Calendar & Contacts
Keeping schedules aligned and customer contact details up to date shouldn't require paying for enterprise email bundles. The ITbox shared calendar and contacts module delivers robust CalDAV and CardDAV synchronization for your entire business. Employees maintain private schedules, book shared company resources (such as meeting rooms or shared vehicles), and access an up-to-date company address book that synchronizes automatically with Microsoft Outlook, Apple Calendar, iPhones, and Android devices.

Why this matters
A shared company address book that stays current
When customer phone numbers and emails are stored on individual employee phones, that data walks out the door when staff leave. A centralized CardDAV address book keeps customer records company property, automatically synchronized across all authorized office devices.
Full calendar synchronization with zero seat fees
Standard CalDAV protocols are supported natively across all operating systems. You get the same scheduling convenience as expensive cloud suites without paying $6 to $18 per user every month.
Who this is for
- Offices needing shared company calendars and team event planning without per-user Google Workspace or Exchange fees.
- Businesses wanting a centralized, shared customer address book so sales and service teams never lose contact details.
- Organizations managing shared physical assets (meeting rooms, projectors, company vehicles) with conflict-free booking.
- Teams wanting private schedule synchronization across all personal and work smartphones.

Technical guide & best practices
CardDAV and CalDAV Open Standards Compatibility
By adhering strictly to RFC 4791 (CalDAV) and RFC 6352 (CardDAV) open internet standards, ITbox calendar and contacts services avoid proprietary vendor protocols. Schedules and address books integrate natively with Apple Calendar, Microsoft Outlook, and open-source email clients without proprietary bridge software.
Resource Scheduling for Conference Rooms and Equipment
Shared physical resources—such as office conference rooms, projectors, or shared company vehicles—can be created as bookable calendar resources. Automated conflict detection prevents double-booking and sends instant acceptance confirmation to meeting organizers.
Best Practice: Native mobile device synchronization
iOS supports CalDAV and CardDAV natively in Settings > Contacts/Calendar without requiring third-party apps. On Android, lightweight open-source sync adapters (like DAVx5) provide seamless, battery-friendly background syncing.
Hardware Specifications
The calendar and contacts module has very low resource requirements. It operates smoothly on the standard ITbox specification (2 cores, 4 GB RAM, 60 GB SSD).
