How to Connect Your Outlook or Microsoft Calendar to nocal

Connect Microsoft 365 or Outlook.com to nocal using secure OAuth. Learn what access nocal needs, what syncs, and why work or school accounts may require admin consent.

nocal works with both Microsoft 365 (work or school) and Outlook.com (personal) accounts, bringing your Outlook calendar into the same notebook-style timeline as the rest of your schedule. Connecting uses Microsoft's secure OAuth sign-in, so you authorize nocal without sharing your password.

Before you start

Install nocal and sign in first if you haven't — see install nocal on all your devices. Have your Outlook or Microsoft 365 credentials ready.

Connect your account

  1. Open nocal and go to Settings → Accounts (or Add account on first launch).
  2. Choose Microsoft as the provider.
  3. nocal opens Microsoft's sign-in page in a secure window. Sign in with your Microsoft 365 or Outlook.com account.
  4. Review the permissions nocal requests and select Accept.
  5. nocal returns to your timeline and starts its first sync.

Microsoft 365 accounts managed by an organization sometimes restrict which apps users can authorize. If your tenant requires it, you may see a message that an administrator must approve nocal before you can finish connecting.

If that happens:

  1. Note the consent prompt or any request-approval link Microsoft shows.
  2. Ask your IT administrator to approve nocal for your organization.
  3. Once approved, repeat the connect steps above.

Personal Outlook.com accounts don't require admin consent.

What access nocal requests

Account email/profileLabel the account so you can tell accounts apart

What syncs

  • Events from your Outlook calendars, including titles, times, locations, attendees, and descriptions.
  • Updates made in Outlook or in nocal, kept in sync both ways.
  • Notes you attach in nocal stay in nocal and stay linked to the event — see take notes on an event.

First-sync time

The first sync usually finishes within a few minutes. Accounts with long histories or many shared calendars may take longer. nocal keeps syncing in the background while you work.

Multiple accounts

You can connect several Microsoft accounts, or mix Microsoft and Google, and control visibility per calendar. See using multiple calendar accounts.

Note: nocal supports Google and Microsoft/Outlook calendars. It does not support Apple/iCloud calendars.

Troubleshooting

If events don't show up, work through the calendar not syncing checklist. For changing sharing or permissions on a calendar, do that in Outlook — see share an Outlook calendar.
