Are you using internal CA for issuing certificates to Exchange server, if yes you would need to import the root CA certificate in trusted root certification authorities on every non-domain joined machine.

Hello,<br />
<br />
I am trying to configure Outlook 2013 to connect to an Exchange 2013 on-premise server.<br />
<br />
I go through the wizard process, providing the Name, email address and password.<br />
<br />
As expected, it asks for username and password. &nbsp;The setup wizard process completes as you expect (you get the &quot;congratulations...&quot; messages) and then you are asked to restart Outlook.<br />
<br />
But when I open Outlook again, I get &quot;The connection to Microsoft Exchange is unavailable. &nbsp;Outlook must be online or connected to complete this action&quot;.<br />
<br />
As far as I can see, looking at the account setup details, everything is good...<br />
<br />
As far as OWA goes, all works perfect. &nbsp;As do clients that are on the domain - auto complete works as expected.<br />
<br />
Any ideas?<br />
<br />
Cheers,<br />
