I'm having some issues related to OWA/Exchange/IIS that arose after running Exchange 2010 SP2 and after some digging around I haven't been able to resolve this. To preface, OWA was functioning properly before the update.
When I attempt to access OWA (internally or externally), the page displays without issue. Once I attempt to login with the appropriate credentials, the browser will spin its wheels before eventually resulting in "IE cannot display the webpage."
From what I'm reading this is an ASP issue with IIS; which I don't doubt, but I'm very hesitant to break Exchange. I can take this to an IIS forum if needed but I figured it was the Exchange SP2 deploy that caused it, so here I am.
I'm also thinking of tryin gto go with Exchange SP2 Rollups to see if that can resolve anything, but don't want to compound this issue by any means.
