Hello, We have just installed a new 2003 Exchange Advanced server. The problem being that we cannot send any attachments that are 10Mb or more. I have looked at all of our settings and there appear to be no restrictions on the size for the email being sent out. We are also running Norton Enterprise on the server with Symantec Mail security for Exchange. The Error reads: Microsoft Word The message being sent exceeds the message size established to this user. Any suggestion? Thanks Ken
