ActiveSync bug in Exchange 2003 - Warning warning!

November looks like ActiveSync month. First I dropped my Sprint HTC SmartPhone because as a phone it was unusable (despite the fact that sync with Outlook was passable).

But Chris Quinn, one of our pals in the calendaring community, alerts us to a Microsoft KB Article 958781:

Some recurring calendar items disappear from the "Day/Week/Month" view in Outlook when a user uses Exchange ActiveSync on a mobile device to modify a recurring meeting in an Exchange 2003 environment

Much like Snakes on a Plane the title says it all.

But unlike SoaP there's more here to worry about (aside from whether you want the extended edition DVD).

The list of affected files for the fix to this problem includes pretty much all of CDO's associated files PLUS MADFB (the main Free-Busy updater).

This is a scary bunch of sensitive code to be changing all at once. And anything that relies on CDO (Anybody out there have BlackBerry Servers?) could get caught in the backwash.

So our warning to you still on Exchange 2003 is to test this HotFix BEFORE you deploy it if you have anything other than a vanilla Exchange 2003 environment
