During a project, I need to migrate about 100 Distribution Groups from personal contact folders to a Active Directory. I need to have them to be display under Global Address List and managed by assigned users. My Exchange Administrator is agains this move saying; "that it will too many DGs to manage". Unfortunatelly, the way is the only way I can offer to end users to provide access distribution groups they need to manage. Question: I am sound silly, but is there any limitation which would prevent to create such numebers of DS onto exisiting AD structure? Windows Server 2003 Domain, about 1800 contacts and 150 DG. Thank you all in advance. Bart Bart Kurowski IT Desktop Support Analyst, MCP, MCTS, MCITP, MCAS

Hey Bart, Active Directory can keep large number of objects and as for as 100 DG should not be any problem. Please refer to below link for Active Directory Maximum limits; http://technet.microsoft.com/es-es/library/active-directory-maximum-limits-scalability(WS.10).aspx http://www.agileit.com/blog/lists/posts/post.aspx?id=644

I do agree that it may be too much to mamage but this really depends on your IT resources and what the Exch admin means by "manage". Even so, they're not hard to manage, in particular that size, even 1 Exch admin can do this.Sukh

100 DGs are not too many to manage. if you are using Exchange 2010 DG management is very easy taks. you can let end users manage DG. you can set DGs in such a way that user can leave/join DGs themselves or with owners approval Dhruv
