Microsoft Outlook

CalKeep connects to any Microsoft account — personal Outlook.com, Microsoft 365 work/school, or Exchange Online — via OAuth and syncs your calendars two-way.

Connect​

  1. Go to Settings → Connected Accounts.
  2. Click Connect Outlook.
  3. Sign in with the Microsoft account.
  4. Grant the requested permissions (Calendars.ReadWrite, Contacts.Read).
  5. CalKeep imports your calendars and starts a two-way sync.

If your tenant requires admin consent, your IT admin needs to approve the CalKeep app once for the whole organization. After that, individual users can connect without a separate consent prompt.

What's synced​

  • All calendars on the account, including shared calendars and group calendars you have access to.
  • Events with full metadata: title, body, location, attendees, recurrence rules, Teams conferencing links.
  • Contacts (if you grant Contacts scope).

Disconnect​

Settings → Connected Accounts → [your account] → Disconnect. This revokes the OAuth grant on Microsoft's side. Events that already synced into CalKeep stay until you delete them.

Troubleshooting​

  • "Need admin approval" error on first connect: your tenant has admin-consent-required enabled. Forward the consent URL to your IT admin, or have them approve the CalKeep app from the Entra admin center → Enterprise applications.
  • Sync stopped after a password change: reconnect the account. Microsoft invalidates tokens on certain account events.
  • Teams meeting links not appearing: Teams links generate at event-creation time. If you create an event in CalKeep that's mirrored to Outlook, the Teams link is added by Microsoft after CalKeep posts the event.
