Microsoft Office Communicator Mobile is a Unified Communications client for Microsoft Office Communications Server 2007. Communicator Mobile runs on Microsoft Windows Mobile 5.0 or 6.0 software for Pocket PC and smartphone devices.

Here are some screenshots from my phone.

A presence indicator is installed on your Today screen.  (yes I know that’s a lot of unread email – that’s what I’m going to do next.  I swear!)

My personal contact groups.

 

Expanding my Nortel contact list.  Yes, Nortel.  That is federation in action, so this is not limited to contacts inside your corporate network!

 

More detail on Kirsten Gilbertson from Nortel (her contact details deliberately removed for privacy reasons).  I can she’ll be free at 6:30pm (that automatically comes direct from her Outlook calendar) – and I can call any of her phones, email her, or send a txt message straight from Communicator.

How cool is that!!??
