For example, to set the limit to 50 MB: powershell Set-TransportConfig -MaxSendSize 50MB -MaxReceiveSize 50MB Note that you should set the limit about 33% higher than the actual desired attachment size to account for Base64 encoding. So for a 50 MB attachment limit, you may want to set it to around 67 MB. Restart Exchange services: For the changes to take effect immediately, restart the Exchange services using: powershell Get-Service *Exchange* | Where {$_.D...
