HI,

I'm getting the above error when trying to test a simple Exchange activity to create a task. This particular error occurs when using default authentication - if I switch to typing in my AD credentials (email address & password) it gives me a "The Autodiscover services couldn't be located." message.  In both cases I'm using the "Test URL" link.

The URL seems to be correct (https://<servername>/ews/Exchange.asmx)  and I can paste that into a browser and it loads up an XML response. 

The same messages appear if I try to manually to workflow also, they are not limited to testing.

Any other sufferers?!
