I created an InfoPath Client Event and configured it to send Email notifications. I deployed this workflow and everything worked fine till now.

When I try to re-deploy the same workflow again, without any change, then I am getting this error:

If un-check the radio button for sending notification event, then the deployment is successful, but the destination user is still getting an email Notifications regarding the task. For some reason, the system is unable to un-check this radio button.

I can not see notifications of this process under Workspace-Notification event designer. I am not sure if this is related to the above error I am getting.

I really appreciate any help in this regard.......

Thanks,
