List Mailboxes in Exchange 2010 using Powershell

This will list user mailboxes – mailboxes that are not resource mailboxes (rooms, calendars, etc.).

Does not work cannot match on actual word “False” (or “True”):

get-mailbox -resultsize unlimited | where { $_.IsResource -eq ‘False’ } | select Alias, Name, IsResource, IsMailboxEnabled | ft -auto

Instead you must match on the results of the evaluation:

get-mailbox -resultsize unlimited | where { $_.IsResource -eq $False } | select Alias, Name, IsResource, IsMailboxEnabled, OrganizationalUnit | ft -auto

Get number of user mailboxes:

$c = get-mailbox -resultsize unlimited | where { $_.IsResource -eq $False } | select Identity
$c.count
