I am working in an MS Exchange 2003 environment and my situation is as follows:
Within my organization all users currently have a 10MB limit on sending and receiving size limits.
What I would like to do is set the inbound (external) size limit for just a couple of people to a larger size. So for instance I would have almost all users with a 10MB limit, and them just two with a 20MB receive size limit.
I have increased the size limit on the SMTP virtual server to 20MB. On the individual accounts that I want to increase the limit on I have change their settings from default to the larger size.
The problem I run into is that the default size limit set under Global settings  message delivery  properties  defaults is applied to all inbound internet mail. So the messages will never reach the user.
Is there a way to allow larger email sizes for the “Internet user” so that inbound emails from the internet won’t have the default applied to them until the size is actually checked against the final destination’s limits? If not is there a way to easily set all the current users individual limits to 10MB (the current default) so that I can set the global default to a larger size which will allow the internet emails to pass? Or is there a better way that I haven’t thought of?
