Particularities with Outlook 2019


Outlook 2019 has a change in the autodiscover process that leads to the Office365 account being queried first.
This leads to a problem in the connection setup of Outlook 2019 with the central mail system of RWTH Aachen University.

To solve this problem, the following registry key must be set on the workstation:


To do this, call up the Windows app "Registry Editor":

  • Press Windows Button + R and type "regedit"

Navigate to the appropriate path


and set a new DWORD-Value (32bit) "ExcludeExplicitO365Endpoint"

Doubleclick on the DWORD-Value and change the value from 0 to 1
