In their own words
ContactOffice
ContactOffice brings email, calendars, contacts, document storage, and collaboration tools into an online workspace. Its messaging center can consolidate POP3, IMAP, Gmail, and Yahoo addresses, and supports POP3 or IMAP software access and SMTP relay. Calendar functions include shared agendas, meeting invitations, polls, reminders, and CalDAV synchronization. Contacts can hold photos, comments, and access maps, with CSV and vCard imports and CardDAV synchronization. The documents tool supports shared files, collaborative editing, PDF conversion, and WebDAV access. The service supports Android, iOS, Linux, macOS, Windows, and web access, plus synchronization with iPhone, iPad, Android, and other Exchange-capable devices. Global synchronization is limited to paid subscriptions. The maker says data and backups are hosted in Europe, transfers use TLS/SSL, and two-factor authentication is available. The free plan includes 500 MB each for mailbox and documents, 200 address book entries, and no monthly SMS allowance. Paid plans begin at €5 a month, billed for six months.
