We have Exchange 2016 server and would like to increase the size of email to 50 MB. We can increase the size at send connector and at transport config to 50 MB with the following commands.

Set-SendConnector <Connector Name> –MaxMessageSize 50MB

Set-TransportConfig –MaxSendSize 50MB –MaxReceiveSize 50MB

However, I am not sure about the receive connector. As there are many receive connectors again one Exchange server so should I have to increase the limit of all receive connectors of Exchange server with the below command?  Please guide me on this case.

Get-ReceiveConnector | Set-ReceiveConnector -MaxMessageSize 50MB

Assuming you are ok with every RC being configured with a 50 MB limit then yes that's all you need for the RCs.  Don't forget about Send Connectors.

Hi Jason,

Thansk for replying. I just want that my users can send and receive the emails upto 50 MB size. There is only one send connector for all mail-domains so I will increase the size for it.

I am not sure about the Receive Connectors that against which Receive Connector, I need to increase the size. Should I need to increase the size against all receive connectors?

If you just need to increase the size of emails you receive from the internet, then the only one you need to modify is the Default FrontEnd receive connector. If you have additional Receive Connectors for application and device SMTP relay, you may wish to also increase those as well.

Unless you can identify a legitimate agrument against it specific to your organization, you should be good using

Get-ReceiveConnector | Set-ReceiveConnector -MaxMessageSize 50MB

Repeat the same command for your Send Connectors.
