1. Listing All Calendar Permissions
To start managing calendar permissions, you may want to list all the existing permissions for a specific calendar. Here’s how you can do it:
Get-MailboxFolderPermission -Identity user@example.com:\Calendar
2. Adding Calendar Permissions
To grant access to a user on another user’s calendar, use the following command. This example grants Editor permission to john.doe@example.com on jane.doe@example.com’s calendar:
Add-MailboxFolderPermission -Identity jane.doe@example.com:\Calendar -User john.doe@example.com -AccessRights Editor
3. Removing Calendar Permissions
If you need to revoke previously granted permissions, the Remove-MailboxFolderPermission command can be used:
Remove-MailboxFolderPermission -Identity jane.doe@example.com:\Calendar -User john.doe@example.com
4. Modifying Calendar Permissions
To modify existing permissions, use the Set-MailboxFolderPermission command. For example, changing john.doe@example.com from Editor to Reviewer on jane.doe@example.com’s calendar:
Set-MailboxFolderPermission -Identity jane.doe@example.com:\Calendar -User john.doe@example.com -AccessRights Reviewer
5. Listing Default Calendar Permissions
To view the default permissions for calendars in your organization, use the following command:
Get-MailboxFolderPermission -Identity user@example.com:\Calendar -User Default
6. Setting Default Calendar Permissions
You may want to set default calendar permissions for all users in your organization. For example, granting Reviewer access to the Default user:
Set-MailboxFolderPermission -Identity user@example.com:\Calendar -User Default -AccessRights Reviewer
7. Viewing Calendar Permissions for All Mailboxes
To get a comprehensive view of calendar permissions across all mailboxes, use the following script:
$mailboxes = Get-Mailbox -ResultSize Unlimited
foreach ($mailbox in $mailboxes) {
Get-MailboxFolderPermission -Identity $mailbox.UserPrincipalName":\Calendar"
}
8. Exporting Calendar Permissions to a CSV File
To document calendar permissions, you might want to export them to a CSV file. Here’s a script that exports permissions to a CSV file:
$mailboxes = Get-Mailbox -ResultSize Unlimited
$permissions = @()
foreach ($mailbox in $mailboxes) {
$permissions += Get-MailboxFolderPermission -Identity $mailbox.UserPrincipalName":\Calendar"
}
$permissions | Export-Csv -Path "C:\CalendarPermissions.csv" -NoTypeInformation
9. Adding Calendar Permissions for Multiple Users
If you’re looking to add calendar permissions for multiple users, use the following script:
$users = "john.doe@example.com", "jane.doe@example.com"
foreach ($user in $users) {
Add-MailboxFolderPermission -Identity $user:\Calendar -User another.user@example.com -AccessRights Editor
}
10. Removing Calendar Permissions for Multiple Users
Similarly, you can revoke permissions for multiple users with the following script:
$users = "john.doe@example.com", "jane.doe@example.com"
foreach ($user in $users) {
Remove-MailboxFolderPermission -Identity $user:\Calendar -User another.user@example.com
}
And there you have it! With these PowerShell commands, you can efficiently manage calendar permissions in Office 365, ensuring that your organization’s scheduling and communication are streamlined and secure.
