- Real Time Sync
Calendar Syncing
When an event is created or updated on one calendar, CalendarBridge automatically creates or updates a corresponding event on your other calendars, keeping your availability accurate across every connected account. Avoid double bookings, ensure others always see when you’re actually available, and choose exactly what information is shared, from simple busy blocks to full event details. Works with Google Calendar, Microsoft 365, Outlook, and iCloud.
- All in One Calendar
Unified Calendar
View all of your connected calendars in a single interface to instantly understand your availability, identify conflicts, and manage your schedule without switching between accounts. Create, edit, and organize events from one view, customize which calendars are visible, receive notifications in one place, and keep everything synchronized automatically.
- Booking Links
Scheduling Pages
Share a scheduling link and let others book available time directly on your calendar. CalendarBridge automatically checks availability across your connected calendars to help prevent double bookings, while supporting multiple booking pages, personalized booking experiences, and optional virtual meeting links.
- Automate Scheduling
AI Scheduling Assistant
Connect your assistant to Google Calendar, Microsoft 365, Outlook, or iCloud and let it handle scheduling directly within your email conversations. It can check availability, propose meeting times, coordinate attendees, schedule and reschedule meetings, and manage your calendar on your behalf, eliminating hours of back-and-forth emails every week.

Built for People Managing More than One Calendar
Core Use Case: Prevent Double Bookings Across Calendars
Most scheduling mistakes happen when your availability is split across work, personal, and client calendars. One calendar says you’re available while another says you’re busy. CalendarBridge keeps calendars aligned so you always know where you’re supposed to be, others see accurate availability, and private meeting details stay private.
- Accurate availability everywhere
- Share availability, not event details
- Reduce calendar management effort
- Works across Google, Microsoft 365, Outlook, and iCloud
Consultants & Fractional
Work inside multiple client environments without exposing confidential information. Share accurate availability across organizations while keeping client meeting details private.
Cross-client scheduling visibility
Executive Assistants
Keep executive availability accurate across assistants, organizations, and calendars without constantly checking multiple systems.
Full visibility into availability
Built for Complex Organizations
Tenant Migrations
Keep teams aligned during Microsoft 365 and Google Workspace transitions.
Mergers & Acquisitions
Help newly combined teams coordinate before broader IT integration is complete.
Complex Org Structures
Coordinate across subsidiaries, sister companies, consultants, and external stakeholders.
Core Use Case: Keep Teams Moving During Organizational Change
When organizations grow, merge, or work across multiple tenants and systems, availability becomes fragmented. Teams rely on email chains, assistants, duplicate holds, and manual coordination just to find time together, creating delays and operational drag.
CalendarBridge provides real-time availability visibility across Microsoft 365 and Google Workspace environments while maintaining privacy controls and respecting organizational boundaries.
Privacy-first visibility
Cross-tenant scheduling
Works before migration
Reduce operational drag

Google Calendar, Microsoft 365 for Business*, and Microsoft personal accounts (outlook.com, hotmail.com, live.com, and msn.com), and iCloud.
For many other calendar providers, syncing from those calendars can be achieved using a .ics link to the calendar.
*Unfortunately Microsoft 365 personal and family plans do not include an Internet-accessible calendar and cannot be supported. Supported Microsoft Plans:
- Exchange Online Plan 1 or 2
- Microsoft 365 Business Basic, Standard, or Premium
When syncing from a Microsoft or Google calendar, syncing is real-time — changes to the source calendar will typically propagate to the destination calendar within a minute or two.
When syncing from an iCloud or Internet (.ics URL) calendar, syncing occurs every 5 to 10 minutes.
No. CalendarBridge will sync all events on your calendar starting from the month in which you create the sync connection.
In short, sharing your calendar only lets you see the shared calendar — when colleagues in your organization check your availability (via the Outlook Scheduling Assistant for Microsoft organizations or “Find a Time” for Google organizations), the shared calendar will not be reflected. By using CalendarBridge to sync your availability directly to your primary calendar, colleagues will see your accurate availability in the Outlook Scheduling Assistant and Google Find a Time.
Only if you want them to. This is one of the biggest benefits of syncing with CalendarBridge – you can sync as much or as little information as you want.
If you choose to sync only “busy” then even someone who has direct access to your work calendar will not get no information about your other calendar.
CalendarBridge syncing and scheduling pages are complimentary.
Syncing makes sure each of your calendars reflects your aggregate availability across all your calendars. So when you or your colleagues look at your calendar in Outlook or Google calendar, the availability shown there reflects all of your calendars. In sum, syncing makes it easy for you and internal colleagues to know your true availability.
Scheduling pages, on the other hand, are primarily for scheduling meetings with people outside of your organization(s). Simply connect your calendar(s) and set rules for when you are available to meet and then others can just go to your scheduling page and set a meeting at a time that will definitely work for you — without having to email back and forth with them.
Yes, we offer group plans that provide centralized billing, transferable licenses, and also the option to have administrators directly mange syncing on behalf of their users (i.e., sync end-user calendars without end users having to do anything). See our Group Admin documentation for more details.
A CalendarBridge trial is risk free -- no credit card is required and if CalendarBridge doesn't meet your needs, simply delete your sync connections and we will remove all the event copies we created; leaving your calendar exactly as we found it.
