Canceled meetings remain in the calendar with Canceled: title
So I have a lot of canceled meetings remaining in my calendar, with notifications and everything. Canceled: is prepended to the title, otherwise there's nothing changed. I think this mainly happens when a single occurrence in a series is canceled? Server is Office365 (over http proxy).

If you check the cancellation email in the official Outlook client, it shows a Remove from calendar button. This doesn't appear in Evolution, only a "Open calendar" button.
