Outlook asking password
We have several servers, base Proxmox, 2 or 3 VMs : Windows Server 2019 / 2022 : 1 for AD / DNS / ... one for FileServer / SQL the last one for RDS.
RDS using the "basic" install UDP disk on the same server.
Office is installed, Pro or Business version (don't know what is the damn difference).
Each users has a "local" email (office 365 for the client) and another email from government (******@NO-NAME-SERVICE.be). The MFA is ON for gov email and for 50% of email using client name.
On each server, we have SOME with Outlook asking password once a day, or 3 TIMES A DAY, or once every 3 months.
WHY ?
Sometimes we try to add / remove key like (enableAdal, DisableAADWAM, DisableADALaptopWAMOverride), remove entire outlook profile, clear (empty) identification manager, disconnect Office entirely, delete HKCU\Software\Microsoft\Office\16.0\Common\Identity, delete %localappdata%\Microsoft\Office\16.0\Licensing, delete HKCU\Software\Microsoft\Office\16.0\Registration, reboot RDS server, problem still the same..since march I think.
Please, help.
