All MS Exchange accounts have failed. Cannot logon for email or calendar
Today, November 12 2026 I lost all access to Microsoft email accounts (through TB) and calendars (through TbSync). Nothing, neither business or personal email accounts, will send or receive email as of this moment. I have checked behavior of software in troubleshoot mode and nothing changes. I have not located an error log in TB. My only indication of a problem is that the windows error console alerts an error "server graph.microsoft.com responded with an error" No other information. It would be nice if the error logs were easily available in TB.
Is there a general conflict between MS graph server and TB??
