All E-mails with attachment bigger than 10MB are being reject by E-mail server of my company. When I try to send mail from my Gmail, to my work account I get following message:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 552 552 5.3.4 Message size exceeds fixed maximum message size (state 17).
In Exchange Management Console of our server, I set maximum receive size as show in following picture, but E-mails are still blocked.

Also in SERVER Configuration->Hub Transport->My Receive Connector->Maximum Message Size I set value 20200, but still no results.
