Upgraded from PB2 to PB3. I did the language change in PB2 - so lync was working then. In PB3 - Lync still works and accessing the Lync preference's doesn't crash the app. Overall happy :)
 
Also can confirm that changing the language (by reordering the languages in the Preferred Languages section of "Language and Region") to French and then back to English worked perfectly--didn't even reboot.
 
DP7 seems to have fixed Lync

Hi all, It looks like DP7 seems to have fixed Lync - I can now access preferences with no problems :)
 
i've just registered myself here to post a possible fix. i've been following this thread for a while since i installed OSX 10.10 DP2 and none of the solutions listed here worked for me. but after reading the last posts i tried this: change the system language back to english (my native language is Portuguese), installed DP8 (Public Beta 3), installed latest lync 2011 and voilá! everything is working again with no constant disconnects. hope it helps! (sorry for my english)
 
Lync working for me

I have been trying to get lync to work on Yosemite since first beta release. I finally have it working thanks to the comments from posters in this forum. I tried the change of language on DP7 and lync immediately started working.
1 go to setting "regional language prefs"
2. Move second place language in the list to the top (by dragging it up list)
3. Restart
4. Return original language to top of list
5. Restart
6. lync now working

I have since upgraded this morning to DP8 and everything still working.

I am connecting to a company lync 2010 server, using OS X client 14.0.9

I had Lync working in most of the DP versions, but the application would not quit, forcing me to do a force quit. Also like others, the preferences would crash the app. DP8 seems to have fixed both of these issues.
 
installed PB3 on a MBP after testing on an iMac but forgot about Lync :confused:

Anyway this thread helped a lot, added a new language in prefs as default and changed it back straight away without any restarts and it's now working for me incl Lync preferences.
 
although lync now opens and I can send messages, I can't receive them.
anyone else seeing that?

it's an office365 sub.
 
check library name

try with (one line):
sudo ln -s "/Applications/Microsoft Lync.app/Contents/Frameworks/USBHIDWrapper.framework" "/Applications/Microsoft Lync.app/Contents/Frameworks/USBHidWrapper.framework"
 
It does indeed work when you switch between English and English UK however does not work between English vs other (e.g. Polish)

Switching to English, reboot - works like a charm
Switching back to Polish - same old MS crap :(
 
try with (one line):
sudo ln -s "/Applications/Microsoft Lync.app/Contents/Frameworks/USBHIDWrapper.framework" "/Applications/Microsoft Lync.app/Contents/Frameworks/USBHidWrapper.framework"

Awesome, thanks - that worked :)

Language trick does the trick however after certain time Lync acts as connected yet people stop seeing me online - after reboot it goes back online for some time, then stops again...
 
I too have tried everything suggested so far and am having no luck. I've also upgraded to the 10.10 GM.
