Work´s fine for me. Just do not upgrade to the new version 13.1 stay on 13.0.0
The only thin Your missing is «desktop sharing»

Latest version has crash issues. I think it was 13.1.1.

App crashes when you receive a message.

Are you blind? Your question has already been answered 3 times.

I think YOU are the blind one. Not ONCE was GM specified to be the version of Lion referenced above.


In GM version of Lion, 13.1 and 13.1.1 both crash the same. 13.0 works.

GDO, thank you. I need desktop sharing and our servers don allow 13.0.0 so i need to wait for MS :(

by the way communicator 13.1.1 crashes on snow leopard too, might just be a regular MS "by design feature"

dani, i noticed that as well. But in SL it crashes "once in a while", last time i tried on Lion, it crashed every single time you received an IM.

Lets hope MS can remove this "feature" soon as its blocking me from using Lion.

yes in SL it was very occasional, but in Lion every time a new conversation, call or IM starts it crashes.

FYI: If you have been using TimeMachine since Nov 2010 you can restore Communicator from then and you would be fine. Worked for me.

Where are all the old comments? Does it really work? Last time i tried it kept crashing whenever i received an IM. I don't remember the version but 13.0.0 is stable, however it doesn't have desktop sharing.
