Frequently Asked Questions

SMTP Account: Error message when sending: An unexpected error occurred (1)
 
This points to an error while authenticating your email account. Try checking the following:
  • The username is wrong/incomplete. For example, iCloud accounts sometimes work with "username" but most times need the whole email address as a log in.
  • The password is wrong.
  • If you're trying TLS, try STARTTLS instead.
  • Maybe your server is using a custom port - though this is unlikely.
If you have a Mail program you use (e.g. Apple Mail) try comparing the outgoing mail settings there and use the same settings in Mail Designer 365. FAQ Image - S_732.png
