Exchange 2013 and Outlook not authenticating

Hi all,

I've just installed two new Exchange 2013 servers; 1 x mailbox and 1 x CAS. I cannot get Outlook to authenticate to the server. It just keeps asking for credentials and does not progress (even though the credentials are correct).

OWA works fine, and all tests pass on ExRCA. ActiveSync also works fine. I've tried this with Outlook 2013 and Outlook 2010, internal and external to the environment - nothing works here.

I initially had an issue with RPC which required reinstalling. It still doesn't appear to be listening on 6001 after running a netstat, and I know EX2013 relies heavily on RPC so perhaps this is my problem? Can anyone confirm if this is still required in Exchange 2013?

Exchange 2013 uses RPC over HTTP now. So you need to setup Outlook client.

Hi amitkulshrestha,

I've already done that. All is configured as per instructions.

Everything works on TestExchangeConnectivity.com (ExRCA) so it's something to do with authentication, RPC or something along those lines.

This has been resolved. The problem was with the DefaultLoopbackCheck in IIS. Here are the articles I found to help:
