Being an office 365 user, I have Microsoft Lync residing on my desktop.  It’s been there for several months now.  However I have never had an opportunity to use this application.

The other day I found a tool on the internet called “Who can Federate Tool ” which will scan all your Microsoft outlook contacts and identify people that are on the federated list???

Having identified whom of my contacts I should (in theory) be able to contact, I have added one of these persons to my Microsoft Lync contacts list.  Next to their name it says “Presence unknown”.

I have then pressed the call button and I get an error message which says “Operation was unsuccessful.  The calling service did not respond”.

I Googled this error message and found this link which explains that the mediation service on my front-end may be stopped. 

Are there any Office 365 users on Geekzone that are using Lync and if so how?

I’m kind of expecting Lync should work a bit like Skype – have I got this wrong?

Any feedback would be appreciated?
