Message size limits are an important mechanism to control mailbox sizes. One commonly asked question is about message size limits. There are basically three places where you can configure default message size limits on Exchange:
- Organization transport settings
PS > Get-Transportconfig | ft maxsendsize, maxreceivesize
- Send and receive connector settings
PS > Get-Receiveconnector | ft name, maxmessagesize PS > Get-Sendconnector | ft name, maxmessagesize
- User mailbox settings
PS > Get-Mailbox Username | ft Name, Maxsendsize, maxreceivesize
Examples
The example below shows how to increase the size of messages accepted by the transport service to 35MB:
PS > Set-TransportConfig -MaxReceiveSize 35MB
To set message size limits on a mailbox to 20MB:
PS > Set-Mailbox "Nicolas" -MaxSendSize 20MB -MaxReceiveSize 20MB
