This is affecting all users of mine with 2013 on prem, I have admin rights others are sales person. If we make a task and instead of saving it we hit save and mark complete (or whatever the option is) it does it and completes it. However if
we make a task then later go in, hitting "Mark Complete" does nothing. Can press it 10 times nothing happens. If I click the Close Task and select a reason and hit Ok, again nothing happens. The only way to close one as complete
is I've had to make a workflow that when run changes the status to complete. That works and closes it. The event viewer shows no errors and I'm at a loss for why this might not work. I'm not sure if it ever has worked as we just started using
tasks and 2013. Any ideas on where I could check or why it might not work? Thanks!
