Manage Calendar Permissions in M365 with PowerShell

Managing calendar permissions in Microsoft 365 can be a complex task, especially in larger organizations. Using PowerShell, administrators can efficiently manage permissions to view, edit, or remove access to user calendars. This approach is faster, more scalable, and provides more granular control compared to the graphical user interface (GUI).

In this guide, we will cover how to manage calendar permissions in M365 using PowerShell, step by step. By the end, you will know how to view, add, modify, and remove calendar permissions effectively.

Why Use PowerShell for Managing Calendar Permissions?

PowerShell offers several advantages over the GUI for managing calendar permissions:

• Efficiency: Perform bulk changes or automate repetitive tasks.
• Granular Control: Access advanced settings that may not be available in the GUI.
• Scalability: Easily manage permissions across multiple users or groups.
• Time-Saving: Execute commands faster than navigating through the GUI.

Prerequisites for Managing Calendar Permissions with PowerShell

Before managing calendar permissions, ensure the following prerequisites are met:

1. Install the Exchange Online Management Module:
Run this command in PowerShell:

Install-Module -Name ExchangeOnlineManagement

2. Connect to Exchange Online PowerShell:
Use the following command to connect:

Connect-ExchangeOnline -UserPrincipalName admin@yourdomain.com

3. Administrative Privileges:

Ensure you have the necessary admin rights to manage calendar permissions.

Step-by-Step Guide to Managing Calendar Permissions

1. View Calendar Permissions

To check the current permissions for a user’s calendar:

Get-MailboxFolderPermission -Identity user@domain.com:\Calendar

• Replace user@domain.com with the email address of the mailbox owner.
• The command will display all permissions set on the calendar, including users and their access levels.

2. Add Calendar Permissions

To grant a user specific permissions to another user’s calendar:

Add-MailboxFolderPermission -Identity user@domain.com:\Calendar -User recipient@domain.com -AccessRights Editor

• Replace recipient@domain.com with the email address of the user who needs access.
• Common AccessRights values:
  Owner
Editor

3. Modify Calendar Permissions

To update an existing permission level for a user:

Set-MailboxFolderPermission -Identity user@domain.com:\Calendar -User recipient@domain.com -AccessRights Reviewer

• Adjust the AccessRights value to match the desired permission level.

4. Remove Calendar Permissions

To revoke calendar access for a user:

Remove-MailboxFolderPermission -Identity user@domain.com:\Calendar -User recipient@domain.com

• This command removes the specified user’s access to the calendar.

5. Perform Bulk Operations

For large-scale changes, use PowerShell scripts. For example, to grant Reviewer access to multiple users:

$users = @("user1@domain.com", "user2@domain.com")
foreach ($user in $users) {
Add-MailboxFolderPermission -Identity sharedcalendar@domain.com:\Calendar -User $user -AccessRights Reviewer
}

• Replace $users with a list of user email addresses.

Best Practices for Managing Calendar Permissions

1. Audit Permissions Regularly:

2. Use

Get-MailboxFolderPermission

to review permissions and ensure only authorized users have access.

3. Use Least Privilege:

• Assign the minimum permissions necessary for users to perform their tasks.

4. Document Changes:

• Maintain records of who has been granted or removed from calendar access for accountability.

5. Test Commands:

• Test PowerShell commands on a small subset of users before applying them broadly.

Troubleshooting Common Issues

1.Error: “Access Denied”:

• Ensure you have the necessary administrative privileges.
• Verify the user’s email address is correct.

2. Connection Issues:

• Re-run the

Connect-ExchangeOnline

command.

• Ensure your credentials and network connection are valid.

3. Unrecognized Commands:

• Confirm that the Exchange Online Management Module is installed and up-to-date.
