Exchange global address book not updating

Another way to make sure that you get a fresh copy of the OAB is by renaming the oab-files to when Outlook is closed.

The only thing that work was to delete OAB file C:\Users\%username%\App Data\Local\Microsoft\Outlook\ BUT I have to do that every time when I create a new user or the user profile like phone numbers.

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

Rather than waiting 24 hours for Outlook to update the Offline Address Book on its own, you can force an update via the Send/Receive menu button.

You can disable the option “Download changes since last Send/Receive” to make sure you get a complete fresh copy of the OAB but this could take longer to download.

The Global Address List is a directory of contact information that is stored in a central place called the Exchange Server.

As a faculty/staff member, your Outlook program automatically syncs with the Exchange server on a regular basis. For example, say a new person joins your workgroup.

I'm having an issue with Exchange 2010 and Outlook 2010. This problem started after we flattened our domain. We migrated all the users from the the sub to the top using the ADMT and then we took down sub. To be sure, does OWA (which uses live information) reflect the GAL correctly? The first thing you should do is on a test workstation, is delete the *files.

Essentially, the issue is the GAL is not updating in Outlook. I looked at the recipient filter of the GAL, it's below for reference: (Alias -ne $null -and (Object Class -eq 'user' -or Object Class -eq 'contact' –or Object Class -eq 'ms Exch System Mailbox' -or Object Class –eq 'ms Exch Dynamic Distribution List' -or Object Class -eq 'group' -or Object Class –eq 'public Folder')) The next thing I'm going to try is creating a new GAL and making it the default, if necessary. That will force Outlook to download a complete GAL. If so, it is probably that the incremental update files haven't updated correctly.

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?

To get the OAM to immediately generate run the following command: Update-Offline Addressbook “name of offline address book”.

We have another server in the wings waiting to be deployed, but we need to address the problem in the meantime. If it does not, then it is the generation or distribution process that is failing.
