Short Answer:
If a calendar says “this computer only” in the Outlook desktop app, then CalendarBridge cannot sync to or from that calendar.
If a calendar is accessible from Outlook on the Web (i.e., it is a Microsoft 365 calendar hosted in Exchange Online) or is accessible on Outlook.com, CalendarBridge can sync your Google Calendar to that calendar, and thus to the Outlook desktop app.
Longer Answer:
First, let’s clarify Microsoft’s confusing “Outlook” branding:
- There is “Outlook” the desktop application that you download and install on your computer.
- There is “Outlook.com,” which is a personal email & calendar service that hosts @outlook.com, @hotmail.com, @live.com, and @msn.com email address (i.e., it’s Microsoft’s version of Gmail).
- “Outlook on the Web” is a web application for accessing Microsoft 365 calendars which are hosted in Exchange online.
Outlook the desktop app allows having calendars that live only on your computer. Such calendars will typically say “This computer only”:
Those calendars live only on your computer and CalendarBridge cannot access them. To sync those calendars you will need software that installs and runs locally on your computer. One free one is CalDav Synchronizer (which CalendarBridge is not affiliated with in any way).
