I am not able to login to Lync 2013 client after the fresh
installation of Lync Server 2013 with CU2. I am getting the error
standard error message “The user name, password, or domain appears to be
Tried with different accounts as well, but still getting the same error message. I found an update for Lync 2013 client and installed it.
After the update, tried Login, still the same error message. Now I enable the logging on the client so that it will generate the event in case of failure. I found the Event ID 3, 1 and 12.
Now as per the event, there’s something wrong with the installation or the files of Lync Client 2013 which got installed. I installed the full version of Office 2013 Lync Client, now I tried with Lync Basic client and it failed with the same error message.
I decided to check the issue with Lync 2010 Client and installed the client after uninstalling the Lync 2013 client from the workstation.
Now I tried to login to the Test account and it worked, no more error with Lync 2010 client.
Resolution/Workaround: Install Lync 2010 client.
I am not sure, why is it failing to login with Lync 2013 client, I am still looking into the issue and will update the post once I find the solution.
