Another thing that you can do - and I'd do this FIRST - is:
- SIGN OUT FROM LYNC
- From the login screen- select "DELETE MY SIGNIN INFO"
- Then log back into LYNC
See if that clears up. Maybe something stuck in the profile.
you stated earlier that due to GP (assuming group policy, but you're probably referring to policy in general - Lync policy) that it's reverting back to FULL. The object of the game seems to be to find the policy that is reverting the client
to FULL logging, right?
Does the user have the same policy that the other users have? Perhaps, the global policy? please run "get-csuser -identity domain\samaccountname" and verify what clientpolicy is being served AND that the client is under the expected
policy.
You'll need to have access to the Lync server to look at that. But, not being able to verify the policy puts us at a difficult position.
If the user logs in from another workstation - what is the logging set to? does it go from LIGHT -> FULL?
