I'm desperate for help with this issue, as I've got a number of people asking why OMA isn't working. I'm running SBS 2003 with exchange and sharepoint (including v3). I've checked that all the IIS settings and HTTP protocol settings reconcile with all KB articles that I've come accross, as far as I'm aware (disable Forms Based Authentication, no SSL, correct authentication on all virtual sites etc.). I'm getting the following error in event viewer, which I believe is some sort of issue with .NET 1.1?
When I navigate to http://server/oma
I get a blank page with the following message:
A System error has occurred while processing your request. Please try again. If the problem persists, contact your administrator.
OWA works perfectly when using https, however a few errors are displayed on the page when http, although it's still operational. I'm assuming that it's ok for companyweb and default web site to operate through the same port? The IP address of companyweb is defined as the server, however default web site is [All Unassigned].
I didn't set this server up, so not quite sure what's been done. Unfortunately a clean install is not an option.
Any suggestions would be much appreciated, it's driving me mad!
