We have several Dynamic DL's that have a membership rule based on a particular account attribute being blank. I have no problem creating this through powershell.
My question is if a blank attribute rule can be created through the EAC? If you create a membership rule for "CustomAttribute2" and set it to $null in the EAC it doesn't work. It also will not allow you to just leave it blank.
Is there any way to create a blank rule condition not through powershell?
