Outlook 365 app error 1001 on RDS environment ( FSLogix)

Anonymous

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.

We use regular user profile disks stored on a file share VM as mentioned in an earier reply.

We now only get calls about the Outlook 1001 error after a user changes their domain logon password. We use Azure AD Sync.

To fix it for the user we do the following:
1. Sign out of RDS fully
2. Re-open Outlook and try clicking in the bottom right where it will either say disconnected or need password. Click that and follow through what it says, multiple times if necessary (it goes through the MFA/password entry process multiple times).
3. If the 1001 error pops up close Outlook again and re-open it.

In the analyses we were able to do, we noticed that the users had 1 or more RDS servers on which they had no problems, the latter had a record in Entra.

As long as users were connecting to these machines, there was no problem, but as soon as they changed "Error 1001".

I had found a piece of information that said that registering RDS servers in Entra didn't work very well, so we decided to do the tests below, rather than registering all servers for each user.

So we tested the following scenarios:

1 – just the change in the registry key : no change

2 – then update the applications (with scenario 1) : no change

3 – Just delete the Entra record without modifying the profile and the ODFC : the problem comes back

4 – Deletion of the Entra record and deletion of only the Fslogix profile : this worked the same day and as soon as the user changed the reference server the error reappeared

5 - Deleting the Entra record and deleting only the profile and fslogix ODFC : and since then no more worries

So i read into that the deleting FSLOGIX profiles which would then remove any kind of roaming error and start it fresh again. Did you get any errors with JUST changing the registry key and deleting in Entra or did you also remove the FSLOGIX profile each time ? Be interesting to see if anyone has fixed theirs with JUST the Registry and Entra fix ?

Hello

In our case, 4 RDS 2022 environment, FSLOGIX.

We did all the Office updates version 2312, Fslogix 2.9.8612.60056.

Then we changed the registry keys

[HKLM\SOFTWARE\Policies\Microsoft\Windows\WorkplaceJoin] "BlockAADWorkplaceJoin"=dword:00000001

Then, in Entra, we went to delete the records of the users concerned on the RDS workstations

After that, log off the user and delete the Fslogix profiles and odfc

Then reconfiguration of the user's environment on the RDS

And since no more error 1001 among our users (while we had between 8 and 12 calls per day out of 70 people)

This was happening for users with and without other mailboxes so there was nothing definitive for us in this respect. This only thing we can say with any certainty (at least in our environment) is that 2 separate 2022 RDS servers with 365 Apps for Business on that are not using FSLOGIX (or UPD) and are not covered by an RDS broker (although i don't think that matters) have never had a single issue but the 4 RDS servers that we use FSLOGIX on have regardless of which version of Office we put on have loads of issues. Also with certainty that the users that have had this issue and that we've bounced between the FSLOGIX rds servers without success then ALL work when put onto the 2 independent servers so again the same version of Outlook, same user, same workplace join etc on both environments but only have an issue on the ones with roaming profiles (i.e. FSLOGIX and possible UPD if we had them).

The fact I then disable Roaming Identities on the FSLOGIX servers and the problem goes on all the accounts in one go makes me think that this is our fix in that when we've had this problem with say User A we would then bounce them from Server A onto Server B and then sometimes the issue would go away but sometimes not makes me think that the mechanics to move identities between servers isn't working ALL the time and so getting sporadic results.

I'm not sure if anyone on here has had these issues when using local profiles on the RDS servers (so without any roaming profiles setup) have they ?

EDIT: Just noticed on AFABIA's post they stated to enable roamidentity but it was disabling it that i think worked for us:

Error “Something Went Wrong [1001]” signing in to Microsoft 365 Desktop Applications - Microsoft Support

It was scenario 2 that i followed where they said "user profile data is being roamed and that can cause identity and authentication data components to be in a bad state" and that seems to fit in with our scenario (we also have stopped our appdata being redirected through folder redirection GPO a while ago)
