PowerShell is often a more efficient and convenient way to perform tasks, especially when making multiple or frequent changes. This guide provides a quick example of how to manage user permissions in Microsoft 365 Exchange Online using PowerShell.
Whenever the – User “Default” is selected it means that everyone has that permission unless anything else has been set directly to that user.
Note: You can always find the calendar permissions table at the bottom of the page.
This is how you add calendar permissions.

#Add user calendar permissions Add-MailboxFolderpermission -Identity user@domain.com:\calendar -User user@domain.com -AccessRights Reviewer Add-MailboxFolderpermission -Identity user@domain.com:\calendar -User default -AccessRights Reviewer |
This is how you change calendar permissions.

#Change existing calendar permissions set-MailboxFolderpermission -Identity user@domain.com:\calendar -User default -AccessRights Reviewer set-MailboxFolderPermission -Identity user@domain.com:\calendar -User user@domain.com:\calendar -AccessRights EditAllItems |
This is how you remove calendar permissions.

#Remove existing calendar permissions Remove-MailboxFolderPermission -Identity user@domain.com:\calendar -User default Remove-MailboxFolderPermission -Identity user@domain.com:\calendar -User user@domain.com:\calendar Editor |
If you want to change the calendar permissions for all of your users in your organisation you can use the following code to do so.
|
1 2 3 4 5 6 7 8 9 10 11 |
#Choose which calendar permissions to apply for all users, use the table at the bottom. $calendar_permissions = "Enter here" #Enter the domain for your users. $Domain_Name = "domain.com" $users = Get-Mailbox -Resultsize Unlimited foreach ($user in $users) { Write-Host -ForegroundColor green "Updating permissions for $($user.DisplayName)..." Set-MailboxFolderPermission -Identity "$($user.alias)@${Domain_Name}:\calendar" -User Default -AccessRights $calendar_permissions } |
These are the standard permissions you can specify for your users and a short description of what the permission allows.
