How do I synchronize LWS calendar and contacts on Android?

Procédure

This help explains how to sync your LWS calendars and contacts on an Android phone or tablet.
Calendars use the CalDAV protocol.
Contacts use the CardDAV protocol.
On Android, these two synchronizations can generally be configured from the same DAV-compatible application.

Before you begin

You must have:

• an active LWS email address;
• the password for that email address;

Retrieve the DAV settings from LWS Webmail

Log in to your Roundcube Webmail with the email address whose calendar you want to synchronize.

In the left-hand menu, click Settings (1).

Then click Device Config. (2).

Select the device Android™ (Google Pixel™, Samsung Galaxy®, etc.) (3) from the list provided.

Roundcube then displays the settings to use for your account. Find the DAV settings section.

You need to retrieve the following information:

• URL : main DAV address;
• Alternative URL : secondary DAV address, to use if the first one does not work;
• Port : generally 443;
• User : your full email address.

Install a CalDAV and CardDav compatible application on Android

Android does not always allow you to directly add a CalDAV and CardDAV calendar from the phone settings. In this case, you must install a CalDAV-compatible application.

You can use a maintained CalDAV/CardDAV synchronization application, for example DAVx⁵, or any other CalDAV-compatible Android application.

Once the application is installed, open it to add a new account.

Add your LWS calendar in the CalDAV application

In the synchronization application, choose to add an account by URL and username if this option is offered.

Then enter your account information:

• URL : paste the DAV URL retrieved from Roundcube;
• Username : enter your full email address;
• Password : enter the password for this email address.

Confirm the account addition.

The application then searches for the available calendars and address books.

Depending on your service, you may see:

• one or more calendars;
• one or more address books.

Enable the items you want to synchronize on Android.

Choose the items to synchronize

After adding the account, select the data you want to find on your Android device.

To synchronize your calendars, enable the calendars offered by the application. They will then be visible in your phone's Calendar application.

To synchronize your contacts, enable the address books offered by the application. They will then be visible in your phone's Contacts application.

You can enable only calendars, only contacts, or both according to your needs.

Display the calendar in the Android Calendar app

Then open your phone's Calendar / Agenda application.

Depending on the application used, you may need to display the list of available calendars and check the calendar corresponding to your LWS email address.

If the calendar does not appear immediately, start a manual synchronization from the CalDAV application or wait a few minutes.

Display contacts in Android

Open your phone's Contacts application.

Depending on the application used, you may need to open the contacts display settings and select the address book linked to your LWS email address.

If the contacts do not appear immediately, start a manual synchronization from the DAV application or wait a few minutes.

Check that everything works

To verify calendar synchronization, create a test event from your LWS Webmail calendar. Wait a few moments, then check that this event appears in the Calendar application on your Android device.

To verify contact synchronization, create a test contact from your LWS Webmail address book. Wait a few moments, then check that this contact appears in the Contacts application on your Android device.

If your application allows it, you can also do the reverse test: create an event or contact from Android, then check that it appears in LWS Webmail.

Common issues

The application refuses to add the account

Check that the DAV URL was copied from Settings > Device Config. in Roundcube.

Also make sure that the username matches your full email address.

If the main URL does not work, try the alternative URL shown in Roundcube.

The application indicates a password error

The requested password is the one for the LWS email address, not your LWS client area password.

If you are no longer sure of the email address password, change it from your email management interface, then try the setup again.

The calendars or contacts are synchronized, but I cannot see them

Check that the LWS calendars or address books are enabled in the Calendar or Contacts applications.

In some cases, the data is synchronized but hidden in the display. Open the settings of the application concerned and check the displayed calendars or accounts.

You can also force a manual synchronization from the DAV application.

I can see my emails, but not my calendars or contacts

Email setup, calendar setup, and contact setup are three different settings.

Even if your mailbox already works on Android, you must add calendars and contacts separately using the DAV settings.

The calendar works, but not the contacts

Check that the address book has been selected in the DAV application.
Some applications allow calendars and contacts to be enabled separately.

Contacts appear twice

Duplicates can come from several accounts displayed at the same time on Android, for example the phone's Google account and the LWS address book.

Check the address books displayed in the Contacts application and hide those you do not want to display. Do not delete contacts without checking in which address book they are stored.
