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 have now gone 3 weeks without getting the 1001 error, it only occurs when users change their password and the next day it is working fine again. Although today I had to go through one of our steps with someone who changed their password yesterday and after deleting the broker pluggin folder it was fine, I would just put it down as being temperamental.

Same errors with Version 2210 Build 16.0.15726.20188. :(

Not 1001 but "Password required" and no login popup.

As much as I would like to be optimistic by this, I reviewed the release notes and it didn't indicate anything regarding error 1001. I hope they acknowledge the issue properly and they actually mention it in their release notes if it's been resolved.

My ticket with Microsoft is still being discussed internally. I have not received any updates since 2 weeks ago when I provided MSOAID logs as per their request.

Hi Create a new config.xml with your need, important Version keep 16.0.16026.20200.

<Configuration>
```
&lt;Add OfficeClientEdition="64" Channel="Current" Version="16.0.16026.20200"&gt; 

	&lt;Product ID="O365ProPlusRetail"&gt; 

		&lt;Language ID="en-us" /&gt; 

		&lt;ExcludeApp ID="Access" /&gt; 

		&lt;ExcludeApp ID="Lync" /&gt; 

		&lt;ExcludeApp ID="Publisher" /&gt; 

	&lt;/Product&gt;   

&lt;/Add&gt; 

&lt;Updates Enabled="FALSE" /&gt; 

&lt;Display Level="None" AcceptEULA="TRUE" /&gt; 

&lt;Property Name="AUTOACTIVATE" Value="1" /&gt; 

&lt;Property Name="SharedComputerLicensing" Value="1" /&gt; 
```
</Configuration>

Use setup.exe /download config.xml -> Download Office 365

Use setup.exe /configure config.xml -> Install Office 365

Please follow this Guide https://techlabs.blog/categories/office-365/install-office-365-using-the-office-deployment-tool

As an additional step, I created a GPO for Microsoft Office 365 to disable the Office Update and Hide the Notification and the Button.
