Keep Every Employee Aligned, Wherever They Work
Modern teams rely on accurate, up‑to‑date calendars to stay coordinated. But Microsoft 365 shared calendars, room calendars, and public folder calendars don’t automatically sync to the native apps on employee smartphones. That gap creates missed meetings, outdated schedules, and frontline teams operating without the information they need.
CiraSync closes that gap with secure, automated, enterprise‑grade Calendar‑to‑Phone Sync.
No apps to install, no user training required.

Perfect For:
- Frontline and field teams
- Healthcare and emergency services

Why Microsoft 365 Shared Calendars Don’t Show on Phones
The native Apple Calendar app on iPhone syncs Microsoft 365 over ActiveSync – and ActiveSync doesn’t fully honor shared-folder permissions. So a shared team, room, or on-call calendar that appears in desktop Outlook simply doesn’t flow to the native phone calendar the same way. This is a long-standing, widely documented limitation of how native mobile calendars sync over ActiveSync. The common workaround – switching everyone to the Outlook mobile app – breaks Siri and native widgets, and users (especially executives and BYOD staff) resist changing their default calendar
How CiraSync Solves It
CiraSync writes calendar data server-side, directly into each user’s Microsoft 365 mailbox, so shared calendars appear in the native iOS and Android calendar apps automatically. Because the sync runs at the infrastructure level, it survives device replacements, iOS updates, MFA changes, and password resets, and scales from 50 to 50,000 users with no per-device management.
