[kronolith] ics Files - write access

[Makeri Kutsonu]

Hello !

I have a question :

We use ics Files (on fileserver) in Thunderbird as Calendar.

The Folder with the ics-Files are shard with "Webdav". The Folder is also
exported as nfs.

Is there any way to use external ics files in Horde 5 / Kronolith - not only
read only - but with write-access ? 

Maybe with a "Calendar-Server", sync to local Calendar... or the like ?

Yes, i read this article :
