The lack of video conferencing sales mobile Lync short. It almost makes upgrading to 4G a mistake.

Awesome stuff

Use it constantly, but would love to see video integration.

Please upgrade to Lync 2013, and support for voice & video chat.

Lost all my contacts. IM doesn't work saying please retry sending message.

Great when it works. I work in IT, I like this app since it allows me to move from office answering people and communicating with other people in IT office. Only.problem is messages don't always come true and has a lot of connectivity issues. I'm almost always on WiFi so I can't really blame it completely on the carrier but I could be wrong.

Essencial

Awesome!

Works great!

One would think since its from Microsoft it would be nicely integrated. I don't get notifications. It isn't listed in me and then there's the vibrate everytime u get an IM. Can't turn it off!!!
