Email diagnostics and troubleshooting inbound and outbound email

The Diagnostics and Connection page displays information about the current state of your email configuration. This page includes status on email properties, scheduled jobs, and email account connections that affect how your instance receives and sends email.

Email diagnostics

Email diagnostic information can help you identify problems with inbound or outbound email. For example, if your instance is not receiving inbound emails, use email diagnostics to review items that might affect inbound emails, such as the email connection status and email reader scheduled job.

Navigate to the Diagnostics and Connection page from either of these modules:
  • System Mailboxes > Email Diagnostics
  • System Diagnostics > Email Diagnostics
