Filter Mailboxes on Property 'IsInactiveMailbox'

Question

I am trying to filter all ACTIVE mailboxes into a variable for the purpose of examining outlook rules for data exfiltration.  Currently, all mailboxes are pulled and even with robustcloudcommand I am waiting days for the script to complete.  I have tried:

Get-Mailbox -ResultSize unlimited -Filter ($_.IsInactiveMailbox -eq '$False')

Get-Mailbox -ResultSize unlimited  | where {$_.IsInactiveMailbox -eq '$False'}

Using 'where', I get zero results in the data set.

Using 'filter', I get 'Cannot bind parameter 'Filter' to the target. Exception setting "Filter": ""False" is not a recognized filterable property. Valid property names are:'

Then it lists 'isinactivemailbox' as a filterable property.  I found a post to sort mailboxes by last login but that result doesn't account for things like staff tha tis on leave of absence. 

How can I filter and return my active mailboxes only?  Thank you for any help!  :)
