Draft message status is not displayed in Mac Outlook [PST, Aspose.Email .Net]

Aspose.Email Product Family

Hi,

Aspose.Email for .NET version: 25.3.0

When message in pst file created with draft (unsent status) the Microsoft Outlook displays it correctly. But Mac Outlook shows message as normal (like already sent) message.

Code can be reproduced in two ways:
First (main)

        using var pst = PersonalStorage.Create("mail.pst", FileFormatVersion.Unicode);
        pst.RootFolder.AddSubFolder("Inbox");

        using var mapiMessage = new MapiMessage("from@gmail.com", "to@gmail.com", "some subject", "some body");
        mapiMessage.SetMessageFlags(MapiMessageFlags.MSGFLAG_UNSENT);

        var folder = pst.RootFolder.GetSubFolder("Inbox");
        folder.AddMessage(mapiMessage);

Second:

        using var pst = PersonalStorage.Create("mail.pst", FileFormatVersion.Unicode);
        pst.RootFolder.AddSubFolder("Inbox");

        using var mailMsg = new MailMessage("from@gmail.com", "to@gmail.com", "some subject", "some body");
        mailMsg.IsDraft = true;

        using var mapiMessage = MapiMessage.FromMailMessage(mailMsg);

        var folder = pst.RootFolder.GetSubFolder("Inbox");
        folder.AddMessage(mapiMessage);

Could you please take a look? Thanks!

Hello @Ilyaabramau,

This appears to be a client-specific rendering difference. Windows and Mac versions of Outlook don’t always interpret message flags the same way, so the issue is likely related to how Mac Outlook handles draft status, not the PST file itself.
