I am using "Send Notification" action to send email to a SharePoint group. I have checked the option "Send Individually Addressed Notifcations". . The users report that they have received the same email twice and I have seen the emails that they have sent.They show the same time exactly and inspite of me checking the option "Send Individually Addressed Notifications" I see all the people of the SharePoint group in the "To" list. . When I checked the workflow history I see that the workflow has run only once. Has anyone faced the same issue before , can somebody suggest why this is happening. I am clueless....
