how to sync icloud to microsoft calandar NOT outlook

Hey VKVKVKVKVK,

You can export calendars from iCloud using the steps in this article: Import or export calendars on Mac - Apple Support

"Export a calendar’s events

You can export an individual calendar’s events to a calendar (.ics) file. You can use this method to share a calendar’s events with other users, back up calendars in the On My Mac section of your calendar list, or import a calendar’s events to another calendar or device later.

1. In the Calendar app  on your Mac, click the calendar’s name in the calendar list.
2. If you don’t see the calendar list on the left, choose View > Show Calendar List.
3. Choose File > Export > Export.
4. Choose where to save it, then click Export.
5. The events can be exported to a calendar (.ics) file only.

Export all calendars

You can export all your calendars at once to a calendar archive (.icbu) file. You can use this method to back up all the calendars in the On My Mac section of your calendar list at once, share your calendars with other users, or import your calendars to another device later.

1. In the Calendar app  on your Mac, choose File > Export > Calendar Archive.
2. Choose where to save it, then click Save.
3. The calendars can be exported to a calendar archive (.icbu) file only."

If Microsoft offers importing of .ics or .icbu files than you can import those into the Microsoft calendar app.

If that doesn't help, we'd suggest checking with Microsoft support for further assistance. You can find their support page here: Microsoft Support

Thanks!
