Hi Maher, Thank you for the information. What is the limit in Exch 2007 RegardsSujit

Yes you can manage it through Active Directory User & Computers, Go to ADUC ->View->Advanced Features->Find Distribution list in domain and then Go to Security Tab->Add User and give him writes to add member and remove member or full rights -------- Best Regards, Muhammad Zahid

Hi, @Sujitdas: I haven't exactlly a perfect answer! but I think is in ther order of thousands of owners. see this article about active directory limits, really it's interesting: http://technet.microsoft.com/fr-fr/library/active-directory-maximum-limits-scalability(WS.10).aspx Best Regards Don't forget to mark it as answer if it helps

Hi, It is impossible to add more owners to a distribution group in Exchange 2007. When I try to use M.Zahid’s way to add more than one user and click OK, the error message occurs and shows ‘More than one object is selected. Only one object can be returned. Remove extra objects and press OK’. Instead, when I only specify a user, contact, or group as the manager for this distribution group, it works fine. Hope this helps.
