i saw a similar issue but don't say how he solved, any idea?
Office 365 CCG always ends in ERR Authentication failure: unknown user name or bad password #238
I presume you removed one or more outgoing lines from the proxy log between 2024-04-29 13:13:27
and 2024-04-29 13:13:36
(the submission of the OAuth 2.0 token). Assuming this is present, I would suspect some sort of misconfiguration on the Azure/Entra side.
as you say, the problems was on a MS config.
Thanks,.
