Author by Matt Sims

In certain circumstances it's very useful to delete current Lync Server 2010 address book files and generate a fresh copy.  Below are instructions on how to do so:
  1. Navigate to the following location within the Lync Server 2010 file share: serverLyncShare1-WebServices-1ABFiles0000000-0000-0000-0000-0000000000000000000-0000-0000-0000-000000000000  [NOTE: The numerical directory names beneath the 'ABFiles' directory may be different]
  2. Remove all the files in the directories beneath the 'ABFiles' directory from their current location to a backup / temporary location
  3.  Execute 'Update-CSUserDatabase' from the Lync Server Management Shell to  initiate the user replicator process
  4. Wait five minutes, and then execute 'Update-CSAddressBook' from the Lync Server Management Shell to generate a new set of address book files
