I am have a user who wants to attach a file larger than 10MB in Microsoft Exchange 2010. I have changed every size limit except the following...

ExternalDsnMaxMessageAttachSize

InternalDsnMaxMessageAttachSize

I have tried running this cmdlet that someone posted as follows but I get an error:

Set-TransportServer ” SERVERNAME ” -ExternalDsnMaxMessageAttachSize xxMB
Set-TransportServer ” SERVERNAME ” -InternalDsnMaxMessageAttachSize xxMB

The error is as follows:

The position peremeter can not be found that accepts argument "ExternalDsnMaxMessageAttachSize"

I have attached an image of when I run the "get transportconfig" command.


 These are the two values I need to change...
I have read and did all the steps for the other send and recieve parameters from the following site which was recommended on another post. Everything else is setup properly I just cant seem to change the internal and external attachsize limit. IT still shows 10MB. Thank you in advance for any help! =)

Also I have rebooted the server after I changed my other settings as well.
