Get-MgGroupEvent Cmdlet: A Comprehensive Guide

The Get-MgGroupEvent cmdlet in Microsoft Graph PowerShell allows administrators to retrieve calendar events associated with a Microsoft 365 group. This cmdlet is useful for managing and auditing group events efficiently.

Cmdlet Syntax

Get-MgGroupEvent -GroupId <String> [-EventId <String>]

• Key Parameters:
• -GroupId – The unique identifier of the Microsoft 365 group whose events are to be retrieved. (Required)

Usage Example

Example 1: Prompting for Group ID at Execution

Get-MgGroupEvent

Running this command will prompt the user to manually enter the Group ID.

Example 2: Providing Group ID Directly

$groupId = "baf5dfb6-da17-4439-a0ff-6ea7b59d6c5f"
Get-MgGroupEvent -GroupId $groupId

Here, the Group ID is directly specified in the command, allowing for immediate retrieval of events.

Cmdlet Tips

• Ensure Required Permissions

Before running the cmdlet, establish a connection with the necessary permissions:

Connect-MgGraph -Scopes "Group.Read.All"

The Group.Read.All permission is required to fetch group events.

• Retrieve a Specific Event

If you know an Event ID, retrieve it using:

Get-MgGroupEvent -GroupId $groupId -EventId "A12345"

• Filter Events by Date

To filter events within a specific timeframe, use:

Get-MgGroupEvent -GroupId $groupId | Where-Object { $_.start.datetime -ge "2025-02-01"
-and $_.end.datetime -le "2025-02-28" }

• Select Specific Properties

Reduce output clutter by selecting only the necessary properties:

Get-MgGroupEvent -GroupId $groupId -Property "subject, start, end"

Use Cases
