EX16-MB-000460 - The Exchange Outbound Connection Timeout must be 10 minutes or less.

Warning! Audit Deprecated

This audit has been deprecated and will be removed in a future update.

Information

Email system availability depends in part on best practice strategies for setting tuning configurations. This configuration controls the number of idle minutes before the connection is dropped. It works in conjunction with the Maximum Outbound Connections Count setting.

Connections, once established, may incur delays in message transfer. The default of 10 minutes is a reasonable window in which to resume activities without maintaining idle connections for excessive intervals. If the timeout period is too long, idle connections may be maintained for unnecessarily long time periods, preventing new connections from being established. Sluggish connectivity increases the risk of lost data. A value of '10' or less is optimal.

Solution

Update the EDSP to specify the 'ConnectionInactivityTimeOut' value.

Open the Exchange Management Shell and enter the following command:

Set-SendConnector -Identity <'IdentityName'> -ConnectionInactivityTimeOut 00:10:00

Note: The <IdentityName> value must be in single quotes.

or

Enter the value as identified by the EDSP that has obtained a signoff with risk acceptance.
