Here's a statement from MS regarding Outlook and Exchange 5.5.
"Microsoft continuously strives to provide a consistent and predictable
end-of-life-cycle experience for all of its products. In accordance with
standard Microsoft life-cycle policies Exchange 5.5 ended extended
life-cycle support on January 10th, 2006. As a result, Outlook 2007 will
not support Exchange 5.5. Because neither the Outlook or Exchange team is
supporting this combination we will not discover and/or fix issues that crop
up as the result of innovations in both products . Rather than subjecting
customers to potential serious issues like data loss or frequent server
downtime we choose to prevent Outlook from connecting to these older and now
unsupported servers. Our research has shown that there is a relatively
small set of customers who want to upgrade their desktops to the latest and
greatest versions of Office and run server technology as old as Exchange
5.5. There are clearly exceptions but they don't seem to be the norm.

That would only be true if they didn't develop it in the mean time or
analyzed feedback, crash and bug reports. Outlook 2007 has a lot of
structure changes in the mailbox (as for instance categories are now stored
in the mailbox as well, different flagging and categorizing system). If they
can't guarantee a stable environment and using Outlook 2007 against an
Exchange 5.5 server could lead to datacorruption and/or dataloss it's a very
good call to deny the connection. Nothing political about that!

Of course, and I agree with you, you can't stop the inevitable (but our
IT it seems will do everything in their power to delay it as much as
possible). With regards to support from MS, I am just venting as it's
usually a lost cause...; I am just as frustrated with my company's slow
adoption of new technologies...
However, I do hope that some frustrated enthusiast will think of a
solution and post it here; after all, I could not be the only one stuck
with MS Exchange 5.5...!?!; and since everything was working perfectly
just "couple of builds" ago, it seems that this was a result of a
political/business decision rather than technical need...
