# Set Up the Calendar Import Address

> Get your site's unique invitation email address to automatically create pre-registrations from Outlook, Google Calendar or Teams. Your staff keep their habits — Anghello takes care of the rest.

**Audience:** Administrators, Managers
**Application:** Admin (app.anghello.co)
**Estimated time:** 5 minutes

---

### Before you start

* Preregistration must be enabled on the site.
* You must be an **Administrator** or **Manager** to retrieve the invitation address.

---

### Steps

### 1. Get the site's invitation address

Go to `Settings` > `Sites` > Your site > `Settings & Features` > `Preregistration`. At the bottom of the page, find the `Site pre-registration email` field and click the copy icon.

The address looks like `my-site-xyz@invit.anghello.co`. It is **unique to each site**.

### 2. Share the address with your hosts

Share this address with the people who pre-register visits (hosts, managers, HR team, front desk…). They can add it as a recipient of their Outlook, Google Calendar or Teams events.

### 3. Test that everything works

See [How do I check that my setup works?](#) for a 2-minute test.

### The limits to know

| Limit | Value | Why? |
| ---- |
| **Visitors per invitation** | 10 maximum | To avoid accidentally importing mailing lists or internal team meetings. |
| **Time window** | Between today and 1 year in the future | To avoid mistakenly importing recurring events with an unlimited horizon. |
| **Authorized sender** | The event organizer must be an **Anghello user of the site** | Security: this prevents a third party from creating visits on your behalf. |

---

### Good to know

💡 **Tip:** The invitation address is **unique and unguessable** for each site. You can safely share it with your team — it can only be used by Anghello users of the site.

💡 **Tip:** Would you like a more readable address (for example `my-company@invit.anghello.com`)? [Write to us](mailto:support@anghello.co) — we can customize it.

### Troubleshooting

| Problem | Solution |
| ---- |
| I can't see the **Site pre-registration email** field | Check that preregistration is enabled on the site, and that you are an Administrator or Manager. |
| An invitation sent to this address didn't create a visit | See [My visitor didn't receive the pre-registration email](https://help.anghello.com/en/article/frequently-asked-questions-and-troubleshooting-polfte/). |
