Outlook Client internal default to RPC over HTTPS not RPC

I have a scenario where all pcs in an environment are defaulting locally to RPC over HTTPS.

I'm assuming this is a function of the web servcies specified in the autodetect configuraiton but can't see to locate the specifics.

What happens is the clients are prompted to log-in repeatedly.
You can manually change the client to NOT connect via HTTPS but it reverts back.

Help is appreciated.

On the Outlook Connection Tab (in the Exchange Proxy Settings window of Outlook), do you have the "On fast networks, connect using HTTP first, then connect using TCP/IP" ticked?

If you do - please untick it then restart Outlook and you should just use TCP/IP not HTTPS to connect to the server.

Checked that long so. I believe a change had to be made in the ems but I can't remember what it is.

I'll review TY. I remember finding a possible solution to this months back but couldn't locate it again.

Bump - still working slowly with client on issue. Supposed to review later this week.

Likely scenario is Autodiscover
