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?
Thanks.

What are your user level and server level limits set at?
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,

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

get-transportconfig command

shows

MaxReceiveSize 40MB
MaxSendSize 40MB

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

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?

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.

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