Hi

I’m having an issue with a new O365 account - I added it successfully, 
I got the authentication prompt via web browser and I can receive 
without issue.

Yet I get this error for SMTP

	4.5.11 Too many authentication errors (4) on this connection, closing 
transmission channel. [ZR0P278CA0144.CHEP278.PROD.OUTLOOK.COM]”.

Are IMAP and SMTP not using the same credential ?

Any pointer most welcome !
