I have one scenario that I need some help with. Hope you can give me some tips. One exchange server that is hosting two domains (a.com & b.com). Today, users at a.com and b.com can see each other address books. They don't wan't to see each other's address book. It is also possible that they will buy another company, that will get on the same floor and use the same computer system. Then we have problem with a, b and c.com. So, my question to the gurus out there is: How can I config the exchange only to let users a,b,c,d, see addressbook for the domain a.com, and users e,f,g only see the address book for the domain b.com?

Which version of exchange are you using??Follow this on exchange 2007 , this will guide you for multiple GAL hosting.http://www.msexchange.org/articles_tutorials/exchange-server-2007/migration-deployment/shared-hosting-exchange-2007-part1.htmlhttp://www.msexchange.org/articles_tutorials/exchange-server-2007/migration-deployment/shared-hosting-exchange-2007-part2.htmlhttp://www.msexchange.org/articles_tutorials/exchange-server-2007/migration-deployment/shared-hosting-exchange-2007-part3.htmlAlso you need to buy some kind of control panel (HMC, dotnetpanel etc) to get the full functionality of Segregating GALs, OAB etc from each other.Raj
