Exchange 2003 Message Size Limits

Current message size configuration for Exchange 2003:

Global settings: 25MB
SMTP connector: 10MB

This achieves our main objective of allowing up to 25MB internally, but only 10MB outbound to Internet addresses. (Don't ask why we just can't set everything at 10MB!)

However, we have the additional requirement that a couple of select users need to send attachments larger than 10MB to Internet addresses. (I know they may not go through anyway at that size, but this is the business requirement.) I was hoping to use the per-user settings, but have discovered it only overrides the Global settings, not the SMTP connector.

Is there anyway around this?

You may, if you wish, set up another smtp connector allowing higher limits for a defined address space.
somebody came up with the same question today, see the suggestions

Thanks for that response, its an idea we'd considered, but still leaves us a bit short of the ideal objective to have only certain users being able to send +10MB attachments.


Thanks for the link, but it doesn't solve the problem because the internal limit is greater than the SMTP limit. The linked example are looking for SMTP greater than the default.

Any other suggestions?
Use group membership to control who can send mail through the smtp connectors.
