The reports in the Apple forums describe failed authentication when trying to add Outlook.com, Hotmail, or Live accounts to Mail. Errors range from “Authentication Failed” to “Unable to verify account name or password.”
So far, iCloud, Gmail, and Microsoft 365 Exchange accounts appear unaffected. None of the staffers at AppleInsider have been able to replicate the bug either.
