I've a workflow attached to form library run with item created or updated. When item created, workflow starts and show status as InProgress but not execute any action. My first action is to send email but that itself not executed. This is happening for particular users and how to fix this issue?
How long did you wait? The default wait time for jobs to launch is 15 minutes (they are marked "In Progress" until the SharePoint Timer Service actually gets around to running the job). You can reduce this to 1 minute in Central Admin.
