@timo I guess it sounds like a feature request. For me logically a 2 way sync between Outlook calendar and Diarium might be a good addition. The entries in Diarium are all on specific days and have one or more data content per day. That is basically what a calendar app like outlook also does. The flavour is of course different, but such a combination would be a good approach in my perspective. The current integration on phone is endpoint based. To view that independent from the device on multiple devices would really be a good feature.
