Hello Don,
No worries at all. I appreciate the assistance.
I had tried this previously after your advice to remove the second Select-Object condition, and it returns all other child properties of the -ExpandedProperty. It doesn't tell me the accounts that don't have an EUM entry in their list of emailaddresses.
Here is the query that I ran: Get-Recipient -ResultSize unlimited | select -ExpandProperty emailaddresses | where {$_.prefixstring -ne "EUM"}
Regards,
Brian
