From 05/18 ~21:30 UTC until 05/19 ~10:00 UTC, Microsoft calendars were failing to sync due to an expired Microsoft OAuth Client credential. Due to the nature of the failure, alarms were not correctly setup which lead to the delayed resolution. The sync failure led to some events not having their auto-record rules applied if the event was created or edited during the outage window. The team has put in place mitigations to prevent this failure state in the future.
