Three Outlook Calendar steps change events: Create an event — Puts an event in a calendar, with a Teams meeting if you like; Update an event — Changes an event — only what you fill in; and Delete an event — Removes an event from its calendar.

Who can do this

Workspace Admins and Editors, on every plan.

Before you start

A Microsoft 365 connection allowed to Read and write calendars.

Steps

Create an event:

  1. Select +, then in Apps select Outlook Calendar, then Create an event.
  2. In Connection, choose your Microsoft 365 connection.
  3. Optional: in Calendar, choose one — Your calendars, and those shared with you that you can edit. Empty: your own calendar.
  4. In Title, type the event's title.
  5. In Starts, the date and time — 2026-10-05 10:00 — or a value from an earlier step.
  6. Under Lasts, choose from 15 minutes to 8 hours, or All day. It starts on 1 hour.
  7. In Time zone, the zone Starts is in — The workflow's time zone unless you choose another. It starts on yours.
  8. Optional: in Attendees, addresses — Each gets Outlook's invitation. Separate several with commas.
  9. Optional: switch on Add a Teams meeting.
  10. Optional: Location and Details.

Update an event:

  1. Select +, then Outlook Calendar, then Update an event.
  2. Choose the Connection.
  3. In Event, the event's id — An event's id — from Create an event, or List events.
  4. Fill in only what should change: Title, Starts (Empty keeps the time it has.), Lasts (Keep its length by default), Time zone, Attendees (Replaces who is invited. Empty keeps them.), Location, Details.

Delete an event:

  1. Select +, then Outlook Calendar, then Delete an event.
  2. Choose the Connection, and put the id in Event — When you organised it, the attendees get Outlook's cancellation.

If something goes wrong

What you see Why What to do
Starts "next Monday" is not a date and time — write it like 2026-10-05 10:00. Starts could not be read. Write it as a date and time.
Asia/Mumbai is not a time zone Bizomate knows. Choose one from the list. The time zone is unknown. Choose one from the list.
Nothing to change — fill in what the event should become. Update has nothing filled in. Fill in at least one thing to change.
Outlook Calendar refused: … Microsoft refused — the event or calendar is not there, or not editable. Read the reason; check the id and calendar.
Needs permission to read and write calendars The connection lacks the permission. Select Reconnect.
