How to Determine Account Type?

Question

In my script I need to know whether an account is a Mail-User, Mail-Contact or licensed user account.

Presently I have to know this before-hand

Answer 1

The RecipientTypeDetails specifies the type of recipients returned.

You can select from the following values with Get-Recipient:

1. ArbitrationMailbox
2. ConferenceRoomMailbox
3. Contact
4. DiscoveryMailbox
5. DynamicDistributionGroup
6. EquipmentMailbox
7. ExternalManagedContact
8. ExternalManagedDistributionGroup
9. LegacyMailbox
10. LinkedMailbox
11. MailboxPlan
12. MailContact
13. MailForestContact
14. MailNonUniversalGroup
15. MailUniversalDistributionGroup
16. MailUniversalSecurityGroup
17. MailUser
18. PublicFolder
19. RoleGroup
20. RoomList
21. RoomMailbox
22. SharedMailbox
23. SystemAttendantMailbox
24. SystemMailbox
25. User
26. UserMailbox

What I am understanding from your case is that you need UserMailbox, User , MailUser , MailContact

I don't have an exchange setup right now. BUt you can set off with these value. It falls under Microsoft.Exchange.Data.Directory.Recipient.RecipientTypeDetails[]

Answer 2

I would probably look at RecipientTypeDetails to get the Mailbox type for the Mailbox/MailContact.

Maybe do the opposite if you have more MailContacts then Mailboxes in order to optimze it.

And I guess by "Licensed" you mean a UserMailbox? Since you do not mention Azure AD. In Azure AD you have IsLicensed with Get-MsolUser.

function GetAccountType($user)
{
    $Mailbox = Get-Mailbox -identity $user | select name, RecipientTypeDetails
    $type = ""
    if ($Mailbox.RecipientTypeDetails -eq "UserMailbox")
    {
        $type = "Licensed"
    }
    elseif ($Mailbox.RecipientTypeDetails -eq "SharedMailbox")
    {
        $type = "Shared"
    }
    else
    {
        $MailUser = Get-MailContact -identity $user | select name, RecipientTypeDetails
        if ($MailUser.RecipientTypeDetails -eq "MailContact")
        {
            $type = "Mail-Contact"
        }
        else
        {
            $type = "Something else"
        }
    }
    $type
}

$a = GetAccountType -user "userid"
$a | Out-Host
