Hi there,
Hopefully somebody can help because I really can't see what's going on here.
- The maximum receive size is set to 100MB in all my receive connectors.
- The maximum send size is set to unlimited in my send connector.
- Mailboxes do not have any specific limits set
- No mail rules are set up
- I have no limits set anywhere else
- I followed a post that suggested editing limits using ADSI editor here and the values were indeed set to 10MB. I changed it to 200MB, and rebooted the server
I can send attachments between Exchange accounts that are larger than 10MB, and I can also receive attachements from external addresses that are larger than 10MB. But whenever I try to send one externally, I get the following error:
This message wasn't delivered to anyone because it's too large. The limit is 9 MB. This message is 23 MB.

This message is larger than the size limit for messages. Please make it smaller and try sending it again.
