Hi,
I have an Outlook email account with multiple aliases. If I send an email from the default outlook account, all is well. However, if I try and send an email from one of the aliases I get the following error.
"Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.office365.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'."
Setting on the alias accocunts are the same as the default.
Sending an email from the alias accounts in Win 10 mail works.
Please advise.
Regards,
Steve
