If you are not seeing correct contact information in the GAL for someone that has a valid email address (i.e.
someone who just received a CUMC email account, a new student, someone who recently changed their directory information) please use the steps below to synchronize your computer's locally cached version of the GAL.
If the update mechanism appears to be broken for you, it could be because of a corruption in your OAB or in your mail profile.
In that case, you can completely reset it by deleting the files making up the OAB or by recreating your mail profile.
My computer slows down when Outlook shows the "Updating Address Book" status. In computers with slow hard disk drives, such as portable computers, or running Outlook in a Virtual machine, the process of updating the address book can slow down the computer if the hard disk is fragmented.
To improve offline address book download performance, try defragmenting your hard disk.
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?
It can be accessed when using a CUMC email account with Outlook and Web Outlook.In Cached Exchange Mode, Outlook 2007 & 2010 downloads a local copy of the Global Address List (GAL), but only updates it every 24 hours.In order to reflect any changes or updates made to the Global Address List, you can force Outlook to download a new copy of the GAL.The default configuration for Exchange 2010 has the Address Book will update every 24 hours at 5am.During this process all new email addresses are added to the Global Address List ready for when the clients next connect and refresh their copy of the address book.
