Hi Gunasekar

Thank you for your reply.
Your first option (including save mode) did not work.

In the end I went for the second option, a soft reset to factory settings, making sure to choose "remove installed app's", which got rid of all office applications.

Installing Office 2016 was a bit of a hassle, for anyone reading this:
You have to manually open the x64 Setup file to install office on an ARM machine, the general setup will produce an error every time.

Now everything works fine.
Thanks for the help to everybody

Kind regards

Hello

I am Abdal and I would be glad to help you with your question.

Here is a detailed solution to resolve the issue of Outlook logon with password in combination with WAM Authentication and Office 2019 ProPlus/Server 2019:

Configure modern authentication in Exchange Online or Exchange Server:

Modern authentication is a process that enables identity management for client-server applications, such as Outlook, to use Single Sign-On (SSO) to authenticate to Exchange. You can enable modern authentication in Exchange Online by using the Exchange Admin Center (EAC) or by using the Exchange Management Shell.

Check the credentials prompt settings in the Outlook client:

In the Outlook client, go to File > Options > Account Settings > Account Settings. In the Account Settings window, select the email account and click the Change button. In the Change Account window, make sure that the "Use Cached Exchange Mode" checkbox is not selected.

Reset Windows Credential Manager:

In Windows, you can reset the Windows Credential Manager to remove any cached credentials that may be causing the issue. To do this, go to Control Panel > User Accounts > Credential Manager. Find the entry for the affected email account and remove it.

Update the certificate that the Microsoft AAD Broker Plugin is using:

The Microsoft AAD Broker Plugin may be using an outdated or invalid certificate that is causing the issue. You can update the certificate by downloading the latest version of the plugin from the Microsoft website and installing it on your system.

These are the steps that you can follow to resolve the issue of Outlook logon with password in combination with WAM Authentication and Office 2019 ProPlus/Server 2019.

I hope this information helps.

Regards,

Abdal
