4. Click on Connect.

   Tip: By clicking on the eye symbol next to the text box you can display the password again.

If Outlook cannot connect to Posteo, it’s possible that your antivirus program is blocking the connection.

2. How to set up synchronisation of the calendar and address book

Unfortunately, by default Outlook 2016 cannot synchronise calendar and address book data with the help of the open standards CalDAV and respectively CardDAV. Because of this, an add-on must be installed to do so.

In the following visual instructions, we use the open source add-on Outlook CalDav Synchronizer. Alternative add-ons can be found in the in-depth guides for address book and calender synchronisation.

How to install Outlook CalDav Synchronizer

The add-on Outlook CalDav Synchronizer can be found on the developers’ Sourceforge page. The download is in the form of a .zip file. Extract (unzip) the file and open the file named CalDavSynchronizer.Setup.msi to install the add-on.

Once the installation has been finished, restart Outlook 2016. You can now use the add-on and set up synchronisation.
