Hi, I've been looking into setting up Exchange GAL sync between 2 separate organizations (Exchange Forests). The requirements are for a 1 way sync (read GAL and update/delete/add contacts to GAL in org B as needed). I know FIM 2010 can do this, but I'm not sure about the requirements\setup. Reading the 'before you begin section' at http://technet.microsoft.com/en-us/library/ff512685(v=ws.10) mentions Sharepoint Services & website. Organization A in my scenario is large organization (around 6000 users) and organization B is small, I'd rather avoid installing Sharepoint 2010 if I can help it. Would I need to install and configure Sharepoint 2010 in both organizations for FIM 2010? For simplicity I'm looking at alternatives: http://www.wapshere.com/missmiis/galsync-v2 http://www.open-a-socket.com/index.php/2010/12/23/gal-sync-with-quest-quick-connect-express-for-active-directory/ ThanksIT Support/Everything

Hi, You only require the FIM Synchronization Service in order to achieve this. Therefore you do not need the FIM Service (Portal); therefore you do not need any Sharepoint components either. Regards, SK

Thanks, To install FIM sync between 2 organizations, I'm assuming I'd need the client and server component? Am I right in thinking I'd need the server in organization A (holds master GAL) and the client in organization B (holds the GAL to be modified)? Also, I take it terms of communications between the two organizations, the main things I would need are ports 5725 and 5726 for the client to server communication and the server portal being contactable via https?

Hi, Install one FIM Sync server in Org A. Setup 2 GALSYNC MAs, one MA to Org A and the other MA to Org B. The port you would need open is either LDAP or LDAP over SSL (depending on your security requirements). Please take a look at the following resource for all the information & walkthroughs: http://social.technet.microsoft.com/wiki/contents/articles/1726.global-address-list-synchronization-galsync-resources.aspx Hope this helps, Regards
