I released this tool yesterday, but I quickly decided to publish a small update. This version adds new functionality to address some existing limitations, especially related to character encoding.
The Portuguese language includes many accented characters. In the previous version, imported or read files displayed all accented letters as question marks. This behavior clearly indicated an encoding issue.
Once again, the Microsoft Message Queuing Testing Tool is a simple utility that allows you to test sending files to Microsoft Message Queuing (MSMQ). Its purpose is to help validate whether other applications are reading the messages correctly.
I am using this tool to send messages to a queue that is consumed by BizTalk Server.
📝 One-Minute Brief
This post announces an updated version of the Microsoft Message Queuing Testing Tool, addressing character encoding limitations found in the initial release. Version 2.0 improves message labeling, file import handling, and allows selecting the code page identifier, making MSMQ testing more reliable for BizTalk and integration scenarios.
Release Notes
Version 2.0 brings:
- Improvements in the Message Label auto-fill.
- Improvements in the “Import Message File” functionality, with better control of the encoder associated with the file.
- Add the ability to choose the code page identifier.

Hope you enjoy it.

Hi, I’m using the Test messaging tool to send a message from a text file. When I try to send, it appears in the queue but has extra characters added – causing the message to fail (my message should start with MSH). I’ve tried different combinations of coding (UTF-8, ANSI, etc) –
