Improved performance when open for an extended period
I've been running Outlook on a MacBook Pro 2016 13" and I've noticed that when I have Outlook open for an extended period of time, days, it starts to be slow to respond when switching windows. For instance, clicking send on a new email will pause for a moment before going away. When the app is fresh, the response is immediate. I rarely shutdown my Mac, and I frequently sleep it by closing the lid. If I close Outlook and reopen it immediately, the responsiveness returns to what I would expect. It feels like something is caching and slowing the responsiveness when it's open for a long time.
