i get notification mail in fim 2010 whenever a request to add user in group is raised in fim portal...but how can a DL owner get mail in which he would be able to approve requests directly by pressing button in mail rather than entering into fim portal to approve request?

Hi, First of all you should have installed the Outlook Add-in on your local computer => Installation Guide More information on Distribution Groups and the Outlook Add-in can be found in the Getting Started section. Kind Regards, Stefan
