I am receiving the following error when attempting to launch Lync on my Mac

Stats:

OS X 10.9.1

I have tried EVERY idea/suggestion/reply I've been able to track down - without success.

Removed the 'unknown' entry in KeyChain (there was not one, but I checked)

Removed the OC_..... KeyChain entry

Removed the Application entirely (including Log, ByHost, Preferences, etc)

Reinstalled the Application and updates.

Have performed both 'Verify Disk', 'Verify Disk Permissions' and 'Repair Disk Permissions', 

All variety of fixes/combinations still result in immediate crash.  The Application does not even show up - just straight crashes.

I have Office for Mac installed as well (running fine).

Any help/suggestions are greatly appreciated.

I am facing same issue as well. I have slightly different signature though:

Hi,

It seems to be a known issue about Lync 14.0.7 version. You can try to uninstall Lync client with the help of the link below and then install Lync 14.0.6 manually on Mac to have a test:
