Hi @Michael Seaney,
Thank you for providing information.
Based on the error details you shared, I have shared troubleshooting steps that I felt will help resolve the issue you reported.
- Ensure that the Windows 11 Enterprise multi-session host is up to date with the latest patches and updates.
- As you mentioned, FSLogix 2.9.8884.27471 requires a sign-in to Outlook on every login. Try disabling modern authentication in FSLogix to see if it resolves the issue. You can do this by setting the EnableModernAuth registry key to 0.
- Check the Outlook settings to see if there are any specific configurations that might be causing the issue. Try resetting Outlook to its default settings or creating a new Outlook profile.
- Although you've disabled hardware acceleration in most apps, try disabling it specifically for Outlook to see if it makes a difference.
If you have any further queries, do let us know.
