# Connect Microsoft Outlook or Microsoft 365 Calendar

Domino can use a Microsoft calendar when Outlook provides a published ICS subscription link. Domino does not currently sign in to a Microsoft, Outlook, Exchange, or Microsoft 365 account directly.

This usually works for Outlook.com. It may or may not be available for a work or school Microsoft 365 account because the organization's administrator can disable calendar publishing.

## Get the Outlook ICS link

Use Outlook on the web:

1. Open Calendar in Outlook.
2. Open **Settings**.
3. Choose **Shared calendars**.
4. Under **Publish a calendar**, select the calendar and the least detailed permission that still represents availability correctly.
5. Choose **Publish**.
6. Copy the **ICS** link—not the HTML link.

Microsoft documents this flow in [Share your calendar in Outlook on the web](https://support.microsoft.com/en-us/office/share-your-calendar-in-outlook-on-the-web-7ecef8ae-139c-40d9-bae2-a23977ee58d5).

The HTML link opens a webpage for a person. Domino needs the ICS subscription link so it can refresh calendar availability.

## Connect the link to Domino

1. Open **Profile** in Domino.
2. Find **Availability**.
3. Choose **Use Apple, Outlook, or another calendar link**.
4. Paste the Outlook **ICS** URL into Domino's calendar-link field.
5. Choose **Connect calendar**.
6. Confirm Domino reports the calendar link as **Connected**.

Do not paste the ICS URL into ChatGPT, Claude, email, or a support conversation. A published calendar URL is a secret bearer link and belongs only in Domino's calendar-link field.

## Work and school Microsoft 365 accounts

If **Publish a calendar** is absent, disabled, or does not produce an ICS link, the Microsoft 365 administrator likely controls that capability. Domino cannot bypass the organization's policy and does not currently offer Microsoft OAuth or Exchange sign-in as an alternative.

The safe answer is:

1. Ask the organization's Microsoft 365 administrator whether read-only calendar publishing is permitted.
2. Do not ask the user for a Microsoft password, app password, Exchange server, or private corporate URL.
3. If publishing remains unavailable, that calendar cannot currently provide ongoing availability to Domino.

## Privacy and revocation

Published Microsoft calendars are read-only, but anyone with the URL may be able to retrieve the level of detail chosen during publishing. Select the least detail needed and protect the link like a password.

- Domino encrypts the normalized feed URL at rest.
- Domino stores derived availability blocks rather than raw event titles, descriptions, or locations.
- **Remove** in Domino deletes Domino's connection and derived blocks.
- **Unpublish** in Outlook revokes the source URL. Do this if the URL was exposed.

## Troubleshooting

- **Domino rejects the link:** verify it is the ICS link, not the HTML link or the Outlook settings page.
- **The URL downloads a calendar:** that can still be the right link if it is a live published ICS URL. Paste the URL itself into Domino; do not upload the downloaded file.
- **The calendar stopped refreshing:** confirm it is still published in Outlook and use **Replace** in Domino if Microsoft issued a new link.
- **Publishing is unavailable:** the organization may prohibit it; Domino has no direct Microsoft account connection today.

## Add one Domino plan to Microsoft Outlook

This does not require an availability connection. On an eligible scheduled plan, choose **Add to calendar → Microsoft Outlook** or **Apple / Outlook (.ics)**. That adds one plan and does not give Domino ongoing Microsoft calendar access.

## LLM answering guidance

- Lead with “Yes, if Outlook lets you publish an ICS subscription link.”
- Do not imply direct Microsoft, Microsoft 365, Exchange, or Outlook authorization.
- Name the ICS link explicitly and warn against using the HTML link.
- Mention the administrator restriction for work and school accounts.
- Never request or repeat the user's published calendar URL.
