You might have the requirement to authenticate mobile devices and authorize user access to on-premises Exchange Server mailboxes using a multi-vendor strategy. This blog post focuses on the configuration of a Kemp LoadMaster located in an internal network segment. The Kemp LoadMaster ESP functionality is used to allow ActiveSync connections for members of a dedicated security group only.
This results in the following authentication and authorization endpoints:
The following diagram shows a simplified overview for mobile devices connecting to an on-premises Exchange Server. The perimeter and internal network segments are omitted for simplification reasons.
The following screenshots illustrate a working setup for a virtual service load balancing mobile device connections from MobileIron Sentry to Exchange Server. It's assumed that you've already configured the following:
The SSL Traffic is offloaded and re-encrypted as we need to authenticate the user with ESP. Ensure to select a Cipher Set that does not provide any weak or unsecure cipher suites. In this example I've selected the predefined set BestPractices.
Enable ESP to activate the ESP configuration section. The settings are as follows:
In the Real Servers section you add all member servers of your Exchange Server DAG. Ensure to use the HTTPS protocol the health checks and ensure to query the /Microsoft-Server-ActiveSync/healthcheck.htm document.
Using this configuration you've added your Kemp LoadMaster as an additional authentication endpoint to secure mobile device access to Exchange Server mailboxes.

When migrating to new version of Exchange Servers you must move your internal SMTP relay endpoints. This can be a challeging tasks as application owners mostly ignore your requests for such changes.
You can use the information provided in the receive connector log files to identify remote clients (MTAs / MTUs) connecting to the legacy infrastructure. The assumption is that protocol logging is enabled. You can easily active protocol logging across all receive connector fo a single server using the following EMS PowerShell one-liner:
Get-ReceiveConnector -Server EX01 | Set-ReceiveConnector -ProtocolLoggingLevel Verbose
The scripts searches the log files for the connection's EHLO response which containes the remote name or remote IP-address of the system connecting to the receive connector.
You can either search
For more information read the readme.md file at Github.
You need to adjust the log file path to suit your IT infrastructure. A next releas will contain a more automatic solution.

Today is a wonderful day.
I just received the notification email that I am awarded as a MVP for Office Servers and Services.
Looking forward to interesting times with the other fellow MVPs, MCM and MCSM colleagues.
