Hello

When applying the Office 365 settings to the SMTP mail settings in Business Central we are experiencing an error upon sending a test mail:

MailKit.Net.Smtp.SmtpClient.Authenticate failed with message VXNlcm5hbWU6

How can we read some more information on this error?

Thanks

Hello,

This is a base64 encoded string asking you for your username and password:

www.ndchost.com/.../test-smtp-auth-telnet

Or:

github.com/.../686

Do you have a screenshot of the SMTP server (please ensure you blur the mail address).

Thanks.
