Calendar FreeBusy Coexistence
Share calendar FreeBusy information between any Office 365 tenants, G Suite and Exchange
How it works
When a user wants to know if another user is available, the user creates a meeting request and clicks on the Find a Time tab (Google) to see Free/Busy time. From Microsoft 365, the user will click on “Scheduling Assistant” to see the Free/Busy time. Cloudiway sends the details between the different tenants and updates the Free/Busy display.
Free/busy calendar coexistence works with any number and combination of Microsoft Office 365 tenants, Google Workspace (formerly G Suite) for Business systems and Exchange On-Premises servers.
Whether you’re looking for a long-term utility for calendar free/busy lookup a short-term remedy during mail migration, Cloudiway’s free/busy coexistence tool offers unrivaled functionality in a secure and stable environment — a unique solution in today’s technology environment.
Retrieve Free/Busy Calendar Details with Google and M365
If you’re using Google Calendar, you can use the “Free/busy” feature to see what meetings are scheduled for today and tomorrow. Cloudiway will retrieve the details from Google and Microsoft 365, and let you create events in both calendars.
Sharing Microsoft 365 calendars with Google Workspace is automatic thanks to Cloudiway. You only need to create your connectors for both of your tenants, you can get the list of users and then start the synchronization.
Benefits
Seameless communication between multi-system environments
During Mail Migration
During a migration using Cloudiway’s calendar free/busy synchronization and other coexistence tools, end users can continue working without interruption. When a mailbox is migrated, address books are synchronized, the mail is rerouted, and free/busy time is available at both the source of the migration and at the target.
Coupled with the GalSync, mailforwarding option or the mail routing, Cloudiway offers you a unique coexistence solution during your migration
During Coexistence
During enterprise coexistence, a Free/Busy calendar look-up can continue to be used for as long as coexistence needs to be in place. Some customers use our calendar Free/Busy synchronization tools indefinitely, particularly during mergers and acquisitions. Cloudiway’s Free/Busy tool provides seamless communication, whatever the situation.
What People Says

We have been working with Microsoft 365 for more than 10 years. We have needed to perform Cloud-to-Cloud migrations on many occasions. Cloudiway has always been the perfect partner providing a very valuable product and support”
Víctor M. Salanova
Dirección en Centria Tecnología
All was achieved 24h after the start, 1st time in my career after more than 10 years of migration. Cloudiway takes care of everything, Mail/shared mailboxes/Ressources/Teams/OneDrive, etc. You need one hour of consulting services to be sure everything is well set up before starting, but in a migration budget, this hour is nothing regarding the time you earn after in support issues…
