> How to sync Davnode Calendar and Contacts on Windows using Thunderbird or Outlook.

# Syncing with Windows

This guide explains how to configure Davnode on Windows.

> **Note:** The native "Mail & Calendar" app and the "New Outlook for Windows" do not currently support generic CalDAV/CardDAV servers. We recommend using **Thunderbird** or **Outlook Classic** with a plugin.

## Server Settings

Keep these settings handy for configuration:

| Service                | Server             | Port  | Encryption |
| :--------------------- | :----------------- | :---- | :--------- |
| **CalDAV** (Calendar)  | `mail.davnode.com` | `443` | SSL/HTTPS  |
| **CardDAV** (Contacts) | `mail.davnode.com` | `443` | SSL/HTTPS  |

## Option 1: Mozilla Thunderbird (Recommended)

Thunderbird supports CalDAV and CardDAV natively without extra plugins.

### 1. Add Calendar (CalDAV)

1. Open Thunderbird and switch to the **Calendar** tab.
2. In the left sidebar, right-click and select **New Calendar...**
3. Select **On the Network** and click **Next**.
4. Enter the **User Name** (your Davnode email).
5. For **Location**, enter the server URL:
   `https://mail.davnode.com`
   *(Or the specific calendar URL if your setup requires a full path)*
6. Click **Find Calendars**.
7. Enter your Davnode password when prompted.
8. Select the calendars you wish to sync and click **Subscribe**.

### 2. Add Contacts (CardDAV)

1. Open the **Address Book** tab in Thunderbird.
2. Click the arrow next to **New Address Book** and select **Add CardDAV Address Book**.
3. Enter your **User Name** (Davnode email) and **Location**:
   `https://mail.davnode.com`
4. Click **Continue**.
5. Enter your password if prompted.
6. Thunderbird will detect your address books. Click **Continue** to finish.

## Option 2: Microsoft Outlook (Classic)

Outlook does not support CalDAV/CardDAV natively. You must install a plugin. We recommend the free open-source **Outlook CalDav Synchronizer**.

### 1. Install Plugin

1. Download and install [Outlook CalDav Synchronizer](https://caldavsynchronizer.org/).
2. Restart Outlook. You will see a new **CalDav Synchronizer** tab in the top ribbon.

<Note>
  We recommend to always use an **app password** for connecting calendars and
  contacts.
</Note>

### 2. Configure Calendar

1. Click **CalDav Synchronizer** > **Synchronization Profiles**.
2. Click the **+** (Plus) icon to add a new profile.
3. Select **Generic CalDAV/CardDAV** and click **OK**.
4. Configure the profile:
   * **Name:** Davnode Calendar
   * **Outlook Folder:** Select your Calendar folder.
   * **DAV URL:** `https://mail.davnode.com/`
   * **Username:** Your Davnode email.
   * **Password:** Your Davnode password.
5. Click **Test or discover settings**.
6. Select your calendar resource and click **OK**.

### 3. Configure Contacts

1. In the **Synchronization Profiles** window, click **+** again.
2. Select **Generic CalDAV/CardDAV**.
3. Configure the profile:
   * **Name:** Davnode Contacts
   * **Outlook Folder:** Select your Contacts folder.
   * **DAV URL:** `https://mail.davnode.com/`
   * **Username:** Your Davnode email.
   * **Password:** Your Davnode password.
4. Click **Test or discover settings**.
5. Select your address book resource and click **OK**.

## Troubleshooting

### "Calendar Not Found" in Thunderbird

If Thunderbird cannot auto-detect the calendar at the base URL:

* Try entering the full path to your specific calendar if you know it (e.g., `https://mail.davnode.com/calendars/user@davnode.com/default/`).

### Outlook Plugin Sync Issues

If Outlook is not updating:

1. Go to the **CalDav Synchronizer** tab.
2. Click **Synchronize Now** to force an update.
3. Check **Reports** to see if there are authentication errors (ensure your password hasn't changed).
