Per-user settings should only be used as exceptions to org settings – they’re not set by default. Use this command to get a list of all mailboxes with MaxSendSize or MaxReceiveSize set to a non-default value:
Get-Mailbox -Filter {MaxSendSize -ne $null -OR MaxReceiveSize -ne $null} | ft Name,MaxSendSize,MaxReceiveSize
Get-TransportConfig | ft MaxSendSize, MaxReceiveSize Set-TransportConfig -MaxSendSize 50MB -MaxReceiveSize 100MB
Get-SendConnector | ft name, MaxMessageSize Set-SendConnector <Connector Name> –MaxMessageSize 50MB
Get-ReceiveConnector | ft name, MaxMessageSize Set-ReceiveConnector <Connector Name> –MaxMessageSize 50MB
Get-mailbox | ft Name, MaxSendSize, MaxReceiveSize Set-Mailbox "User Name" –MaxSendSize 50MB –MaxReceiveSize 50MB
