Managing Calendars with PowerShell in Office 365: A Comprehensive Guide

As an Office 365 administrator, managing calendars efficiently is crucial for maintaining smooth operations within your organization. PowerShell provides powerful tools to streamline calendar management tasks. In this comprehensive guide, we’ll explore various PowerShell commands and techniques to effectively manage calendars in Office 365.

Connecting to Exchange Online

Before we dive into calendar management, let’s start by connecting to Exchange Online using PowerShell. Open a PowerShell session and run the following command:

Connect-ExchangeOnline

Follow the prompts to enter your credentials and authenticate.

Retrieving Calendar Information

Let’s begin by retrieving calendar information for a specific user:

Get-MailboxFolderStatistics -Identity "user@domain.com" -FolderScope Calendar | Format-Table Name,FolderType,ItemsInFolder,FolderSize

This command will display the name, folder type, number of items, and size of the calendar folders for the specified user.

Creating a New Calendar

To create a new calendar for a user, use the following command:

New-MailboxFolder -Parent "user@domain.com:\Calendar" -Name "Project X Calendar"

This creates a new calendar named “Project X Calendar” under the user’s main Calendar folder.

Managing Calendar Permissions

Calendar permissions are crucial for collaboration. Here’s how to set calendar permissions for a user:

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

This grants Editor permissions to “colleague@domain.com” for “user@domain.com”‘s calendar.

To view existing permissions:

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