Exchange 2013 SP1 transport agents issues – KB2938053

After you install Microsoft Exchange Server 2013 Service Pack 1 (SP1) or you upgrade an existing Microsoft Exchange Server 2013 installation to Exchange Server 2013 SP1, third-party or custom-developed transport agents cannot be installed correctly.

Additionally, the Microsoft Exchange Transport service (MSExchangeTransport.exe) cannot start automatically. Specifically, you cannot enable third-party products that rely on transport agents. For example, you cannot enable anti-malware software or custom-developed transport agents.

Products experiencing the issue are:

  • TrendMicro ScanMail
  • McAfee Email Security (GroupShield)
  • Symantec Mail Security for Exchange
  • AVG for Servers
  • ESET Mail Security for Exchange
  • CodeTwo Exchange Rules

This problem occurs because the global assembly cache (GAC) policy configuration files contain invalid XML code.

Microsoft published article about this issue KB2938053 where you can download script which will repair xml files Exchange2013-KB2938053-FixIt.zip.

Exchange 2013 SP1 not accepting emails

After installing SP1 for Microsoft Exchange 2013, you can expect some issues.

One of them is that after applying SP1 your Exchange server will stop accepting inbound emails and connections to port 25.

If you check Event Log, in Applications Log you will find entries with ID 7012 with source MSExchangeFrontEndTransport and with information:

“The service state for frontedn transport is inconsistent. Current state – Inactive. Expected state – Active.”

Using Powershell you can check state of this component:

Get-ServerComponentState servername01 -Component FrontendTransport

But you will see that this component is Active.

Also you can test inbound external email using Microsoft Remove Connectivity Analyzer, where you can find information about connection error to TCP port 25.

To resolve this issue you need to restart Microsoft Exchange Frontend Transport service.

You can do this using Powershell:

Restart-Service MSExchangeFrontendTransport

or just restart service in Services.msc.

When you do this, your server should now accept connections to port 25, and also you shouldn’t see warnings in Application Log.
