Lync 2013 Client not updating Out of Office Flag

Reolution:

 

This was a known issue and it should be solved after the following Lync client update 15.0.4551.1005 http://support.microsoft.com/kb/2825630/en-us,

Make sure that you have installed latest Lync client updates and check if the issue still exist.

Also you can solve the problem by the following:

Ø  Rename the Cache in C:\Users\<Name>\AppData\Local\Microsoft\Communicator. Then log in to the Lync Client, add a custom “What Happening” message and then delete it. It will be reset the field back the original “Whats happening today” message

Ø I you are uding Lync wendows app store macksure you installed the latest updated Lync client from windows app store
