Outlook prompts for credentials only on one conference room PC

Scenario

A conference room workstation keeps prompting for credentials in Outlook while the same account works elsewhere.

Recommended Resolution Path

1. Review stored credentials, Office activation state, and Windows Web Account Manager tokens on that PC.
2. Check date, time, and trusted root certificate health on the device.
3. Test sign-in to webmail and another Office app to isolate whether the problem is Outlook-specific.
4. If the room PC is shared, inspect local profile sprawl or kiosk hardening that may be blocking modern auth.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
