I can successfully sign into my Microsoft account and access OneDrive and account.microsoft.com. Outlook Mail, Outlook Calendar, and Outlook Mobile all fail with StartupData HTTP 500 errors. Here is the error message I am getting when going to outlook.live.com and calendar.live.com
UTC: 2026-08-31T16:34:39.475Z
Request ID: f2de63c7-c87e-9812-96f6-bf2f23260d0c
Client ID: EAEA7735FCE24A819790500040B9B7FE
Session ID: 292b244d-6266-4e0b-9976-e056000e4d1f
Error Source: StartupData
Status: 500

Any help would be appreciated. Unable to get to human support and online support tells me that outlook is fine.
Regards
Chris
