552 5.3.4 Message size exceeds fixed maximum message size

Have you run into this error on a Exchange 2007 server, or a SBS 2008 box? While working on a clients network this week, I ran into it. After doing some research, a simple modification needs to be made. Open up a Powershell and use the command Set-ReceieveConnector –identity “Default [servername]” –maxmessagesize 20MB

This will increase the size to 20MB.


You also may want to increase the Message size limits for the entire server. If you take a look at Technet , you can set the connector limits, server limits as well as user limits.


Here is another Blog I came across with the same information as well:
