I m trying to add an additional e-mail address to K-9 mail on my android. As I go through the process I get to the outgoing server settings and it says “failed”
Authentication error
The server returned the following message:
Authentication unsuccessful
SmtpClientAuthentication is disabled for the Tenant. Visit Enable or disable SMTP AUTH in Exchange Online | Microsoft Learn for more information.
