be updated.” This warning occurs in my situation way after the migration of exchange 2007 to exchange 2013.So I am unable to use the old GUI of Exchange 2007.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? I might have a problem with my Offline Address Book in Outlook.
