How to turn off Autodiscover Warning in Outlook 2010/2013/2016/2019

Warnung: Das Konto wurde fuer die Einstellung auf die Website umgeleitet

https://support.microsoft.com/en-us/help/2480582/how-to-suppress-the-autodiscover-redirect-warning-in-outlook

A little bit more explained than in the Microsoft KB and with a check THAT if you ONLY set the Registry key if the OFFICE Version is installed. During Migrations you could otherwise run into trouble if this key re-applies just the time you migrate to next office version.

We have:

Autodiscover.butsch.ch    (Exchange Server Autodiscover DNS entries)

mail.butsch.ch             (Exchange Server)

This is what we don’t want and we talk about. NOT the Certificate Warning that it something else which should solved the correct way and understood.

See as example our entry for SPLIT DNS and Certs: https://www.butsch.ch/post/Exchange-200720102013-with-SPLIT-DNS-and-ONE-single-Certificate.aspx
