Exchange Server 2010Exchange Server 2013Exchange Server 2016PowerShellDescription

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

  • Legacy Exchange Servers (aka Exchange Server 2010)
  • Modern Exchane Servers 
    • Frontend Transport
      or
    • Backend Transport (aka Hub Transport)

For more information read the readme.md file at Github.

Note

You need to adjust the log file path to suit your IT infrastructure. A next releas will contain a more automatic solution.

Examples

# Search legacy Exchange servers SMTP receive log files for the last 4 days and save search results in a single CSV file

.\Get-RemoteSmtpServers.ps1 -Servers SRV01,SRV02 -LegacyExchange -AddDays -4 -ToCsv

Version History

  • 1.0, Initial community release

The latest downloadable build of Exchange Server 2016 Cumulative Update 9 disclosed an information that was previously shown accidently to the public by Greg T. during his breakout session BRK3249 - Modern Authentication for Exchange Server On-Premises at Microsoft Ignite 2017.  

BRK3249 - Modern Authentication for Exchange Server On-Premises

As part of the global harmonization of the product name space of the well established Outlook brand the next release of Exchange Server will be named Outlook Server 2019.

This name change was mentioned originally on this slide:

BRK3249 - Modern Authentication for Exchange Server On-Premises - Leak

 

Give it a thought and you'll realize that this change makes absolute sense as different product names for the same software function distract customers and users. 

  • Outlook
  • Outlook for iOS
  • Outlook for Android
  • Outlook on the web
  • Outlook Server

Another reason for renaming Exchange Server is a new functionality for integrating personal mailbox files (PST). It was and still is a tedious task for administrators to get hold of all those PST files in use by end users. Instead of implementing a complex and data protection safe process to import PST files to the primary users mailbox the new Outlook Server 2019 offers synchronized PST folders. A functionality we've waited for for years.

Two new functions are introduced as part the new modern Outlook Server 2019

  • PST Sync
    Synchronized PST files across DAG member servers
  • Linked PST Files
    New Outlook function to connect to server based PST files advertised by AutoDiscover

How does it work?

  • The  $env:ExchangeInstallPath contains a new folder named PSTSync
    The new folder can be accessed by end users using https://<your OWA FQDN>/PSTSync 
  • Add new subfolder for each user with PST files, assign Owner access to the subfolder and inform the users to upload their PST files using that link
  • The uploaded PST files are automatically renamed andf synchronized between the DAG member servers using PSTSync
  • Exisiting PST files are automatically advertised by AutoDiscover as LinkedPSTFile when queried by a modern Outlook version

The following diagram illustrates the new functionality in a simple Outlook Server 2019 setup:

The new Outlook Server functionality

The following screenshot illustrates the new PSTSync folder and some sample PST file for a user with SAMAccountName JohnDoe

PSTSync Sample for JohnDoe

 

It's good the see that there is a future for a email server product like Exchange Server and that after so many years of cloud only an on-premises only feature got added.

Enjoy the day and Happy Easter!
