After searching around the KB and community, there seemed to be no clear indication how many calendar group a user/email can create within their account.

 

For an example, microsoft outlook can create multiple calendars and allow a person to share Calendar A with user 1, 2 & 3, Calendar B with user 4 & 5 while Calendar C is not being shared to anyone while merge 3 of them in the owner's viewing list.

 

Another example, Google Calendar shows only one calendar but allow users to create multiple calendar group and share individual group with different people.

 

So, my question is, can a user create multiple calendar group like microsoft outlook calendar or google calendar?
