If this is not the case or for some reason normal replication is failing then a manual process can be used to toss out the entire copy of AD information in the SQL database’s address book store and regenerate a completely new copy.

To rebuild Lync’s copy of the AD data simply use the cmdlet.

In that case the whole OAB is being downloaded again.

In a later section, it is explained how to modify this.

This is called the Offline Address Book and is being generated on the Exchange server.

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.

For standard 32-bit operating systems the registry path below is the same regardless of the client versions (OC 2007 R2 with July 2009 update or Lync 2010 RC) but previously 64-bit operating systems running the 32-bit only OC 2007 R2 client had to have the setting created under the Wow6432Node policies key.

When you have Cached Exchange Mode enabled, Outlook by will by default cache the main Global Address List as well.

To trigger an immediate download two steps must be taken on the client workstation.

If the key name doesn’t exist, Outlook uses a value of 8.

Prompt before for full download As the OAB can be quite large in some environments, it could be wise to be prompted when Outlook wants to download the full OAB.

Be aware that is stuff is more process intensive than the automatic delta synchronization.

This step should not be necessary under normal circumstances.
