ERROR: 'Unknown error' when emailing documents using webmail and 2-factor authentication

How to resolve the email error in Sage 50 Accounts, Sage 50 Payroll or Sage 50 P11D when using Gmail, AOL or Yahoo.

When you try to email documents, sometimes 'Unknown error' appears, and the export fails. Sometimes the following error also appears:

'Error with the address ([email protected]). Unknown error check windows event log for more details.'

---

2-factor authentication (2FA)

This occurs if your email account uses 2-factor authentication. When your software tries to send the email, your software can't authenticate for 2FA, so the send fails.

To work around this issue, create an app password with your email provider.

App password

As a workaround for the providers below, create an app password and use this in your Sage software email settings.

• For Gmail accounts, go to support.google.com
• For AOL accounts, go to help.aol.com
• For Yahoo accounts, go to help.yahoo.com

If you don't use Gmail, AOL or yahoo, follow the troubleshooting email error and issues article.
