Create and Parse Outlook Tasks

Communication is the cornerstone of modern enterprises, enabling efficiency and success. Microsoft Outlook, a widely-used email and scheduling application, plays a vital role in managing communication and tasks. Outlook is known for its effective task management features, and we will help you manage Outlook tasks from PST (Personal Storage Table) files programmatically. In this article, we’ll explore how to achieve this using C# and the versatile .NET library.

.NET API to Manage Outlook Tasks

Aspose.Email for .NET is your key to streamline the process of managing Outlook to-do lists in PST files. The library offers a comprehensive set of features for interacting with PST files, making it easy to work with tasks, read their properties, create new ones, and perform other tasks-related actions. Before diving into the code, you’ll need to integrate the library into your C# project. You can easily obtain it by downloading from the Aspose website or by using NuGet.

Install-Package Aspose.Email

Once the library is part of your project, you’re ready to start coding.

Reading Outlook Tasks From PST

To work with Outlook items stored within a PST file, you must first locate the folder containing them. In this section, we’ll demonstrate how to read these lists from a PST file and identify them using C#. The code below performs the following steps:

  1. Loading the PST file: We initiate the process by opening the target file using the PersonalStorage.FromFile method.

  2. Accessing the Tasks Folder: We obtain the built-in “Tasks” folder where the target items are usually stored within PST files using pst.GetPredefinedFolder(StandardIpmFolder.Tasks).

  3. Enumerating Messages: We loop through the messages contained within the folder using folder.EnumerateMessages().

  4. Identifying Outlook Items: We examine the MessageClass property of each message to identify Outlook items. They have the message class IPM.Task.

  5. Extracting and Using the Item: When an Outlook task is recognized, we extract it using pst.ExtractMessage(msgInfo) and then convert it into a MapiTask object for further processing.

Once you have access to the Task Item, and you can work with it in various ways, such as accessing its properties, updating it, or executing other operations.

Working with Task Items

You can perform a wide range of operations on Outlook tasks, including:

  • Accessing Properties: Retrieve various properties, such as subject, due date, priority, and more.
  • Updating: Modify their properties, for example change due dates or mark them as completed.
  • Creating New Tasks: Generate new Outlook items in the PST file using C#.

Adding new Outlook Tasks to PST

In many scenarios, you’ll need to create new Outlook tasks within your PST file. Aspose.Email simplifies the process by providing a functional set of tools. Below is a straightforward code sample with steps to demonstrate this simplicity:

  1. Load the PST file using the PersonalStorage.FromFile() method by providing the path of the file as a parameter.

  2. Get the Tasks folder from the loaded file using the GetPredefinedFolder() method, passing the StandardIpmFolder.Tasks enumeration value as a parameter.

  3. Check if the folder exists by verifying if the folder variable is not null.

  4. If the folder exists, create a new task using the MapiTask constructor. Set its subject as “New Task”, description as “This is a task created from C#”, start date as DateTime.Now, and due date as DateTime.Now.AddDays(7).

  5. Save the newly created task in the Tasks folder of the PST file using the AddMapiMessageItem() method of the folder.
