Exchange 2007 microsoft-server-activesync requires credentials internally

Question

We've got a proper DigiCert wildcard certificate which appears to be set up properly on Exchange 2007.

The Microsoft test site https://www.testexchangeconnectivity.com/ passes without any problems as does Test-OwaConnectivity & Test-OutlookWebServices internally.

Our problem is that internal Outlook users keep getting a message asking if they'd allow Autodiscover to configure Outlook and then a popup asking for credentials. If the user ticks a box to allow the autodiscover service to configure Outlook always, they still get the popup every time they open Outlook.

Any ideas?

Answer 1

What type of outlook version are you using? Outlook 2003 works different from Outlook 2007/2010.

Can you please specify the credentials settings for OwaVirtualDirectory and Microsoft-Server-ActiveSync directory.

I would also point out the need of correct InternalUrl and ExternalUrl.

By the way, microsoft-server-activesync is only for mobile devices, not for Outlook clients!
