I have been looking for one solution how to create a calendar group by EWS Managed API for 2 days , however , it is painful that i still could not figure out how to implement it . Thanks in advance for your help!

I tried to create a calendar group based on https://msdn.microsoft.com/en-us/library/ee217241(v=exchg.80).aspx. but it is frustrated

public void CreateSharedGroup(Operator @operator, string folderName)
{
ExchangeService service = ConnectToService(@operator.Account, @operator.UnionId);

        FolderView fvFolderView = new FolderView(1000);

        SearchFilter sfSearchFilter = new SearchFilter.IsEqualTo(FolderSchema.DisplayName, "Common Views");

        FindFoldersResults ffoldres = service.FindFolders(WellKnownFolderName.Root, sfSearchFilter, fvFolderView);



        ExtendedPropertyDefinition PidTagMessageClass = new ExtendedPropertyDefinition(0x001A, MapiPropertyType.String);



        ExtendedPropertyDefinition PidTagNormalizedSubject = new ExtendedPropertyDefinition(0x0E1D, MapiPropertyType.String);



        ExtendedPropertyDefinition PidTagWlinkGroupHeaderID = new ExtendedPropertyDefinition(0x6842, MapiPropertyType.CLSID);



        ExtendedPropertyDefinition PidTagWlinkSaveStamp = new ExtendedPropertyDefinition(0x6847, MapiPropertyType.Integer);



        ExtendedPropertyDefinition PidTagWlinkType = new ExtendedPropertyDefinition(0x6849, MapiPropertyType.Integer);



        ExtendedPropertyDefinition PidTagWlinkFlags = new ExtendedPropertyDefinition(0x684A, MapiPropertyType.Integer);



        ExtendedPropertyDefinition PidTagWlinkOrdinal = new ExtendedPropertyDefinition(0x684B, MapiPropertyType.Binary);



       ExtendedPropertyDefinition PidTagWlinkEntryId = new ExtendedPropertyDefinition(0x684C, MapiPropertyType.Binary);



        ExtendedPropertyDefinition PidTagWlinkRecordKey = new ExtendedPropertyDefinition(0x684D, MapiPropertyType.Binary);



        ExtendedPropertyDefinition PidTagWlinkStoreEntryId = new ExtendedPropertyDefinition(0x684E, MapiPropertyType.Binary);



        ExtendedPropertyDefinition PidTagWlinkFolderType = new ExtendedPropertyDefinition(0x684F, MapiPropertyType.String);



        ExtendedPropertyDefinition PidTagWlinkGroupClsid = new ExtendedPropertyDefinition(0x6850, MapiPropertyType.String);



        ExtendedPropertyDefinition PidTagWlinkGroupName = new ExtendedPropertyDefinition(0x6851, MapiPropertyType.String);



        ExtendedPropertyDefinition PidTagWlinkSection = new ExtendedPropertyDefinition(0x6852, MapiPropertyType.String);





        var objWunderBarLink = new Microsoft.Exchange.WebServices.Data.EmailMessage(service);

        objWunderBarLink.SetExtendedProperty(PidTagMessageClass, "IPM.Microsoft.WunderBar.Link");

        objWunderBarLink.SetExtendedProperty(PidTagNormalizedSubject, folderName);



        objWunderBarLink.SetExtendedProperty(PidTagWlinkGroupHeaderID, "5BA943D8DAAA462CA63E9136F65C8681");

        objWunderBarLink.SetExtendedProperty(PidTagWlinkSaveStamp, 0x12345678);

        objWunderBarLink.SetExtendedProperty(PidTagWlinkType, 0x00000004);

        objWunderBarLink.SetExtendedProperty(PidTagWlinkFlags, 0x00000000);

        objWunderBarLink.SetExtendedProperty(PidTagWlinkOrdinal, HexStringToByteArray("80"));



        objWunderBarLink.SetExtendedProperty(PidTagWlinkFolderType, "0278060000000000C000000000000048");

        objWunderBarLink.SetExtendedProperty(PidTagWlinkSection, 0x00000003);



        objWunderBarLink.IsAssociated = true;

        objWunderBarLink.Save(ffoldres.Folders[0].Id);



    }
