Updating global address list

/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.Due to various synching schedules, it can take up to 48 hours before you could actually see a change in Outlook after a modification has been made on the Exchange server or in Active Directory.

And since this website’s main focus is on Outlook, it makes sense to start with Outlook as well ;-).In Outlook 2010 there was an easy to access function to update a contact in my contact list from my corporate Global Address List.This was very helpful when someone transferred from one organization or site to another, for example. To solve this issue, you need to do the following steps.Start Adsi Edt (be careful with this change) Go to default Naming Context Microsoft Exchange System objects Open the properties of the objects which gave the warning in the Power Shell message.Key: Note: As Outlook 2010 an Outlook 2013 can connect to multiple Exchange servers in a single mail profile, there is an additional “Offline Address Books” subdirectory which contains folders with GUID references which contain the actual oab-files.Finding out which GUID represents which mail account isn’t very straightforward but looking at the “Date modified” value of the folder should give you a good indication if you don’t want to simply delete all folders or rename them to In a later section, it is explained how to modify this.There are various Registry settings available to control or modify the update and download behavior of the Offline Address Book in Outlook.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.
