I have a new Exchange 2010 SP3 server. I just found out that we can not make changes in OWA options. We get the error "Sorry! We're having trouble processing your request right now. Please try again in a few minutes."
I have matched up ECP settings in Exchange and in IIS I matched the settings for Authentication and SSL. I have set them according to this link http://technet.microsoft.com/en-us/library/gg247612.aspx
as well as copying those settings from another Exchange 2010 server that does work.
I saw this on one site where they removed and added the virtual directories
"Get-EcpVirtualDirectory | Remove-EcpVirtualDirectory
Get-OwaVirtualDirectory | Remove-OwaVirtualDirectory
I am a little afraid to do this since I may break something else. Is that a safe thing to try
