Office 365 Recurrence ICS not getting Appended

Dear Team,

I am stuck while appending ICS file with recurrence entries to Office 365. I have checked it manually its getting appended. But using code the entries are not visible in Office 365, when i created the same profile in Outlook those recurrence entries are visible. I have tried Aspose.Email version 20.3. Below code is working fine for non-recurrence entries.

Below Code
Appointment calDoc = Appointment.Load(strTempEventsIcs, new AppointmentLoadOptions() { IgnoreSmtpAddressCheck = true });

Aspose.Email.MailMessage calMsg = new Aspose.Email.MailMessage(); //org
calMapiMsg = MapiMessage.FromMailMessage(calMsg, MapiConversionOptions.UnicodeFormat);
MapiCalendar objMapiCalendar = (MapiCalendar)calMapiMsg.ToMapiMessageItem();

MemoryStream memoryStream = new MemoryStream();
bjMapiCalendar.Save(memoryStream, AppointmentSaveFormat.Msg);
calMapiMsg = MapiMessage.FromStream(memoryStream);

Aspose.Email.MailMessage eml = calMapiMsg.ToMailMessage(new MailConversionOptions() { ConvertAsTnef = true });
eml.BodyEncoding = Encoding.UTF8; //added on 9-11-2018, for umlaut characters
eml.SubjectEncoding = Encoding.UTF8;

string strMessageURI = this.Client.AppendMessage(exchangeFolderInfo.Uri, eml); //this.Client is IEWSClient object

I am appending Calendar recurrence entries to Office 365 calendar. So my issue is after using the above code my calendar recurrence entries are not visible in Office 365. Whereas when i sync the same account to Outlook, i can see the recurrence entries.
