Addressing 'Invalid SASL Argument' Errors in Email Importing

When you troubleshoot issues in which the system is not importing email from Google® email accounts after upgrading to WHMCS 8.6 and modifying the support department settings, you may see an invalid SASL argument error:

last request failed: invalid SASL argument

The Mail Import test failed: Oauth2 auth failed, BAD Invalid SASL argument.

Some of the required information for POP3 email importing via the Google OAuth2 authentication method is missing.

Execute the following MySQL® query against your WHMCS database. You can do this using the SQL tab in phpMyAdmin:

UPDATE tblticketdepartments SET login = 'support@example.com' WHERE name = 'Name of Department'; 

• Replace support@example.com with the email address of the Google mailbox.
• Replace Name of Department with the name of the support department.

The End! should you have any inquiries, we encourage you to reach out to the Vercaa Support Center without hesitation.
