Office 365 Add calendar permissions with powershell

To add permissions on a Exchange Object in Office 365 using PowerShell the cmdlet set-MailboxFolderPermission or add-MailboxFolderPermission can be used.

In this example we add editor permissions for user2 to user1’s calendar. This will enable user2 to edit, add or delete content of user1’s calendar.

set-MailboxFolderPermission -Identity\calendar -user -AccessRights Editor

Note: kalender is the Norwegian Word for Calendar

To bulk add all users in a Tennant as Reviewer to’s calendar run the following cmdlet.

$Users = Get-Mailbox | Select-Object -ExpandProperty userprincipalname
ForEach ($user in $Users )
Add-MailboxFolderPermission -Identity “\calendar” -User $User -AccessRights Reviewer
