I have recently got a new computer with windows 10 and I having a problem with autodiscover with Windows 10, outlook 2013, and Exchange 2010. Basically, my scheduling assistant, out of office, and autodiscover are not working. Scheduling Assistant shows everyone greyed out, Out of office is unable to contact the server, autodiscover fails all attempts when testing. I do have other users that have windows 10 that are running outlook 2013 with no issues.
I have tried all these features in OWA and everything works without issue.
I am getting the following error in the event logs of the exchange server.
Inbound authentication failed with error LogonDenied for Receive connector Default EXCH1. The authentication mechanism is Ntlm. The source IP address of the client who tried to authenticate to Microsoft Exchange is (192.168..) which is my IP address.
Autodiscover fails with (0x80072ef3) error
I have tried rebuilding my profile and that has made no difference. I have also tried reinstalling Outlook. I do have a windows 7 machine running outlook 2013 and everything is working.
Not sure where to go from here.
