Sync Notion to Outlook Calendar in Minutes

The Missing Integration

If you use Notion for project management but your company runs on Microsoft 365, you've probably run into this wall: there's no native way to see your Notion dates in Outlook. Notion Calendar, the standalone app Notion launched to bridge this gap, supports Google Calendar and iCloud. But as of early 2026, Outlook support is still nowhere to be found.

That leaves a lot of people stuck. Microsoft 365 dominates the enterprise world, and Outlook is the default calendar for millions of teams. If you're one of them, you've been left out.

Why This Actually Matters

It sounds like a small inconvenience until you miss a deadline because it lived in Notion and not in the calendar you actually check every morning. When your project timelines are in Notion but your meetings and reminders are in Outlook, you end up context-switching between two systems constantly.

The real cost isn't the switching itself. It's the things that fall through the cracks when you forget to check one of them. A sprint deadline, a content publish date, a client deliverable. If it's not on your calendar, it doesn't feel real.

iCal Feeds: The Protocol That Solves This

There's a technology that's been quietly solving calendar interoperability for over two decades: the iCal feed. It's an open standard (technically called iCalendar, or RFC 5545 if you want to impress someone at a party) that lets any calendar application subscribe to a URL and pull in events automatically.

Outlook has excellent support for iCal feeds. You subscribe once, and events appear in a dedicated calendar alongside your existing schedule. They update on their own. No plugins, no extensions, no IT department approval needed.

The trick is getting your Notion data into an iCal feed format. That's where Notion to Calendar comes in.

Setting Up Notion to Calendar

The setup takes about three minutes. Here's how it works.

Head to notiontocalendar.com and connect your Notion account. You'll authorize the app to read your Notion databases through Notion's official integration system. Your data stays yours; the app just reads the date properties it needs to generate calendar events.

Once connected, choose the Notion database you want to sync. This could be a project tracker, a content calendar, an editorial pipeline, a CRM with follow-up dates, anything with a date property. Pick which date field should drive the calendar events, and you'll get a unique iCal feed URL.

Copy that URL. You'll need it for the next step.

Adding the Feed to Outlook Desktop

Open Outlook on your desktop. Go to File, then Account Settings, then click on Account Settings again in the dropdown. Select the Internet Calendars tab.

Click New, paste your iCal feed URL, and click Add. Outlook will ask you to name the calendar and set a few options. Give it something recognizable like "Notion Projects" or "Content Calendar." Click OK, and you're done.

Your Notion events will appear in Outlook's calendar view within a few moments. They'll show up in a separate calendar layer that you can toggle on or off, just like any other calendar in Outlook.

Adding the Feed to Outlook on the Web

If you use Outlook through the browser, the process is just as straightforward. Open Outlook at outlook.office.com and go to your calendar view. In the left sidebar, find Add calendar, then choose Subscribe from web.

Paste your iCal feed URL into the field, give it a name, pick a color if you like, and hit Import. The events will populate within seconds.

This also works in the new Outlook for Windows app, which uses the same interface as the web version. Same steps, same result.

What You'll See

Your Notion database entries show up as calendar events in Outlook with the title and dates pulled directly from your database. You get the full benefit of Outlook's interface: native reminders, color coding, overlay views with your other calendars, and the ability to see everything in daily, weekly, or monthly layouts.

The events refresh automatically. Outlook periodically checks the iCal feed for changes, so when you update a date in Notion, it flows through to your calendar without you lifting a finger.

Premium users of Notion to Calendar get a server-side refresh as fast as every five minutes, which means your Outlook view stays remarkably current. On the free plan, refresh intervals are longer but still fully automatic.

Works for Your Whole Team

Here's where it gets genuinely useful for teams. That iCal feed URL you generated? You can share it with anyone. Your colleagues subscribe to the same URL in their own Outlook, and everyone sees the same Notion data on their calendars.

The best part is that they don't even need a Notion account. The project manager updates deadlines in Notion, and the developer who lives in Outlook sees those changes reflected automatically. The marketing team tracks their content calendar in Notion, and the social media person who never opens Notion sees every publish date in their Outlook.

It removes the "but I didn't see it in Notion" problem entirely.

Being Honest About the Limitations

This is a one-way sync. Data flows from Notion to Outlook, not the other direction. If you drag an event to a new date in Outlook, that change won't make it back to Notion. Your Notion database remains the source of truth, and Outlook is the read-only view.

For most workflows, this is actually the right model. You want one place where dates are managed (Notion, where the context and details live) and another place where they're visible (Outlook, where your schedule lives). Trying to sync both directions usually creates conflicts and confusion.

The other thing to know is that Outlook controls how often it refreshes subscribed calendars. On the desktop app, this can range anywhere from one to twenty-four hours depending on your version and settings. Outlook on the web tends to refresh more frequently. If you need tighter sync intervals, the premium plan ensures the feed itself is updated every five minutes, so Outlook always has fresh data to pull whenever it does check.

Stop Checking Two Places

The gap between Notion and Outlook has been a pain point for a long time, and it doesn't look like a native integration is coming soon. But you don't need to wait for one. iCal feeds are a proven, reliable standard, and Outlook handles them beautifully.

Set it up once, and your Notion dates just show up where you already look every day. That's one less tab to check, one less thing to remember, and a lot fewer deadlines slipping through the cracks.
