Since I’ve got Microsoft Office 2004 installed (see this post), I can use the Microsoft Messenger that comes with it to connect to the Office Communicator service that Fontys has setup for all its employees.
What I didn’t know was that there is also a browser based version (in our case located at http://im.fontys.nl/). It has limited functionality in that it only handles chat, no video, no audio. But it works on a Mac in Firefox without a problem.
I know, it is of limited use if you don’t work for Fontys or if your company doens’t Office Communicator. But otherwise it is something to remember not just when using a Macbook without Office 2004, but also if you’re not at your own PC and want to see if your colleague is available to answer a question.
