Experts,

I'm using Exchange 2010 with Outlook 2010.

I use distribution lists with mail contacts to send to our membership.  I'm looking to clean up my Exchange mail contacts and I know that if they aren't attached to any DL's after I've created this year's lists, that they can be purged.  
I'm trying to create a list filtering on addresslistmembership, assuming if the value is zero, I'll get my results.  I'll then export it to csv, check it then run a purge based on an edited CSV.
So here's what I tried:
Get-contact | where {$.addresslistmembership –eq 0}
I get nothing with this...

However, if I reverse it:
Get-contact | where {$.addresslistmembership –ne 0}

I get a list of contacts that are attached to DL's.  

Not sure what I'm doing wrong or how best to approach this and I'm looking for suggestions.

Thanks!
