Hey there!
The syntax for all four commands:
Get-MailboxFolderPermission -Identity [email protected]:\calendar Set-MailboxFolderPermission -Identity [email protected]:\calendar -user [email protected] -AccessRights Editor Add-MailboxFolderPermission -Identity [email protected]:\calendar -user [email protected] -AccessRights Editor Remove-MailboxFolderPermission -Identity [email protected]:\calendar -user [email protected]
Let’s take a quick look at the calendars permission available to use with the switch -AccessRights
o Owner: The Owner role gives full control of the folder. An Owner can create, modify, delete, and read folder items; create subfolders; and change permissions on the folder.
o PublishingEditor: The Publishing Editor role has all rights granted to an Owner, except the right to change permissions. A Publishing Editor can create, modify, delete, and read folder items and create subfolders

Get calendar permission from all users
Get-Mailbox | ForEach-Object {Get-MailboxFolderPermission $_":\calendar"} | Select Identity, User, AccessRightsBYW, an important piece of advice is if your users have their home language from Microsoft 365 different from English you must change the word calendar to the appropriate translation. In my case, I have a lot of Brazilian users so, sometimes I should use calendário as the folder name.
Remove-MailboxFolderPermission -Identity [email protected]:\calendário -user [email protected]
