I've been noticing an issue for a while now, it seems to specifically impact the "New Outlook". I have Outlook pinned to my DF taskbar on my secondary monitor. If I click the pinned icon to launch Outlook, it spawns a second app icon instead of just marking the pinned icon as active. It happens every day, but as I said, it seems to specifically be "New Outlook".

Thanks for the update, at first glance looks to be working! I'll keep an eye on it and let you know if I see any further issues.

Unfortunately it looks like this came back. I'm currently on 12.1 beta 4.

Sorry for the delayed response, I was trying to test this before responding. Yes, even after unpinning and re-pinning I'm still seeing this pop up on occasion. It's not all the time (never was) but it is still happening.
