If you're getting this error when sending out email, please double check your email settings by doing the following steps:
For outlook
- Click Tools then Account Settings...
- Select the email account and click Change
- Click on "More settings"
- Select "Outgoing Server" tab
- Tick "My outgoing server (SMTP) requires authentication"
- Select "Use same settings as my incoming email server"
- Click Ok
- Press Next
- Lastly, press Finish
For MAC/iOS - make sure you have outgoing mail authentication turned ON and that BOTH the user name and password are entered. iOS says you don't need the password - YOU DO.
Once these steps are done, try to send the email again. Please open a ticket if the problem persists.
