I'm currently working with Microsoft on an Issue but was hoping a few other seasoned IT staff may know the answer to this. Our Exchange server (OS W2K3 SP1 + Exchange SP2) has Exchange message delivery default limits on sending and receiving size currently set to 10240KB. Our connector settings and SMTP settings are unrestricted. We have a few specific users that we've set the global settings to be overridden at the per user level in AD to something higher than the general default limits - these would be administrators and the like that may need to send and receive larger emails. Based on the following KB, it was our understanding that the per user overrides should trump the global setting and therefore it should allow email larger than 10MB be delivered to administrative staff. It doesn't seem to and that is our core issue. I am informed that this used to work. Articles in reference:

That stated, can someone confirm if you can set up general restrictions on incoming mail and then tweak the few users that should be exceptions to be allowed the option of receiving larger emails than the default? My alternative is to fill in restrictions on every user - but that seems more complicated than it should be.
