Hello,

We encounter an issue with M365 apps (Outlook, Work, Excel) on a specific environment ( Remote Desktop Service)

Sometime, when an user open his application (Outlook for instance) on a RDS, an authentification pop and ask for credentials. If the user enter his credentials, he encounter a 1001 error.

« We encountered an issue [1001] »

https://learn-attachment.microsoft.com/api/attachments/5a947921-955a-4688-ad93-acc305bf77c6?platform=QnA

We already try some step to resolve the issue that help in some case but not all the case, and not defintely for a same user ( Issue occur again) :

  • Clear folder C:\Users*yourusername*\AppData\Local\Microsoft\OneAuth and  C:\Users*yourusername*\AppData\Local\Microsoft\IdentityCache
  • Move the user from 1 TSE server to an other TSE)e
  • Clear FSlogix User profil ( The specific one link to FSLogix Office 365 Container technology )

The main issue is that the error can occur again few day laterfor the same user.

We also generate some log from M365 apps client during the signin process with this link to help : https://learn.microsoft.com/en-us/office/troubleshoot/diagnostic-logs/how-to-enable-office-365-proplus-uls-logging

In the log I find the reference to the 1001 error but the log is a bit complex to understand or analyse.

    I easily see it used as an automated script at user logon, running once. The only thing it doesn't do it deleting computer object in Entra, so there will be it will need to be done by scripting or manually to get rid of those stale entries.

    @JMSA85 Can I just confirm that you're simply just running the WPJCleanUp script on every logon per users. Is that how you've set this up?

    We have this issue on a number of RDP solutions and would love to finally solve it.

    This was my solution:

    Create the following regkey on all RDS session hosts:

    HKLM\SOFTWARE\Policies\Microsoft\Windows\WorkplaceJoin

    DWORD: BlockAADWorkplaceJoin Value: 1

    Remove the FSLogix profile for the users and recreated the FSLogix profile.

    I tried all of the below but non of these resolved the issue

    • Initial Workaround: Deleted two JSON files from the Outlook Appdata user folder, followed by signing out and back in from:
      • C:\Users%username%\AppData\Local\Microsoft\Outlook\16\
      • *** Email address is removed for privacy ***
      • *** Email address is removed for privacy ***
    • Secondary Step: When the initial workaround was inconsistent, we removed the same JSON files along with the 'OneAuth' and 'IdentityCache' folders, then repeated the sign-out/in the process:
      • C:\Users%username%\AppData\Local\Microsoft\OneAuth\
      • C:\Users%username%\AppData\Local\Microsoft\IdentityCache\
    • Further Measures: If the previous actions failed, as extensively discussed in this thread, we signed the user out, deleted the 'Microsoft.AAD.BrokerPlugin' folder from the User Profile Disk, and then reconnected to the RDS.
    • Last Resort: Attempted to recreate the user session.

    I then added the below regkeys and removed any entries within Microsoft Entra dating back before 2020 and the issue was resolved

    We are now investigating a solution that involves blocking the 'WorkplaceJoined' option by adding the following registry keys:

    • HKLM\SOFTWARE\Policies\Microsoft\Windows\WorkplaceJoin
      • DWORD: BlockAADWorkplaceJoin Value: 1
    • HKLM\SOFTWARE\Policies\Microsoft\Windows\WorkplaceJoin
      • DWORD: AutoWorkplaceJoin Value: 0

    This was on 2 x RDS servers, no reboot was required. This fixed it for all users after around 30 minutes of adding the rekeys

    Buenos días.

    Mismo problema, aun sin solución aparente de momento.

    Aporto datos:

    Hemos conseguido una solución algo CUTRE, copiar el contenido de la carpeta "C:\Users%username%\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AC" con una directiva al inicio de sesión, a una carpeta de red accesible.

    Parece que no copia el contenido de esa carpeta en entornos RDS con granja, como es nuestro caso.

    robocopy "C:\Users%username%\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AC" "\SRVNAME\ac%username%\AC" *.* /e /s /xo /COPY:DATSO

    robocopy "\SRVNAME\ac%username%\AC" "C:\Users%username%\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AC" *.* /e /IM /COPY:DATSO

    No es una solución que me guste, pero ha conseguido igualmente miminizar los errores, tanto de 1001, como de petición de password constante en el entorno de RDS en Granja.

    Saludos.
