I am attempting to, due to a user request, change the ExternalDsnMaxMessageAttachSize attribute from the exchange management shell. When I run the following command:
set-transportconfig -ExternalDsnMaxMessageAttachSize 20 MB
It works perfectly.
When I run the same command as an admin in powershell, it won't run, and ultimately no changes are made.
I am a powershell novice to say the least, but am I missing something here?
Is there a way I could push these changes out?
