Several AVC users have reported problems with calendars in Outlook not working properly. Calendars would go missing, or actions within a calendar would not save, etc.
AVC ITS opened a ticket with Microsoft support, and it is a known issue being worked on by their engineers.
Our own AVC users also found part of the issue was the addition of calendars from outside of the AVC Microsoft 365 system.
