Hello,

I have one exchange 2010 in my organization with all the roles-Hub,Cas,MB.(Couldn't find the exchagne 2010 Forum)

suddenly in the middle of life OWA stooped working.

Need help about "The custom error module does not recognize this error" when accesing OWA 2010 (Server 2008 R2) with IIS 7.5

Also trying to open OWA from the iis i get "440 Login Timeout".(apparently it's the same problem).

I read all the KB's in the internet and Tried some of them but none of them helped.941201,917686,3021827 etc.

The most Detailed KB 941201 Refers mostly to exchange 2007 even it's written there that it also refers to 2010(not true).

for example-

For Part 4 is not relevant to exchange 2010 ,all the folders under OWA starts with 14 and not 8.

even though i tried this KB to the end and it didn't helped. 

PLease help anyone !!
