Add me to the list of Office-365 and Outlook 2016 users who'd like to see pinned emails highlighted/pinned to the top of the Inbox.

I'd like to add to the list of frustrated users. Rules used to work reliably, but no longer. Plus the option for sweep is now completely gone.
I suspect the number of users utilizing rules and sweeps was overwhelming the servers (since it runs on the server side, not client side).
I pay for my MSN email account, it should work.
