The Update-MgUserTodoList cmdlet in the Microsoft Graph PowerShell module allows administrators to update To-Do task lists for users. This can be incredibly useful for automating task management and keeping lists organized, especially in bulk scenarios. This article delves into the cmdlet's syntax, usage examples, tips, possible errors with solutions, and impactful use cases.

Cmdlet Syntax

Update-MgUserTodoList -UserId <String> -TodoTaskListId <String> -BodyParameter <Hashtable>

Parameters:

-UserId: The unique identifier or UPN of the user whose task list is to be updated.
-TodoTaskListId: The ID of the task list to update.
-BodyParameter: A hashtable defining the properties of the task list to be updated.

Usage Examples

Example 1: Update a Single Task List

This example updates the display name of a task list for a specific user.

$params = @{
    displayName = "Updated Project Tasks"
}
Update-MgUserTodoList -UserId "john.doe@contoso.com" -TodoTaskListId "AAMkAGI2T..." -BodyParameter $params

Example 2: Update Multiple Task Lists

This example iterates through a list of task lists for a user and updates their descriptions.

$taskLists = @(
    @{ Id = "AAMkAGI2T...1"; Description = "Updated Description 1" },
    @{ Id = "AAMkAGI2T...2"; Description = "Updated Description 2" }
)

foreach ($taskList in $taskLists) {
    $params = @{
        description = $taskList.Description
    }
    Update-MgUserTodoList -UserId "john.doe@contoso.com" -TodoTaskListId $taskList.Id -BodyParameter $params
}

Example 3: Bulk Update via CSV

This example updates multiple users' task lists using a CSV file.

$csvData = Import-Csv -Path "TodoLists.csv"
foreach ($row in $csvData) {
    $params = @{
        displayName = $row.DisplayName
    }
    Update-MgUserTodoList -UserId $row.UserId -TodoTaskListId $row.TodoTaskListId -BodyParameter $params
}

Cmdlet Tips

Use Valid IDs: Ensure the TodoTaskListId is accurate, as incorrect IDs result in errors.
Test Before Bulk Operations: Always test updates on a single task list before proceeding with bulk updates.
Adhere to Documentation: Follow the official parameter structure for the -BodyParameter to avoid errors.
Check Permissions: Ensure the account running the cmdlet has the necessary permissions to update To-Do task lists.

Possible Errors & Solutions
