Outlook Calendar fields that sync to Notion

All 15 Outlook Calendar fields that sync to Notion with 2sync: property types, sync directions, and how to use categories, attendees, and meeting links

2sync syncs 15 Outlook Calendar fields to Notion, covering event subject, dates, location, attendees, categories, and meeting links. Most fields support two-way sync, letting you edit in either app. Read-only fields like organizer, recurring status, and calendar name sync from Outlook to Notion only. You control each field's direction in field mapping.

You can set each field to two-way, one-way to Notion, or one-way to Outlook. Adjust this per field in your automation's field mapping settings.

Subject

The Subject field maps to Notion's Title property, the main name of each database page. Changes to the event name in either app update the other automatically. For example, renaming "Sync Call" to "Weekly Sync Call" in Notion updates it in Outlook on the next sync cycle.

Description

The Description field maps to Rich Text. Basic formatting from Outlook (bold, italic, links, lists) is preserved during sync. Some Notion-specific elements like toggles, databases, and embeds cannot be represented in Outlook and will be lost if synced back. A meeting agenda pasted in Outlook with bullet points appears formatted in Notion, but Notion toggles added to the page won't survive a round-trip.

Changing a field's sync direction after initial setup does not retroactively update existing items. Only new changes follow the updated direction.

Dates

Start Date and End Date both map to Notion's Date property and sync in both directions.

For timed events, both date and time sync. For all-day events, only the date syncs without a time component. When a Notion page has a start date but no end date, 2sync uses the Default Duration from your advanced sync settings to calculate the end time.

Timezone conversion is automatic. Events display in your local timezone regardless of where they were created. A colleague in London creates a 3pm GMT meeting and it appears as 10am EST in your Notion database if that's your timezone.

Location

The Location field syncs as Rich Text in both directions. Type an address or place name in either app and it appears in the other. Outlook's room finder and room suggestions are not available in Notion; the location syncs as plain text only. Use it to build a Notion view filtered by location to see all in-office meetings.

Attendees

You can sync attendees in two ways. The Attendees (Text) field stores a comma-separated list of email addresses as plain text. The Attendees (Contacts) field links to your Outlook Contacts database using Notion relations.

Both can be active at the same time. The relation field is useful for building a CRM in Notion where calendar events link directly to contact pages, building a timeline of every interaction with a client.

Organizer

The Organizer field shows the email address of the person who created the event. This field is read-only because Outlook controls this value. When syncing shared calendars, use Organizer to identify who scheduled each meeting. Filter your Notion database to see only meetings created by a specific person.

Categories

Outlook Calendar uses categories instead of colors. Categories sync as a Multi-select property in Notion (see Notion property types), letting you assign multiple categories per event. Create categories in Outlook and they appear as select options in Notion automatically.

Categories sync in both directions. Adding a category in Notion applies it to the Outlook event on the next sync cycle. Tag events as "Client Meeting", "Internal", and "Travel" in Outlook. All three appear as Multi-select options in Notion, where you can filter views by category.

Is recurring

The Is Recurring field syncs as a Checkbox. Any event belonging to a recurring series has this box checked. Use it to build filtered views. Show only repeating meetings to review your weekly commitments, or exclude them to focus on one-off events.

For details on how recurring event instances sync, see recurring events.

Recurrence type

The Recurrence Type field classifies events into four categories: Single, Occurrence, Exception, and Series Master. Single events appear once. Occurrence is one instance of a recurring series. Exception is a modified instance. Series Master represents the recurring pattern itself. This field is unique to Outlook, since Google Calendar only has the simpler Is Recurring checkbox.

Use this field to filter recurring events in Notion views. Filter to "Exception" types to find meetings that were rescheduled from their usual time.

Some fields become immutable after event creation in Outlook. If a field stops syncing updates, check whether the event was created as part of a recurring series. Certain properties can only be changed on the series master, not individual occurrences.

Visibility and free/busy

The Visibility field supports three values: Public, Private, and Default. The Free/Busy field shows whether you appear as Busy or Free during the event. Both sync in two directions.

These fields are useful for filtering events by availability status or controlling which events appear in shared views. Exclude private events from a shared team database using filters, or filter to only Busy events so informational "Free" holds don't clutter your task list.

Microsoft Teams meeting links sync automatically when a Teams meeting is created. Third-party links (Zoom, Webex) also sync if present in the event. Click the synced Teams link directly from Notion to join a meeting without opening Outlook first.

Meeting Link is read-only in Notion. Add or modify meeting links directly in Outlook.

Calendar name

The Calendar Name field identifies which Outlook calendar an event belongs to. This is especially useful when you sync multiple calendars into a single Notion database.

You can map Calendar Name to three property types:

  • Select (recommended): Creates a dropdown with each calendar as an option
  • Rich Text: Stores the calendar name as plain text
  • Relation: Links to a separate database of calendars

Calendar Name is read-only, so to move an event between calendars, edit it directly in Outlook. Use it as a Select property to group and filter events by source calendar in Notion.

FAQ

What is the difference between categories and colors?

Outlook uses named categories (like 'Work', 'Personal') instead of fixed colors. Categories are more flexible than Google Calendar colors because you can create custom names and assign multiple categories per event.

Why do some fields stop updating after creation?

Outlook marks certain fields as immutable on recurring event instances. If an event is part of a series, some properties can only be changed on the series master, not individual occurrences.

Can I sync from multiple Outlook accounts?

Yes. Connect multiple Microsoft accounts and select calendars from each. All events sync to the same Notion database with the Calendar Name field identifying their source.

How does Recurrence Type differ from Is Recurring?

Is Recurring is a simple checkbox indicating whether an event repeats. Recurrence Type provides more detail: Single, Occurrence (instance of series), Exception (modified instance), or Series Master (the pattern definition).

Can I add custom fields to the sync?

No. You can only sync the 15 fields listed above. Custom Outlook fields are not supported. However, you can add Notion-only properties to your database for additional tracking.

Does Outlook Calendar have an Event Type field like Google Calendar?

No. Outlook doesn't classify events by type the way Google Calendar does (Default, Out of Office, Focus Time, etc.). Use categories or Recurrence Type for similar filtering in your Notion database.
