I have an Exchange 2013 with latest CU2 update installed. Everything is working fine except autodiscover. Im testing the autodiscover through Microsoft remote connectivity analyzer and it passes all tests except the last that says "
Testing HTTP Authentication Methods for URL https://firstname.lastname@example.org:6002
The HTTP authentication test failed.
A Web exception occurred because an HTTP 501 - NotImplemented response was received from Unknown.
Elapsed Time: 610 ms.
Any ideas ?
