Outlook for Mac - Google Calendar Interop
Hello! We seem to be having a slight issue where we (Google Workspace) and our sister company (Microsoft 365) have set up Calendar Interop using the Microsoft Graph API connector. Current Setup: Calendar Interop is configured to share free/busy time between Google Workspace and Microsoft 365 users. The interop is configured correctly and working as expected across most platforms. Our Issue: Users on the newest version of Outlook for Mac cannot seem to view the Google Workspace calendars correctly. Instead of seeing free/busy time slots, the entire calendar appears fully blocked out (as if all time is marked as busy). Tested already, and confirmed: OWA — works perfectly, free/busy displays correctly Outlook for Mac in Legacy Mode — works perfectly, free/busy displays correctly New Outlook for Mac — entire calendar blocked out This leads me to believe the interop configuration, permissions, and data are all correct. It almost looks like some kind of rendering issue, perhaps a bug, but I cannot be sure. I am also wondering if this has anything to do with any new security on the newer versions of Outlook for Mac? We are using the Graph API connector (not EWS), which is the recommended way for setting up the interop, but still have this issue. Has anyone else experienced this, or is there a known fix or workaround short of reverting to Legacy Mode? Any help or insight would be greatly appreciated. Thanks in advance!
