Thanks a lot. Thanks to your link I've could resolve my problem. For others with the same problem. As I've said, there was no possibility to activate shared calendar in preinstaled calendar application on E1. So I've installed google calendar, there was a passobility to check and activate an shared calendar, so I did it. Now I can use shared calendar in preinstalled original calendar by Sony, and tin the google calnedar too. But this is an issue that Sony should look for. Theer should be possibility to add shared calendar directly in Sony calendar app. Regards.
