Frequently Asked Questions

What does the WebDAV (Nextcloud) plugin do in Roundcube?

The WebDAV plugin connects your Roundcube webmail to a Nextcloud (WebDAV) server. It lets you attach files from Nextcloud to new emails, insert share links to Nextcloud files, and save email attachments from incoming messages directly into your Nextcloud storage

How do Roundcube and Nextcloud work together with this plugin?

Roundcube remains your email client, while Nextcloud acts as your cloud file storage. With the WebDAV plugin configured, Roundcube can browse your Nextcloud files over WebDAV, so you can pick files to attach or link in emails, and store received attachments straight into your Nextcloud folders—without leaving the Roundcube interface.

Do I need a separate Nextcloud server to use this plugin?

Yes. The plugin requires access to a Nextcloud WebDAV server. You can either host Nextcloud yourself or use a hosted Nextcloud provider, then enter that server’s WebDAV URL and credentials in the plugin configuration so Roundcube can connect to it
