Particularities with Outlook 2019


There is a change with the Autodiscoverprocess on Outlook 2019, which leads to the query of the Office365 Account first.
This change of order creates a connection error with Outlook 2019 and the central Mailsystem of the RWTH Aachen.

In order to solve the issue, you have to configurate the Registry Key on your workplace with the following codeblock:

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover] "ExcludeExplicitO365Endpoint"=dword:00000001
