Ah yes the DS920+. Great machine. Do you have it exposed to the internet or you use it in your lan only? Will also go for the RAM upgrade. Thanks for your input!

Bought from them in the past. Solid people and superb communication.

I assume you have the DS 1621+? Did you use the remaining 2 bays for the SSD Sata cache in read write mode? I’m thinking the same setup but would like to know why u didn’t choose the nvme solution. Also did you see significant improvement? Where? What containers do you use? Arrs?

Exactly. It should be an akonadi issue. I simulated your setup and although in mine also the boxes are unticked themselves, I still can see my calendar events. Kde on Fedora.

So I guess you have korganizer installed and in the configuration you have setup your caldav url?

Then in the taskbar is it the digital clock that you have? If yes then you should have added calendar events and from them clicked the caldav option, correct?

Could you be more specific? Which app do you use for the calendar? Merkuro ? How do you sync, by entering the webcal address ? What do you mean when updating? Merkuro or nextcloud?
