MacOS – Microsoft Lync Mac crashes on 10.9 Mavericks

macosms office

I have a similar problem like another user had and followed all possible steps including reinstalling and cleaning up Keychain etc before.

The first time I start Lync after a reinstall, I can even see a Menu bar for some seconds. But before any window gets rendered, the Crash Reporter opens.

This is what the error said:

Microsoft Error Reporting log version: 2.0

Error Signature: Exception: EXC_BAD_ACCESS Date/Time: 2013-10-30

Any Ideas how to solve this?

Best Answer

Delete

~/Library/Preferences/ByHost/MicrosoftLyncRegistrationDB.xxxx.plist
~/library/preferences/com.microsoft.lync.plist

and check in

~/Library/Preferences/ByHost/

for additional files with lync or Lync in the name (delete them as well). Then restart Lync.
