You can say that again. I have a recurring event in Outlook that has a reminder set. If I snooze that reminder, no matter the duration, it will never reappear.

This has been a core feature of Outlook for so long that it might as well be considered day-1 functionality. Why it breaks like this in 2026? Who knows...

I have to use Outlook and Teams for work, and both have had a notification symbol on with "1" unread items for most of the past year, even though clearly everything has been looked at.
