Create calendar for an office 365 group

Question

I am using SharePoint Online (modern) from Office 365. I have a publishing site.

I want to add a calendar web part, but there is no calendar for my SharePoint group:

"Something went wrong
We couldn't find a mailbox for this recipient. Either they don't have a mailbox or don't have a license assigned."

Is there a way to create such calendar, or some other solution for calendar sharing within team (we want to share holiday absences)?

Answer 1

You can add a standard traditional calendar with Add an app. It is called calendar. Said calendar can be synchronized with everyone's outlook.
