Connector report

The Connector Report displays information about messages that are delivered to and from your Office 365 organization using connectors. You use connectors between your own email servers and Office 365 or your partner's servers and Office 365. The message volume for each connector and the TLS encryption for the connection is available.


For more information, see these topics:

The Mail Flow view shows the volume of messages through the connector for the past week. You can change the date range by selecting Filter where you can increase the range to a maximum of 30 days. The All Connectors view shows all mail flow to and from your Office 365 organization through all connectors. You can select a specific connector by name in the drop down menu.

You can select the TLS usage view from the drop down to see the breakdown of TLS protection for messages through the connector. As with the TLS Overview Report report, this view shows the percentage of the different TLS versions. For TLS 1.0 connections, you really need to get your email server or your partner's server upgraded or fixed to avoid any issues when TLS 1.0 support is eventually deprecated in Office 365. For more information, see Technical reference details about encryption in Office 365.

Insights point to connectors to help draw your attention to potential TLS encryption problems for the connector. The insights are: No TLS is over 25% or TLS 1.0 is above 50%. If you see these insights, you need to investigate your email servers that are associated with the connector, or reach out to your partner organization.
