Hello,

We have a NT4 PDC that runs Exchange 5.5. We currently have our Web
server on a Windows 2000 server running OWA 5.5.

We want to upgrade our Web server to Windows 2003 which basically takes
IIS5 to IIS6. What we don't know is if OWA 5.5 will even run on IIS6
(worker process mode or IIS5 isolation mode)

If OWA5.5 will not run or we must run in the older IIS5 isolation mode can
we install a newer OWA version to work with the Exchange 5.5???

We own the newer Exchange version, but we don't plan to install it until
we make our switch from the NT4 Domain to the Active Directory 2003.

I look forward to your response.

Greg

I don't recall that OWA 5.5 will run on 2003 server but never thought to use
IIS in isolation mode. For what it's worth, 5.5 is not supported on Windows
2003 server at all so this is likely an area that you'd be walking down
alone meaning that you'd have to do the development and would not be able to
expect support at any time. Would it work? It's possible but not likely.

As for using a newer version of OWA with 5.5, the answer to that is no. The
newer versions use WebDAV/HTTP to access the data store. 5.5 doesn't speak
WebDAV. 5.5 OWA is the only version of OWA that will work with Exchange
5.5.

Thanks for the reply... The more research I did the more I realized it
wasn't going to work.

Thanks again.
