We are in the process of 2003 to 2010 Exchange upgrade so that they coexist in the same environment what I don’t seem to be able to find is as follows.
Question can users still access the old 2003 OWA web page after the upgrade integration of 2010 so we don’t have to configure all mobile devices in one hit, or do all users now have to use the new 2010 OWA webpage? In a nutshell will both OWA servers work side by side?
