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.

    Dear ARGUAIROLLES Florian,

    Good day! Thank you for posting to Microsoft Community. We are happy to help you.

    Based on your description, we understand that this behavior occurs in a specific user, and that you have tried to fix this phenomenon and still encounter this issue.

    Due to the special nature of your environment, it is difficult for us to simulate your environment for testing, in order to troubleshoot whether it is related to the environment and to save your time, we kindly recommended you can raise a service request in Microsoft 365 admin center, which the support there has the related permission and resource to help you. They can also remotely assist you in analyzing your app activity logs.

    Thanks for your cooperation.

    Sincerely,

    Tin | Microsoft Community Moderator

    Hello Tin,

    It is not related to a specific user.

    Issue occur on different users, different TSE server.

    Today, we had few cases that we resolved by reset the FSLogix Office Container of the user but it is still unclear why it occured. If it can help, this container contains these folders :

    May be related to an authentification / identity token that expired and does not succeed to renew ?

    I will try the M365 admin online support, see if it can help.

    I have the exact same issue. Only have this with this client and not with any other of our RDS deployments.

    Server 2019, fslogix latest version, load balancing 2 RDS servers. Each extra added mailbox gives the error 1001. Then I have to remove the AADbrokerPlugin folder in appdata\local\packages and sign-out/sign-in to fix it. Only then they get the prompt so sign-in into the other mailboxes.

    I have disabled the (default setting now) for the roamingidentity parameter.

    Both RDS servers are also AzureAD joined (hybrid) and SSO has been enabled.

    Hello Shane,

    Thx for your answer.

    We will try on the next case to remove "AADbrokerPlugin folder in appdata\local\packages" and see if it works .

    Can you detail the "disabled the (default setting now) for the roamingidentity parameter", at which level ?

    Thanks !
