Optimized Validation of PST Folder
Aspose.Email for .NET 24.2 lets C# developers enforce container class matching while adding folders to PST files for improved data integrity. The following C# coding sample showcases how to use the newly added EnforceContainerClassMatching property of the FolderCreationOptions class for this purpose:
using (var pst = PersonalStorage.Create("storage.pst", FileFormatVersion.Unicode))
{
// Create a standard Contacts folder with the IPF.Contacts container class.
var contacts = pst.CreatePredefinedFolder("Contacts", StandardIpmFolder.Contacts);
// An exception will not arise. EnforceContainerClassMatching is false by default.
contacts.AddSubFolder("Subfolder1", "IPF.Note");
// An exception will occur as the container class of the subfolder being added (IPF.Note)
// does not match the container class of the parent folder (IPF.Contact).
contacts.AddSubFolder("Subfolder3", new FolderCreationOptions {EnforceContainerClassMatching = true, ContainerClass = "IPF.Note"});

Fetch Category Colors from OLM
With this update to the C# Email apps API, users can access category colors associated with Outlook items stored in OLM files. The following C# code examples provide more reference for users.
Here’s how you can get all categories from OLM storage:
using (var olm = OlmStorage.FromFile("storage.olm"))
{
var categories = olm.GetCategories();
foreach (var category in categories)
{
Console.WriteLine($"Category name: {category.Name}");
//Color is represented as a hexadecimal value: #rrggbb
Console.WriteLine($"Category color: {category.Color}");
}
}

And the following code snippet how to obtain a message category color:
foreach (var msg in olm.EnumerateMessages(folder))
{
if (msg.Categories != null)
{
foreach (var msgCategory in msg.Categories)
{
Console.WriteLine($"Category name: {msgCategory}");
var categoryColor = cat.First(c => c.Name.Equals(msgCategory, StringComparison.OrdinalIgnoreCase)).Color;
Console.WriteLine($"Category color: {categoryColor}");
}
}
}
