# ActiveSync / EAS - Sync Email, Calendars and Contacts

### Sync your email, calendar, and contacts in real-time.

**ActiveSync** is the most powerful way to connect your mailbox to your mobile devices and desktop apps. Unlike standard email setups, ActiveSync provides a "push" connection that synchronizes your **email, calendar, contacts, and notes** instantly across all your devices. When you delete an email on your phone, it’s gone from your computer; when you add a meeting to your calendar, it appears everywhere.

<p class="callout info">**Note:** ActiveSync is a premium feature available for **Enhanced mailboxes**.  
</p>

<p class="callout success">**Pro Tip:** If your configured [Autodiscover](https://wikidev.emailarray.com/books/1-configure-a-new-e-mail-address-getting-started/page/dns-configuration#bkmrk-5.-autodiscover-reco) in your domain’s DNS settings, you can often skip the manual server entry. Simply enter your email and password, and the device will find the correct server settings automatically.</p>

#### Pre-requisites

Before starting, ensure you have the following details ready:

- **Your Full Email Address:** (e.g., john@mydomain.com).
- **Your Password:** The same password you use for webmail.
- You have added the [Autodiscover DNS record for your domain](https://wikidev.emailarray.com/books/1-configure-a-new-e-mail-address-getting-started/page/dns-configuration#bkmrk-5.-autodiscover-reco) to simplify the configuration. Otherwise, you can use the manual setup.

1. Open the **Settings** app on your smartphone or tablet.
2. Navigate to **Mail** or **Accounts** and select **Add Account**.
3. From the list of account types, select **Exchange**, **Microsoft Exchange**, or **ActiveSync**.

#### Step 2: Enter Account Details

Simply enter your email and password, and the device will find the correct server settings automatically. Click on **Sign In** or **Finish**.
