Get All Users With Permissions For A Mailbox

Problem

You want to find all users and their permissions for a mailbox.

Solution

$mailbox = # put the mailbox you want to check
Get-EXOMailboxPermission -Identity $mailbox |
Where-Object {$_.User -ne "NT AUTHORITY\SELF"} |
Select-Object @{Name="DisplayName";Expression={(Get-Exomailbox -Id $_.User).DisplayName}},AccessRights,InheritanceType

Discussion

The default user, NT AUTHORITY\SELF, is excluded from the results. A calculated property is used to show the DisplayName of the user.
