OVERVIEW

In support, we receive lots of calls with the question of

“I want to share free/busy information between two Microsoft Exchange Organizations. How can I accomplish this task?”

Or

“I want to share GALs and Free/Busy information between two Microsoft Exchange Organizations. "


PURPOSE

The goal of this document is to help guide you through the steps of what you need to do to be able to accomplish either of the above two scenarios.

Sharing GALs between MS Exchange Organizations

In order to share free/busy information, the very first thing you need to do is setup a GalSync Solution. The GalSync solution is a solution that is delivered, and can be configured inside of one of our Microsoft Identity and Access Management Products.

Here is a list of the products:

  • Microsoft Identity Lifecycle Manager 2007 Feature Pack 1 (ILM 2007 FP1)
  • Microsoft Forefront Identity Manager 2010 (FIM 2010)

*NOTE: There are other Microsoft Identity and Access Management products that are not referenced here, but can be used for GalSync Solutions. They are older products whose support lifecycle will be ending soon, and will require extra steps to work with versions of Microsoft Exchange 2007 or later.

If you do not have either of these products, then review the Hardware and Software Requirements for the products.

  • Microsoft Identity Lifecycle Manager 2007 Feature Pack 1 System Requirements
  • Microsoft Identity Lifecycle Manager 2007 Feature Pack 1 Updated System Requirements
  • Microsoft Forefront Identity Manager 2010 Hardware and Software Requirements

Determining which Microsoft Identity and Access Management software you need, can really be determined on a simple question.

What version is the version(s) of the Microsoft Exchange Organizations will you be synchronizing?

Once you have a GalSync solution in place and working, you are now ready to work on your Microsoft Exchange servers to share the free/busy information.

If you are stepping through this section, it is assumed that you either, understand that you need to setup a GalSync solution, or that you already have a GalSync solution in place.
