Integration with webmail


I’m in a “degoogling” process and Nextcloud is what I found to be the best to replace Google Apps. The Nextcloud Mail app however is unusable from my point of view, so I’m using an external webmail for this. As I have a personal e-mail server, I tried SOGO, Rainloop and now I’m using Roundcube.

Roundcube is great for e-mail and I can access Nextcloud Contacts from it. But I couldn’t integrate Nextcloud Calendar so I can accept event invitations from e-mails and automatically add it to my calendar. SOGO has a built-in calendar, but I can’t use Nextcloud calendars in it and the e-mail usability isn’t as good as Roundcube’s.

Does anyone knows how can I achieve this with Roundcube or, maybe, SOGO? I know I can use SOGO’s caldav server instead but I prefer concentrating as much as possible on Nexcloud.

Thanks in advance!

Have you found any other options?
Thank you in advance.

The question about the Calendar plugin for Roundcube is probably better asked here:

However, basically every CalDAV capable calendar plugin for Roundcube should work with Nextcloud. You can search for plugins here:

respectively here:

Unfortunately, I cannot give a recommendation, because I don’t use any of them myself.

I recently saw there was a new NC app available: roundcube. So why not trying this one?

Regardless of if Roundcube is installed or SoGo or what not, it’s usually just a different view/perspective on what information they get from a common mailserver. At the end of the day they are just clients
