I have an exchange 2007 sp1 server with rollup 5 installed that has the hub, casand mailbox role all on one machine. When I run test-outlookwebservices to verify my setup is working, test-outlookwebservices crashes part of the way through after displaying the following: [PS] C:\Windows\System32>test-outlookwebservices | fl Id : 1003Type : InformationMessage : About to test AutoDiscover with the e-mail address ex2007test@mydomain.com Id : 1007Type : InformationMessage : Testing server myserver.mydomain.local with the published name https:/ /myserver.mydomain.local/EWS/Exchange.asmx & https://myserver.mydomain.com/ /EWS/Exchange.asmx.

ErrorReportingEnabled: False Is there anyway to figure out what is causing test-outlookwebservices to crash?When I test the autodiscovery service from a machine with Outlook 2007 on it, it reports back that everything has passed.Steve

Hi Steve,This looks know issue with .Net and Exchange 2007 and it was reported here.https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=363175&wa=wsignin1.0You need to apply updates of .Net according to version you have installed on Exchange server.Similar thread you like to go through...http://social.technet.microsoft.com/forums/en-US/exchangesvrclients/thread/7dfdbc80-8a65-447a-be38-3f4ec5379927/#page:2An update for the .NET Framework 3.5 Service Pack 1 is availablehttp://support.microsoft.com/default.aspx/kb/959209Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

For your reference:Outlook 2007 crashes after you install a package that contains the .NET Framework 3.5 with SP1 and the .NET Framework 2.0 with SP2 on an Exchange 2007 Client Access server http://support.microsoft.com/kb/958934 Regards,Xiu

Thank you. This solved the problem that we were having!Steve

This problem exhibits itself on Exchange 2010 as well - even after the application of the above fixes.Does anyone have other ideas?
