Couldn't find a thread on this but please direct me if there is.
I tried setting up MfE for my corporate account. Didn't work (syncing stalled), perhaps because they've locked out devices the company doesn't provide.
In any case I still get alerts for recurring appointments even though the calendar is empty (every alert twice actually). I've tried wiping/deleting all calendars and of course removing the MfE account but it didn't help.
I'm assuming there's a file somewhere where this is stored but unfortunately I don't know enough Linux to find it so I can wipe it.
The strangeness continues. I renamed calendardb. Another much smaller was created (with no appointments as far as I could tell by viewing in Midnight Commander), and I still got an alert yesterday. Might not have rebooted the system after the renaming though. Guess I ought to try that.
