3 Prerequisites to Run Set-MailboxCalendarFolder in PowerShell

To run the Set-MailboxCalendarFolder cmdlet, certain prerequisites and permissions are required:

• Assigned Permissions: Before you can run the cmdlet, you need to be assigned the appropriate permissions in your Exchange environment. These permissions determine which parameters and actions you can perform with the cmdlet. If you lack the necessary permissions, you will not have access to all parameters or be able to execute the cmdlet at all.
• Calendar Folder Configuration: The cmdlet is used to configure various aspects of a mailbox calendar folder, including enabling or disabling calendar publishing, setting the date range for publishing, choosing the level of detail to publish (such as free/busy information or full details), and enabling or disabling the calendar's published URL for web searches.
• Role-Based Access Control (RBAC): The permissions needed to run this cmdlet are managed through Role-Based Access Control (RBAC) in Exchange. Depending on your role (for instance, Exchange administrator, helpdesk operator), you may have access to different parameters and capabilities.

How to Use Set-MailboxCalendarFolder in PowerShell in 3 Steps

To effectively use Set-MailboxCalendarFolder, you just need to follow three quick steps.

Step 1: Connect to Exchange Online via PowerShell and Review Necessary Permissions

First of all, we need to use the appropriate cmdlet to connect to your Exchange environment. For Exchange Online, use:

Replace your email in the cmdlet, use your credentials, and you’ll be logged into the environment.

Then, ensure that you have the required permissions (which involves determining which roles in your organization can use the cmdlet), and move on to the following step.

Step 2: Identify the Target Mailbox and Calendar Folder

Once permissions are in place, the next step is to identify the mailbox and calendar folder that you want to configure.

If you're unsure of the exact folder name or path, you can list the calendar folders in a mailbox using the Get-MailboxFolder cmdlet. Run this command as follows:

Replace user@meetingroom365.com with the target user's email address and ensure that the folder exists and is correctly identified to avoid errors when running the Set-MailboxCalendarFolder cmdlet.

Step 3: Run the Set-MailboxCalendarFolder Cmdlet with Desired Parameters

Now that you have the necessary permissions and have identified the target folder, you can run the Set-MailboxCalendarFolder cmdlet to configure the calendar folder's publishing settings.

Consider the following example:

This command configures the calendar folder named "Calendar" in the mailbox of user "James" to publish calendar details with limited visibility.

Here’s another example:

This cmdlet enables the calendar folder named "Calendar" in the mailbox of user "simon" to be searchable via its published URL on the web.

After running the cmdlet with your chosen parameters, ensure that the changes have been applied correctly.

You can do this by checking the calendar's sharing settings either via EMS or through the Outlook Web App (OWA).
