Calendar Create userImpersonation functionality to replace EWS API feature
We have a pair of business workflows which have been for 10+ years been creating calendar items via the deprecated EWS API's. When moving to Exchange Online there is no like functionality.
Scenario 1) Corporate calendar for all employees - all-day calendar items that are free with no notifications
Scenario 2) faculty schedules are exported out of our ERP system and loaded via EWS API's to the faculty member calendars.
