Connect Outlook Calendar
Connect a Microsoft account and bring its Outlook calendars into Harmonise.
Before you begin
- A supported personal, work, or school Microsoft account
Connect Outlook Calendar to see your Microsoft calendar events alongside your other plans in Harmonise.
If you have permission to edit an Outlook calendar, Harmonise can also sync supported event changes back to Microsoft.
Before you begin
You can connect a supported personal, work, or school Microsoft account.
Work or school accounts may require approval from your Microsoft 365 administrator.
Your Outlook connection shares the same connected-account allowance as Google, Apple, Yahoo, and CalDAV accounts.
On mobile
- Open Settings > Calendars.
- Under Calendar integrations, select Connect Outlook Calendar.
- Sign in with your Microsoft account.
- Review and approve the requested calendar access.
- Return to Harmonise and wait for your calendars to appear.
If you cancel the Microsoft sign-in process, no connection is created.
After connecting
Your connection may briefly show Pending while Harmonise verifies your account and finds your calendars.
Once connected, you can:
- Show or hide calendars
- Turn Sync on or off
- Choose an eligible default calendar
- Map connected calendars to calendars in Harmonise
See Choose calendars from a connected account for more information.
Editing Outlook Calendar events
What you can change depends on your access to each Outlook calendar.
- Read-only calendars can be viewed in Harmonise but cannot receive event changes.
- Editable calendars can receive supported event creates, edits, and deletions.
Recurring events may ask whether you want to change one occurrence or more of the series.
Tasks remain Harmonise Tasks and do not become Microsoft To Do tasks.
Names and colours
Connected calendar names and colours are controlled by Outlook.
Make changes in Outlook first, then select Refresh calendars in Harmonise.
Calendars created directly in Harmonise can be renamed and recoloured in Harmonise.
Refresh or sync your calendars
Use Refresh calendars when you add, remove, share, rename, or change access to an Outlook calendar.
Use Sync now if an existing calendar is connected but its events appear out of date.
Some changes may take a short while to appear.
Disconnect or reconnect
Select Disconnect to stop syncing that Microsoft account with Harmonise.
If the connection shows Error or Revoked, reconnect the same Microsoft account and review your calendar settings again.
If your organisation blocks the connection, ask your Microsoft 365 administrator whether Harmonise calendar access is allowed.
