Microsoft Calendar Sync
for Personal & Enterprise
Connect your personal Outlook or work Microsoft 365 account and keep your calendars in sync automatically. For organisations, an admin can approve Calendox once and roll it out to the whole team — no setup needed for individual users.

Real-Time Sync
When you add or change an event in Outlook, Microsoft immediately notifies Calendox — no waiting, no background polling. Changes propagate to your connected calendars in seconds. Calendox also automatically keeps this notification channel alive in the background, so your sync stays active without any manual intervention.
Personal & Microsoft 365 — both account types supported

Personal & Microsoft 365 Accounts
Whether you use a personal Outlook.com address or a work Microsoft 365 account, Calendox handles both. Personal accounts connect with a simple sign-in — no IT admin needed. Microsoft 365 work and school accounts open up more: shared mailboxes, meeting room calendars, and Teams meeting links all come through automatically. For larger organisations, an admin can approve Calendox once and give every team member access without anyone going through individual setup.

Microsoft Teams Meeting Detection
If an Outlook event has a Teams meeting attached, Calendox copies the join link into the description of the synced event automatically. Anyone viewing the event on Google Calendar or another Outlook account will find the link in the event details and can click straight into the meeting — no copy-pasting, no separate invites.
