There is a mysterious stalemate occurs when you create a normal sharepoint Designer workflow with An action of sending a mail to a sharepoint group. The workflow runs fine when run under Administrator Account but shows status stopped when run under any other account like Contributor etc.
This occurs due to the fact that by default, the visibility of members of sharepoint group is granted only To the members of those group. Any other user outside that group cannot enumerate the members of the group And hence the workflow fails with the status as stopped. To resolve the issue, Go to Sharepoint Group settings And allow Everyone to see the members of group.
This issue engrossed my whole day due to the fact that, there is no error reported when this occurs.
