To accelerate testing of your ABS Normalization rules it is sometimes beneficial to delete the 'galcontacts.db' file, update the address book and log back in again. To accelerate this process so the 'galcontacts.db' file is downloaded immediately upon logon the following registry entry can be added to the client workstation running Lync 2013.
reg add HKLM\Software\Policies\Microsoft\Office\15.0\Lync /v GalDownloadInitialDelay /t REG_DWORD /d 0 /f >null
Location to galcontacts.db is: %userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\email@example.com
The location is different than it was with Lync 2010. To enable Lync download immediately for the Lync 2010 Client:
reg add HKLM\Software\Policies\Microsoft\Communicator /v GalDownloadInitialDelay /t REG_DWORD /d 0 /f >null
Location to galcontacts.db is: %userprofile%\AppData\Local\Microsoft\Communicator\firstname.lastname@example.org
