Microsoft Outlook 2010 is not natively designed to be synchronized with CalDAV calendars or CardDav contacts, however with the help of a free plug-in that you can download and install, you can add these features. However, it requires some adaptations described here to work properly with your hosting with us.

The descriptions below are based on a Microsoft Windows 10 operating system. If you have another version, some operations may be slightly different, especially in terms of the location of buttons or texts displayed by the system interface.

Attention: what is described here is valid for all standard shared hosting accounts (MAIL, PERSO, EXPERT, ULTRA) but does not concern AlpMail type hosting.

You will find here how to proceed, in three steps:

  1. Download and install the CalDavSynchronizer
  2. plug-in;
  3. Configuration of the plug-in so that it can connect without errors to your accounts hosted with us;
  4. Configuration of the plug-in to add a shared account (CalDAV or CardDav);

Step 1: Download and install the plug-in

  • Close Microsoft Outlook 2010 completely: quit the application;
  • Download the "CalDavSynchronizer" plug-in at the following address: https: // "Download
  • " section, then select the latest version ("Latest release" in English). Download the associated .zip file;
  • Unzip the downloaded .zip file, if it is not done automatically by your system;
  • Double-click on the freshly extracted "setup.exe

" file and follow the installation instructions.

If you start Microsoft Outlook 2010 after this installation, you will see a new tab in the interface, at the very end: "CalDav Sycnchronizer".
At this point do not try to create a synchronization profile yet: it will not work properly until you have completed all the steps described below.

Step 2: Plug-in configuration

This plug-in as it stands is incompatible with our servers: it will indeed display synchronization errors and you will not get the expected result. Fortunately, it is relatively easy to get around this problem: you just have to modify one of your own configuration files to activate an option making it compatible. Here is how to do it:
