Troubleshooting Address Book Service issues

The culprit.

 Generally speaking the ABS can be problematic from a client or server perspective. I usually start with the client, working my way up from there.

Ask yourself, self…
Is the Cannot Syncronize the Address Book error experienced by all or just onefew individualy?

If its just a few it may be a local issue

Simply to delete the local GalContacts.db and GalContacts.db.idx files. You could then wait and after a raondom time from 1 – 30 minutes (default 30 minutes) you should get a new GAL.
If not check to see if the client can navigate to the ABS URL’s (Seen from configuration information)- often been the problem

What if its Server Related?
The client side GAL files are downloded from the Lync FE IIS. The URL is visible from the Communicator Configuration information (SHIFT + Rightclick icon).

There will be an internal and external URL depending on where the client is connecting from. The URLS look similar to this:-

URL Internal From Server https://FE.lynclab.local:443/abs/handler
URL External From Server

Firstly you can test to see if you can reach these. URL needs to be valid and reachable (proxy issues?etc)
Both sites should present you with an authentication Required box asking for username and password, if you see this the URL is working.

The data located in the backend of the url is situated on the Lync Share that was created during the install process. Ensure that the share is still valid by navigating to it from one of the clients (clients should have read access).

If for some reason the file share is no longer shared or the rights to the share and even the file structure in the share has changed…
You can remedy this by re-publishing the Topology followed by running the Deployment Wizard.

The Lync share needs to have the following 3 files:-

The time and date stamp on these indicates when they were initially created.
The file structure ia as below.

The second level 00000000-0000-0000-0000-000000000000 folder should be time stamped with the last time the AddressBookService was updated (with approximatly 5 minutes added to it).

You could run a Update-CsAddressbook PS command and after about 5 minutes the folder should be updated.

An error I can across recently, the client reported that the “Corporate Address book file appears to be damaged”

Deleting the second level 00000000-0000-0000-0000-000000000000 folder removes the corrupt file. Simply running another Update-CsAddressbook PS command will recreate the folder and its contents.

If the IIS bits are misbehaving its probably best not to fiddle with tnem as the rights, paermissions and accounts required are configured by the installer. What you could try is uninstall lync web component module (control pannel > uninstall …), delete web component directory (C:Program FilesMicrosoft Lync Server 2010Web Components) then reinstall web component through lync deployment wizard.


About Paul B

My name is Paul Bloem and I am employed at Lexel Systems in New Zealand as a Principal Consultant for Unified Communications. I have been working on enterprise voice solutions for over 20 years. My first 10 years were spent working for a Telco in South Africa (Telcom SA). This is where all the groundwork happened as I was exposed to just about every aspect of telecommunication you could imagine. I develop an interest in PBX technologies and eventually became the go-to guy. Next, I had a 10 year run at Siemens South Africa, most of my time there was as a Technical Trainer. During this time VoIP hit the world stage, I had the privilege of introducing VoIP both as H.323 and later SIP across the Siemens HiPath 4000 solution stack. In 2008 I immigrated to New Zealand with my newly attained MCSE, I was ready to go where no PBX Techie had gone before. I was employed to explore OCS 2007 and that was pretty much the beginning of the end for me. I have been working on OCS and Lync ever since. My current role focuses exclusively on Lync and associated technologies.. That includes pre-sales, consulting, architecture and design, training and support. I even get to play in the development space from time to time - focus on play ;-) I was nominated as a Microsoft VTSP for Lync early in 2013 and also awarded Microsoft's MVP award for Lync in 2014.
