Does OWA work?

Make sure all of the Exchange services are started.

I had a case once where the RPC Client Access Service wasn't started.

What about other versions of Outlook?

<div>
Outlook 2007 and Outlook 2013 work perfectly fine. &nbsp;OWA works perfectly fine. &nbsp;Outlook 2010 has been fully patched. &nbsp;We have changed the authentication from basic to NTLM, to negotiate, none of them work. &nbsp;Only Outlook 2010 has the problem.

Hello,<br />
<br />
Which operating systems are running your Ol2010 ?<br />
<br />
This error could be displayed if the correct certificate need for RPC/ HTTPS is not present on the windows client with outlook 2010<br />
<br />
Which certificates did you configure on your Exchange 2013 to use for HTTPS and outlook Anywhere ? <br />
The accurate certificate must be installed on the Windows Client ( PKI Root certificate or Exchange Self Signed )

I upgraded our exchange server to 2013 and now I cannot get Outlook 2010 to connect. I have all the latest SP and updates applied but it hasn't helped. Any ideas?<br />
