Outlook 2016显示约会图标甚至是使用EWS API创建的会议

Question

我正在创建约会并与EWS托管API会面，但是，我发现Outlook 2016中的Icon出现错误。

使用msdn示例创建会议`ExchangeService service = GetExchangeService（）;             预约会议=新任命（服务）;

        // Set the properties on the meeting object to create the meeting.
        meeting.Subject = "EWS : Meeting";
        meeting.Body = "Let's learn to really work as a team and then have lunch!";
        meeting.Start = DateTime.Now.AddDays(2);
        meeting.End = meeting.Start.AddHours(4);
        meeting.Location = "Conference Room 12";
        meeting.RequiredAttendees.Add("attendee1");
        meeting.RequiredAttendees.Add("attendee2");
        meeting.ReminderMinutesBeforeStart = 60;

        //// Save the meeting to the Calendar folder and send the meeting request.
        meeting.Save(SendInvitationsMode.SendToAllAndSaveCopy);

        // Verify that the meeting was created.
        Item item = Item.Bind(service, meeting.Id, new PropertySet(BasePropertySet.FirstClassProperties));
        Console.WriteLine("\nMeeting created: " + item.Subject + "\n");`

但是图标就像这样。 这里，以使用API​​创建的“EWS”开头的主题和带有“Outlook”的主题在outlook中手动创建。 Outlook会议有不同的Icon。

此问题的解决方法是什么？

您可以尝试设置PR_Icon_Index属性https://msdn.microsoft.com/en-us/library/office/cc815472.aspx，您应该能够使用扩展属性将其设置为0x00000402以进行单个实例会议。
