I have a user who is using Outlook 2011 for Mac, they are setup as a Moderator for a Distribution Group. They recieve the "approval requested" notification emails. But can not do anything because there is no approve or deny buttons showing up in the email.  They do get the option if they use the Outlook web app.

Is this not a feature in Outlook for Mac users ? Or is there a setting or something I am missing?

Thanks
