Hi,We are designing the DL structure dept. wise. I need to create one group, in which, users will be from our sister company. we do not have any relation in terms of AD or Exchange Org. They are completely seperate. We are using Ex2007 sp1.Can you tell me, how can i create DL having users email ids, from different domain.thanks,raj

Hi Rajiv,Since there isn't any relation between AD & Exchange, you need to create contacts manuallyin your AD/Exchange environment for the users of another compay (you may set "hide from GAL" option if you don't want to show in GAL), create aStatic/Dynamic Distribution Group depending on how you want to manage and add contacts to this Static/Dynamic DG.

You are the man. thx...Can you plz provide some more info/ link on ILM 2007 Feature Pack 1 ?thanks,raj

Hey Raj, I missed to ask your Exchange version, ILM 2007 FP1 can be used if you are using Exchange 2007 SP1. Otherwise you need to use MIIS 2003. Please find below link to deploy Exchange 2007 in cross-forest topology and to sync two GAL of different forests.Basically ILM & MIIS create contacts for all users of differnet GAL in other forest.

Since ILM is considered quite expensive (in terms of licensing cost) for many enterprises, I thought I would jump in and mention that you also can use IIFP (which is free!) with Exchange 2007. You just need to run a simple post task after objectsare synchronized to the target forest (sinceExchange 2007doesn't include RUS like previous versions of Exchange Server).

Kewl, thanks for the advice Henrik. My knowledge is poor on licensing & cost involved... :)Amit Tank || MVP - Exchange || MCITP - Exchange 2007 || http://ExchangeShare.WordPress.com
