Force OAB update

Once you are confronted with forcing an OAB update you have to concern several steps:

First step – doing the update

  • get-addresslist | update-addresslist
  • get-globaladdresslist | update-globaladdresslist
  • get-offlineaddressbook | update-offlineaddressbook

Second step – wait a few minutes – push the update through FDS

  • get-clientaccesserver | update-filedistributionservice


Perform a full download of the OAB.



In the past I’ve often seen misconfigured NTFS rights cause OAB download fails in Outlook 2007 and 2010.

In a standard installation of Exchange 2010 the OAB’s physical directory points to:

C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\OAB\GUID-XXXXX-YYYYYY-ZZZZZ

You’ve to controll if the “Authenticated Users” group has permissions to read on your OAB directory (-> right click  GUID-XXXXX-YYYYYY-ZZZZZ -> security) and if this right is inherited.
