asked on Can Ex2010 OWA only be dropped into EX2007 environment?
I have the install media and license for Exchange 2010 but I have put off the task of upgrading from Ex2007. In the meantime, can I drop the 2010 OWA-related code into my Ex2007 environment to replace the existing OWA and take advantage of new OWA 2010 features? I see in 2007 IIS where the owa code is - in fact I seem to have several versions of scripts 8.2.xx and 8.3.xx. Is this doable and it is relatively low-risk? I could use an actual procedure if so. Existing server is 2008 R2.

That's not really a good idea. OWA for 2010 has some functional differences from 2007 that rely on the interaction between Exchange 2010 CAS and MBX servers to operate. If you drop in the OWA code for 2010 into the OWA site for a 2007 CAS server, you can expect a lot of breakage.

Thank you both - it seems like I need to wait until I am ready to upgrade everything. I will split the points. Hello, Lee - we still have owa-pda around here somewhere! --Dale
