Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ExternalIPAddress

The ExternalIPAddress parameter specifies the IP address used in the Received message header field for every message that travels through the Edge Transport server or the Transport service on a Mailbox server. The IP address in the Received header field is used for hop count and routing loop detection. The IP address specified by the ExternalIPAddress parameter overrides the external network adapter's actual IP address. Typically, you would want to set the value of the ExternalIPAddress parameter to match the value of your domain's public MX record. The default value of the ExternalIPAddress parameter is blank. This means the actual IP address of the external network adapter is used in the Received header field.

-MessageTrackingLogMaxDirectorySize

The MessageTrackingLogMaxDirectorySize parameter specifies the maximum size of the message tracking log directory. When the maximum directory size is reached, the server deletes the oldest log files first.

The maximum size of the message tracking log directory is calculated as the total size of all log files that have the same name prefix. Other files that don't follow the name prefix convention aren't counted in the total directory size calculation. Renaming old log files or copying other files into the message tracking log directory could cause the directory to exceed its specified maximum size.

For Mailbox servers, the maximum size of the message tracking log directory isn't the specified maximum size because the message tracking log files generated by the Transport service and the Mailbox Transport service have different name prefixes. Message tracking log files for the Transport service or for Edge Transport servers begin with the name prefix MSGTRK. Message tracking log files for the Mailbox Transport service begin with the name prefix MSGTRKM. For Mailbox servers, the maximum size of the message tracking log directory is two times the specified value.

-UseDowngradedExchangeServerAuth

The UseDowngradedExchangeServerAuth parameter specifies whether the Generic Security Services application programming interface (GSSAPI) authentication method is used on connections where Transport Layer Security (TLS) is disabled.

Normally, TLS is required for connections between the Transport services on Mailbox servers in your organization. On TLS secured connections, Kerberos authentication is used by default. However, there may be scenarios where you need to disable TLS between specific Transport services in your organization. When you do that, you need to set this parameter to $true to provide an alternative authentication method. The default value is $false. You shouldn't set this value to $true unless it's absolutely required.

If you set this parameter to $true, you also need to create a specific Receive connector to service the non-TLS connections. This Receive connector must have remote IP address ranges specified to ensure that it's only used for non-TLS connections. You also must set the SuppressXAnonymousTls attribute of the Receive connector to $true.
