Address Book Server in Microsoft Lync:
Handling Lync
Server address book is little different than its previous versions. Address Book’s
generation is almost same as it was in ocs 2007 R1\R2, but the related commands
are different now.
1)
Lync Server User Replicator writes Active Directory changes to the backend SQL Server
database (including rtcab) every 60 seconds. You can customize this value between
1 second to 24 hours.
Run
Get-CsUserReplicatorConfiguration
to get this information.
PS C:\> Get-CsUserReplicatorConfiguration
Identity
: Global
ADDomainNamingContextList : {}
ReplicationCycleInterval : 00:01:00
2)
Lync Server Address Book Server runs synchronization pass every 24 hrs. By default
it is 1:30 am local time. During this process Address Book Server pulls the most
recent update from rtc database and writes those changes in address book files.
Run
Get-CsAddressBookConfiguration
to get following information:
PS C:\> Get-CsAddressBookConfiguration
Identity : Global
RunTimeOfDay
: 1:30 AM
KeepDuration : 30
SynchronizePollingInterval : 00:05:00
MaxDeltaFileSizePercentage : 20
UseNormalizationRules : True
IgnoreGenericRules : False
EnableFileGeneration : True
3)
Update-CsUserDatabase
in Lync Server 2010 does the same thing as abserver.exe
–RegenUR does in OCS 2007 R1\R2.
4)
Update-CsAddressBook
in Lync Server 2010 does the same thing as
abserver.exe
–SyncNow does in OCS
2007 R1\R2.
Troubleshooting:
If Address Book Files folder doesn’t have the right permission configured, you will
get the following error.

Address Book download at clients
Lync also will
not immediately download changes to the Address Book files when first launched,
but instead wait for a random interval of time between 1 and 60 minutes.
Configure
GalDownloadInitialDelay on the lync clinet machine if you don’t want clients to
wait for a random interval.
