Exchange 2007 message size limits

I can't seem to increase the message size limits in Exchange 2007 on SBS 2008.

I've used the following two lines in the Exchange Management Shell to increase the message size limit to 40MB's and restarted the server but to no avail:

Set-TransportConfig -MaxReceiveSize 40MB -MaxSendSize 40MB

Set-ReceiveConnector “CONNECTOR NAME” -MaxMessageSize 40Mb

When I attempt to send a large message from outside the server it gets rejected.

What am I missing?

Have to set new limits in 3 spots:
Exchange Managemnt console:
1: Organzation Config>Hub Transport> Send Connectors>Windows SBS Internet Send sbs 2008: Set Maximum Message sixe
2: Server config> Mailbox>Mailbox database .Limits (Set limits)
3: server config>Hub Transport> Default SBS2008> Set Maximum Message size.
Restart the information Store under services.
Hope that helps,

It will take upto 2 hours to update these new settings with clients.

If you require additional information there is an excellent article on Technet outlining the procedure, specific to SBS2008:

get-transportconfig command


MaxReceiveSize 40MB
MaxSendSize 40MB

It shows correctly but when I send a 12MB message to the Administrator address it gets rejected.

Try to send the attachment via OWA
You also have to update the message size limitations of the Fax Connector. Don't ask my why, but after upgrading this, it works on my clients SBS Server.

Have a look at the exchange console -> Server Configuration -> Hub-Transport, there you should find the Windows SBS-Fax Sharepoint Receive Connector.

Thanks  Okay tried that.  What about the Windows SBS Internet Receive SERVERNAME connector?
Do I need to change the maximum message size in that as well?
b1dupreeAuthor Commented:
Regarding the previous message, I'm still waiting for the changes to resolve on the SharePoint/Fax connector changes you suggested.  Just want to know about the Windows SBS Internet Receive connector while I wait for it to resolve.
If it's activated, you should also change it.

It was the Fax/SharePoint connector and SBS Internet Receive Connector that did the trick.
