Hi guys,

I am having trouble testing our connection with OWA which uses Windows SBS 2008. We can successfully use OWA and have been doing for a long time. The reason I am testing is because we are migrating our email (currently on Exchange 2007) to Office 365 with the Cutover Migration - which requires an Outlook Anywhere endpoint. The test fails at this point:

Testing HTTP Authentication Methods for URL https://remote.domain.co.uk/rpc/rpcproxy.dll?mail.domain.co.uk:6002.
	The HTTP authentication test failed.
	Additional Details A Web exception occurred because an HTTP 404 - NotFound response was received from Unknown. Headers received: Content-Length: 0 Date: Wed, 02 Oct 2013 08:59:43 GMT Server: Microsoft-IIS/7.0 X-Powered-By: ASP.NET

Please can anyone assist. 

Many thanks

Aaron

Maybe this is causing your issues:

They say the errors are occasional, whilst mine are constant.
