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 the latest version (32bit) Microsoft® Word voor Microsoft 365 MSO (Versie 2309 Build 16.0.16827.20166) 32 bits ,

    but doesn't make any differance, still getting the errors. Our external IT partner says there more and more cliënts with this problem. Even if they don't use FSLogix, so we can conclude it's not an FSLogix problem as many more are saying in this thread.

    Still having an open ticket with Microsoft, they keep calling me every week to tell they are still looking for a solution/reason why this problem is occuring.

    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.
