I am currious what methods there are the sharing of one organizations email addresses with another company? Scenario: Company A and B are on separate independent domains. Exchange 2007 is being used by both. Company A want's its Outlook users to be able to view Company B's user addresses. This would ideally happen without Company B's addresses being intermixed with Company A's GAL, but rather maybe a separate contact list or via multiple GALs. What methods are there to accomplish this?Are there any free tools out there that offer synchronization between two organizations?What are recommended pay tools that accomplish this? Ideally, we are looking for a simple, low maintenance solution. Of course free option would probably be ideal. Sugestions? thanks

I will look into ILM. Any other suggestions or 3rd party products would be helpful. thanks

I have looked into GALSync by netsec and Quest Softwares Collaboration product. I guess my question now becomes: Are there any free or less expensive options out there that are worth while?

Hi, ILM is recommended by Microsoft. For other third party products such as GALSync, we have no sufficient information. your understanding wouldbe appreciatd. Fiona Liao TechNet Community Support
