We have Exchange 2003 partially migrated over to Exchange 2010. When an external user sends a file they receive an error report from our exchange, saying the limit is 10MB. I have gone through the settings Here and changed them to 50MB but I still receive the message from a test email from googlemail. Is there any other settings I may have missed or need to try.

For Exchange 2007 and 2010, I always go to this article titled, "Setting Message Size Limits in Exchange 2010 and Exchange 2007." Here is the link:
