So in exchange management shell I run the following command:

Get-TransportConfig | ft MaxSendSize, MaxReceiveSize

and it was at 10mb in and out, So I increase the max send recieve by running this command:

Set-TransportConfig -MaxSendSize 100MB -MaxReceiveSize 100MB

Check the settings and even rebooted the server last night, to no avail anything over 10mb still get's bounced.

Any ideas would be me appreciated.

Hi BJN,

there is a limit for outgoing messages(sendconnector), incominig messages (receive connector) as well as an iternal message size (transport config) in Exchange.
Please see https://technet.microsoft.com/en-us/library/bb124345(v=exchg.150).aspx

If you cannot resolve it using that article please provide the bounce.

Thanks,
