Many Thanks Javier!, It worked as expected.
I added a condition in the event as follows in order to check whether other user has accepted that task or not.
If “last Accepted user” is empty. That means, if no user has accepted the task, then trigger the rule after 2 mins which will re-assign or route the task to another user.
I tested both scenarios. User 1 accepted the task; the rule never triggered. User 1 did not accept the task; Rule triggered, task was routed to User 2.
This is what exactly i wanted to implement for my case.
Thanks again for quick response.
