Well it does run continuously in the background. Just set is an unmonitored so you don't get the notification.I've used it for years and never had an issue until about 3 weeks ago. The device maintenance on my S8+ claimed it was using too much battery. I bought a Note 8 2 weeks ago and it did the same thing.
It went back up to .12 so I put it to sleep. The email I receive on that account isn't critical so I check it when I think about it.@jiinal how's Outlook doing now...?
