Set-MailboxTransportService

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

• Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
• Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

The ConnectivityLogEnabled parameter specifies whether the connectivity log is enabled. The default value is $true.

The ConnectivityLogMaxAge parameter specifies the maximum age for the connectivity log file. Log files older than the specified value are deleted. The default value is 30 days.

To specify a value, enter it as a time span: dd.hh:mm:ss where dd = days, hh = hours, mm = minutes, and ss = seconds.

For example, to specify 25 days for this parameter, use 25.00:00:00. The valid input range for this parameter is from 00:00:00 through 24855.03:14:07. Setting the value of the ConnectivityLogMaxAge parameter to 00:00:00 prevents the automatic removal of connectivity log files because of their age.

The ConnectivityLogMaxDirectorySize parameter specifies the maximum size of all connectivity logs in the connectivity log directory. When a directory reaches its maximum file size, the server deletes the oldest log files first. The default value is 1000 MB.

When you enter a value, qualify the value with one of the following units:

• B (bytes)
• KB (kilobytes)
• MB (megabytes)
• GB (gigabytes)
• TB (terabytes)

Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte.

The value of the ConnectivityLogMaxFileSize parameter must be less than or equal to the value of the ConnectivityLogMaxDirectorySize parameter. The valid input range for either parameter is from 1 through 9223372036854775807 bytes. If you enter a value of unlimited, no size limit is imposed on the connectivity log directory.

The ConnectivityLogMaxFileSize parameter specifies the maximum size of each connectivity log file. When a log file reaches its maximum file size, a new log file is created. The default value is 10 MB.

When you enter a value, qualify the value with one of the following units:

• B (bytes)
• KB (kilobytes)
• MB (megabytes)

The ContentConversionTracingEnabled parameter specifies whether content conversion tracing is enabled. Content conversion tracing captures content conversion failures that occur in the Transport service or in the Mailbox Transport service on the Mailbox server. The default value is $false. Content conversion tracing captures a maximum of 128 MB of content conversion failures. When the 128 MB limit is reached, no more content conversion failures are captured. Content conversion tracing captures the complete contents of email messages to the path specified by the PipelineTracingPath parameter. Make sure that you restrict access to this directory. The permissions required on the directory specified by the PipelineTracingPath parameter are as follows:

• Administrators: Full Control
• Network Service: Full Control

The PipelineTracingEnabled parameter specifies whether to enable pipeline tracing. Pipeline tracing captures message snapshot files that record the changes made to the message by each transport agent configured in the transport service on the server. Pipeline tracing creates verbose log files that accumulate quickly. Pipeline tracing should only be enabled for a short time to provide in-depth diagnostic information that enables you to troubleshoot problems. In addition to troubleshooting, you can use pipeline tracing to validate changes that you make to the configuration of the transport service where you enable pipeline tracing. The default value is $false.

The PipelineTracingPath parameter specifies the location of the pipeline tracing logs. The default location is %ExchangeInstallPath%TransportRoles\Logs\Mailbox\PipelineTracing. The path must be local to the Exchange server.

Setting this parameter to the value $null disables pipeline tracing. However, setting this parameter to $null when the value of the PipelineTracingEnabled attribute is $true generates event log errors. The preferred method to disable pipeline tracing is to use the PipelineTracingEnabled parameter.

Pipeline tracing captures the complete contents of email messages to the path specified by the PipelineTracingPath parameter. Make sure that you restrict access to this directory. The permissions required on the directory specified by the PipelineTracingPath parameter are as follows:

• Administrators: Full Control
• Network Service: Full Control
• System: Full Control

The PipelineTracingSenderAddress parameter specifies the sender email address that invokes pipeline tracing. Only messages from this address generate pipeline tracing output. The address can be either inside or outside the Exchange organization. Depending on your requirements, you may have to set this parameter to different sender addresses and send new messages to start the transport agents or routes that you want to test. The default value of this parameter is $null.

The ReceiveProtocolLogMaxAge parameter specifies the maximum age of a protocol log file for the implicit and invisible mailbox delivery Receive connector in the Mailbox Transport Delivery service. Log files that are older than the specified value are automatically deleted.

To specify a value, enter it as a time span: dd.hh:mm:ss where dd = days, hh = hours, mm = minutes, and ss = seconds.

Valid values are 00:00:00 to 24855.03:14:07. The default value is 30.00:00:00 (30 days).

The value00:00:00 prevents the automatic removal of Receive connector protocol log files because of their age.

This parameter is only meaningful when the MailboxDeliveryConnectorProtocolLoggingLevel parameter is set to the value Verbose.
