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've just been reading through the details on the Microsoft support article for this issue (link).

    The details they give under Scenario 2 could be an issue if roaming of the %localappdata% folder is no longer supported:

    1. For those of us that use User Profile Disks (not FSLogix) with multiple RDS session hosts, how do we prevent the %localappdata% from being roamed between session hosts?
    2. If roaming of the %localappdata% is no longer supported, does this effectively mean that using M365 apps inside a multi-session host RDS environment is no longer supported as well?

    Scenario 2:

    In the second scenario the error "Something went wrong [1001]" is caused by user profile management issues.

    In this category of issues, we find that on both VDI and physical devices the user profile data is being roamed and that can cause identity and authentication data components to be in a bad state. 

    Roaming any data under the path %localappdata% is not supported. If you choose to move content under %localappdata%, make sure that the content of the following folders and registry keys never leaves the device under any condition.

    • %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
    • %localappdata%\Packages\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy
    • %localappdata%\Packages<any app package>\AC\TokenBroker
    • %localappdata%\Microsoft\TokenBroker
    • HKEY_CURRENT_USER\SOFTWARE\Microsoft\IdentityCRL
    • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\AAD
    • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WorkplaceJoin

    Roaming of the work account's device certificate is not supported.

    We've only had 12 occurences of the problem this month so far.

    They have all been as a result of users changing their logon passwords. We've not had any of the random occurences. Our RDS environment is running build 16924.20150.

    Commenting to keep this alive, we are having the same issue on an environment that uses FSLogix. Looking for a workaround. We don't use AAD, so the fixes that edited registry keys associated with that are not applicable to us.
