Hello, so we tried upgrading our Exchange 2010 with no SP to SP3 last night; however was prompted with an error and the wizard cancelled before the Client Access Role part. After the failure, we did a reboot; however users Outlooks are now unable
to connect to Exchange server and OWA does not work as well. EMC is up and running though and both mailbox as well as public folder databases are mounted properly.
The error I see over and over again in application error logs is:
"The Module DLL C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\auth\exppw.dll failed to load. The data is the error."
Furthermore, whenever we try and log into OWA we get a web.config runtime error. The error we get is: "Description:An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off"."
Does anyone know how to fix this? Thanks in advance for help.
