Hallo JensOldenburg,



Der neue Sync Client synchronisiert nur die OneDrive for Business Dateien und keine SharePoint Bibliotheken. Vielleicht meinst Du die eigenen …



Was passiert, wenn Du eine Synchronisation vom Cloud startest? Werden dann Deine Anmeldeinformationen akzeptiert?



Hast Du bereits probiert unter: Control Panel > Credential Manager > Windows Credentials > Generic Credentials alle Einträge, die MicrosoftOffice15_Data und MicrosoftOffice16_Data sind zu entfernen?



Freue mich auf Deine Rückmeldung.



Mit freundlichen Grüßen,

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The Microsoft AAD Broker Plugin may be using an outdated or invalid certificate that is causing the issue.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

Title: Multiple credential prompts in the Outlook client

User Impact: Users may receive repeated credential prompts within the Outlook client.

More info: While we're focused on remediation, users that have access to other protocols such as Outlook on the web or mobile devices can access their email without issue. Additionally, customers who are able to use Modern Authentication may enable it to mitigate
impact for affected users. Details on how to enable Modern Authentication can be found here: https://docs.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/enable-or-disable-modern-authentication-in-exchange-online

Current status: We've developed a fix and we're performing extensive validation to confirm that it'll resolve the issue. We expect to begin deployment of the fix within the next 14 hours.

Scope of impact: This issue may affect any user that has service-based search or Focused Inbox. Additionally, this issue only affects users that are attempting to connect to their Outlook Desktop clients via basic authentication.

Start time: Tuesday, May 5, 2020, 6:00 AM (4:00 AM UTC)

Root cause: A recent update to the Exchange Online service contains a code issue that is causing repeated credential prompts for basic authentication users.

Next update by: Thursday, May 7, 2020, 7:00 PM (5:00 PM UTC)
