Nov 2–8: Stuck copies clear, shared Outlook calendars return

New and improved

If one calendar in a sync cannot be reached for 24 hours, the sync page shows which calendar and why. You can reconnect it or remove it. The other calendars keep syncing, and you get one email about it.
New guides: what to do now that Microsoft has retired calendar sync between Teams and Google Workspace, and an admin guide to Team calendar sync.
New guides: syncing an iCloud calendar into Outlook. The Team page has a new section for IT and procurement, and a new security page says what SYNCDATE does and does not do.

Shared and family Outlook calendars work again as sources and targets. Microsoft decides access. If Microsoft refuses, the sync shows access denied.
Events a sync had stopped copying are checked and copied again. Old "On hold" and "waiting" labels clear, including on large calendars.
Repeating events that were split, moved or shortened at the source copy correctly, with no old occurrences left behind. Edits to single occurrences sync again.
Events skipped by a stricter filter are copied once you widen the filter.
Recurring events that Outlook cannot store as a series copy as single events instead of stalling.
Events and recurring series deleted in an iCloud or other CalDAV calendar are removed from the copy.
Repeating events in Alberta and the Northwest Territories copy at the right time after the November clock change.
iCal feeds with custom time-zone names, very old dates or unusual start and end times now copy.
A calendar feed that refuses access shows "reconnect" instead of "waiting".
Connecting iCloud Calendar from mainland China no longer fails with a "crosses origin" error.
Calendars that had stopped receiving updates after a delayed change sync again.
A deleted past event no longer stays on the target calendar.
