mailbox.org, now branded mailbox, combines email with calendars, contacts and tasks. Depending on your plan, the suite also includes cloud storage, browser-based document editing and video meetings. You can use the web interface or connect compatible mail and calendar apps.
Email connections use IMAP and SMTP, while CalDAV and CardDAV synchronize calendars and contacts. Custom domains, storage allowances and Office features vary by paid plan. The provider describes hosting in Germany; check the current plan details before choosing a package.
