Obtaining an Authorization Code

When MHA performs a failover or stops working due to an error, you can execute send_report to obtain the failover report by an email. In this way, users can learn about the current database status in time. In this solution, emails are sent through SMTP. You need to log in to the mailbox to enable SMTP. In addition, an independent password or authorization code is required for sending emails. Perform the following operations in this section to obtain the authorization code. The Outlook mailbox is used as an example.

1. Log in to your mailbox. Click the Settings icon in the upper right corner and click View all Outlook settings.
