Outlook 2016甚至对于使用EWS API创建的会议也显示约会图标

Question

I'm creating appointments and meeting with EWS managed API but however, I found the Icon's appearing wrongly in Outlook 2016.

Creating meetings with msdn example ` ExchangeService service = GetExchangeService(); Appointment meeting = new Appointment(service);

        // 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");`

But the Icons are like this . Here , Subject starting with "EWS" created using API and subject with "Outlook" are manually created in outlook. Outlook meeting has different Icon.

Any workaround for this problem?

您可以尝试将PR_Icon_Index属性设置为https://msdn.microsoft.com/zh-cn/library/office/cc815472.aspx ，对于单个实例会议，应该可以使用Extended属性将其设置为0x00000402。
