No that’s not possible, except that you can subscribe to an read-only iCal calendar. This has already been discussed here: > [@Syncing NexCloud calendar with external caldav resources](https://help.nextcloud.com/t/syncing-nexcloud-calendar-with-external-caldav-resources/40237): > > Hello All, I just installed NextCloud 14. Since i already run a tine20 groupware solution, with a complete calendar management, i would like not to enter all dates in two systems - it would be much more comfortable to just sync the nextcloud calender with the external tine20 calender using a caldav address. Since NexCloud Calender offer the possiblility to sync clients against caldav i hope it’s not so difficult to let nextcloud calender also be a client for other resources ?? Best Regards Ha… or here > > > It would be nice if the nextcloud calendar and address book were able to subscri…be to other sources, as for example provided by employers or public services like Google. > > A way to "mount" external calendars and address books just like it is possible to mount external storage would be a great way to create a sustainable/hybrid infrastructure. I would recommend to use [Vdirsyncer](https://github.com/pimutils/vdirsyncer) to synchronize your calendar databases. > **[GitHub - pimutils/vdirsyncer: 📇 Synchronize calendars and contacts.](https://github.com/pimutils/vdirsyncer)** > > 📇 Synchronize calendars and contacts.
