Outlook 如何从Rest Api获取CalendarID作为MAPIFolder.EntryID？

在Com加载项中，我使用：

public static string GetCalendarFolderIDByAppointmentItem(AppointmentItem appItem)
    {
        string calendarID = string.Empty;
        try
        {
            if (appItem != null)
            {
                MAPIFolder mfolder = appItem.Parent as MAPIFolder;
                if (mfolder != null)
                {
                    calendarID = mfolder.EntryID; 
                    //ex CalendarID1: 00000000CE3AA07BAA3BEB4D89D813609D6535A701005B31700ECA323145B82C6A7BBBDCAB4300000000010D0000*
                }
    }

在Web插件中，我使用：

public static string GetCalendarFolderIDByAppointmentItem(AppointmentItem appItem)
    {
        string calendarID = string.Empty;
        try
        {
            if (appItem != null)
            {
                MAPIFolder mfolder = appItem.Parent as MAPIFolder;
                if (mfolder != null)
                {
                    calendarID = mfolder.EntryID; 
                    //ex CalendarID1: 00000000CE3AA07BAA3BEB4D89D813609D6535A701005B31700ECA323145B82C6A7BBBDCAB4300000000010D0000*
                }
    }

结果:

var Base64StringEntryID = restitem.SingleValueExtendedProperties[0].Value;

然后我将Base64String转换为十六进制，以匹配VSTO的entryId格式

//ex CalendarID2: 00000000CE3AA07BAA3BEB4D89D813609D6535A707005B31700ECA323145B82C6A7BBBDCAB4300000000010600005B31700ECA323145B82C6A7BBBDCAB4300000000304B0000

但结果中有不同的CalendarID。那么，还有其他方法可以从Rest Api获取日历id吗？
