ContactOffice
Brussels, Belgium
What it is
ContactOffice is an online workspace combining email, calendars, contacts, document storage, and collaboration tools. Its messaging center can consolidate POP3, IMAP, Gmail, and Yahoo addresses, with software access through POP3 or IMAP and SMTP relay. Calendar features include shared agendas, meeting invitations, polls, reminders, and CalDAV synchronization. Contacts can hold photos and comments, with CSV and vCard import and CardDAV synchronization. The document tool supports shared files, collaborative editing, PDF conversion, and WebDAV access. ContactOffice runs on Android, iOS, Linux, macOS, Windows, and the web. Mobile synchronization works with iPhone, iPad, Android, and other Exchange-capable devices, while global synchronization is limited to paid subscriptions. The maker says data and backups are hosted exclusively in Europe, transfers use TLS/SSL encryption, and two-factor authentication is available. Each item has individual access rights, and private data is accessible only to its owner by default. A free plan is available; Light costs €5 a month, billed 6 months.
