I am using Windows 10 Mail, Calendar and ToDo to manage my Xfinity/Comcast email, etc.

I like to backup my data in case I need to restore things.

Can you tell me where the files are stored for the following?

Emails - I think these are stored on the Xfinity/Comcast server so no need to back them up.

Calendar Events - Where are these stored?

Tasks - Where are these stored?

People Contacts - Where are these stored?

Thanks for your help.
