Same issue here. Some reminders work, others don't. I notice it, as previously mentioned, where individual occurrences are having their reminder set to "None" while the meeting series is set to a value. Also as mentioned, the occurrence is NOT broken from the series (no slash). Works fine on Android mobile app, but not PC desktop app. Causing major issues at work for me.
I am noticing the same manifestation. The meeting series is set a have reminder, but an individual occurrence has the reminder set to "none." The individual was never edited to be different from the series. So there is no reminder for the meeting.

Outlook Calendar Reminders Not Working

Last week I removed Microsoft 365 from my PC in my office using the https://support.microsoft.com/en-us/office/uninstall-office-from-a-pc-9dd49b83-264a-477a-8fcc-2fdf5dbf61d8 and installed a fresh copy. Once it was done, I checked for an update and it installed one. Since then, I have been getting all my reminders again.
so this didn't last long. the last couple days the problem is back. very frustrating to miss appointments etc because your calendar doesn't work. even more frustrating that no one from Microsoft has bothered to chime in here. not happy
