I was wondering if it was possible to start a new Office Communicator conversation from a link in the same way that you can start start a new email with the "MAILTO:" link. I am mostly looking to do this from within Outlook 2010.

Actually, not serves the need. i have created a hyperlinlik like this <A href=""> Ping Me </A>" the problem is, instaead of opening a window with my name and the initiators name for chat, it says like "Microsoft Office Communicator is Already Running" Is thr any reason behind this? – user197826 Feb 13 '13 at 5:05

in addition to the SIP: uri mentioned from bquaresma, if you have telephone integration, you can also use the tel: uri to make a phone call. In my outlook signature, I have my phone number as tel:+15551234567 Outlook just shows it as 55501234567. When people click on it, it initiates a phone call to me.

Thank you Brian, I'll be sure to keep this in mind when our phone integration starts up next year. – Rustafur Nov 3 '10 at 18:55
