eWeek has posted on article on the mandatory upgrade.  You can read it here.  Another aricle on the subject here.

The MSN Messenger team has started enforcing that 6.2.0205 is the minimum build of 6.1/6.2 allowed to connect to the MSN Messenger service.  To enforce the new minimum version we have started a mandatory upgrade.

If you are running 6.1 or 6.2 and haven’t upgraded to 6.2.0205 when you Sign In to MSN Messenger you receive a notice that says:

A newer version is available.  You must install the newer version in order to continue.  Would you like to do this now?

If you choose “Yes”, that will start the MSN Messenger setup process.  If you choose “No”, you will be returned to the Sign In window.

If you have Messenger configured to start when Windows starts, you’ll get this prompt when you first login to your desktop.

There’s a link from the dialog box to the MSN Messenger “What’s new” page.  This page has great links to more information.

I’ve spent a good chunk of my day working on writing the message that PSS will send to customers who contact us about the mandatory upgrade.  I’ve gotten lots of great support from folks all over the company on putting this together.

If you contact PSS here’s what the initial response will be:

    Ooopppsss!… sorry about that…i wrote my message in the wrong place…i meant to say…What if I dont have a pentium processor and therefore cant download MSN Messenger 6.2 onto my computer…am i just supposed to suffer?…well i would just like to ask the MSN MESSENGER team to re-allow the use of the earlier versions of MSN…PLEASE?!

    I don\’t think this is a complete waste of time and that if you are going to make software that people are going to rely on and use daily…then you should check it before you allow it to be downloaded onto users computers. But above all, MSN Messenger is a great program…but please give us back the use of 6.0 and so on…for those of us that can\’t download the newer versions!
