Step-by-step Starting with Exchange 2010 SP1 multi-tenant: Manage your organizations


This tutorial is part of 4 parts tutorial on Exchange 2010 multi-tenancy support
Part 1: Installation of Exchange 2010 SP1 in hosting mode
Part 2: Creating and deleting Organizations in Exchange 2010 SP1 hosting mode
Part 3: Managing Organization in Exchange 2010 SP1 hosting mode
Part 4: Sending and receiving emails in Exchange 2010 SP1 hosting mode

In part 1 of this tutorial we have seen how to install exchange 2010 SP1 in hosting mode and in part 2 we learned to Create and Delete organizations. I will show you today in this tutorial the basic management of an organization like creating/deleting mailboxes.

Managing mailboxes as a hosting company

Creating mailboxes

We need to make the difference here between you, as a hosting company, creating users in a specific organization and the Organization Administrator creating users for its own organization.

To create, as a hosting company, users for a specific organization you will need to use the powershell command new-mailbox that, also, got new attribute -Organization.
Assuming I want to create a new mailbox for myself in the Organization “TestOrg” the command will be

New-Mailbox "Antoine Khater" -UserPrincipalName [email protected] -Organization TestOrg

06

As you can see the mailbox was created with the quotas define in the service plan of the TestOrg organization and with an email address of [email protected], and you can guess it will be located in the TestOrg organizational unit in Active Directory.
07

Deleting mailboxes

Well this is a really funny one and I think it is a bug actually. The remove-mailbox cmdlet didn’t get the -organization parameter which make it impossible to delete a mailbox unless you use the combination of get-mailbox and remove-mailbox as follows

get-mailbox [email protected] -Organization TestOrg | remove-mailbox

Managing Organization as Organization Admin

Well I know that most hosting companies provide their customers with panels to do the management however exchange 2010 provides a decent management interface which is nothing but the Outlook Web App ECP.

Remember that administrator password we have used when we first created our TestOrg in part 1 of this tutorial? Well it is now time to use it …

From the web browser reach https://casserver/ecp and logon with the organization username/password.
(one thing I’ve noticed is that now the OWA authentication page asks by default for the email address instead of Domain\Username)
11

After logging on you have the option to manage your organization
12

And there you will presented with the options of Creating new mailboxes/managing Mailboxes/reseting password and even creating SMTP rules and tracking emails

A look at address lists

I would like to add that, even if address list segregation is not supported yet on Exchange 2010 SP1, when installed in hosting (or multi-tenancy) mode each user will only see their Global Address Lists accounts that belongs to the same organization. So a user in the TestOrg organization will not see users in any other organization and vice-versa.

  6. Faded Jeans says:

    I did pretty well until I tried to surf to the /ecp/ page; I can't see anything.  I also don't see the IIS Manager, so I'm not sure what to do to troubleshoot this.  Where should I begin?

    Thanks a lot for the tutorial.  It's been a huge help.

  7. Faded Jeans says:

    I added the IIS7 Manager; I see all of the virtual directories that I expect to see.  i still can't view /owa/ or /ecp/.  I don't have an SSL cert assigned to this, but I added it to the tursted sites.  Is there anything else that I have to configure to see ECP/OWA/etc?

  8. TT says:

    I am able to manage and view mailboxes via the web interface and able to set up an android, but for some reason I cannot figure out how to set up an Outlook client from a remote location.
    Any information on how to configure the Outlook clinet for a hosted exchange box in this model?
