Can't sign in with MS Lync Since I updated OS X to 10.8.5 a week ago, I have issues signing in with Microsoft Lync: the program crashes every time. I never had issues before so I thought the latest OS update caused the issue, however all my colleagues can use Lync as before.

I installed all Microsoft updates as well ...

Lync returns the following error details

Microsoft Error Reporting log version: 2.0

Any ideas? thx!
Solved this today. I'm not sure what finally solved it but this is what I did ...


Install the latest Mountain Lion Update which was published today
Completely uninstall Lync as described here http://support.microsoft.com/kb/2691870 
Reinstall Lync + do the Lync update to v14.0.6
Change my password - as my old one contained a German special character.
