Office365 Calendar - Bulk Editing

Hey folks. We migrated from GSuite to O365 this week and I was curious if anyone has given bulk “Editor” rights using PowerShell to a specific user.

We have an Admin Assistant who previously handled all of our Ministerial staff’s calendars and coordinated planning meetings between all of them. Is there a way to do this from Powershell instead of manually making everyone share their Calendar?

Here is the command I used
add-mailboxfolderpermission -identity user1:\calendar -user user2 -accessrights Editor

Also, does anyone know how to delete the default calendar for a user?
