[E2010] [EWSMA] [C#] Convert FolderEntryId to FolderId
-
Friday, October 05, 2012 2:53 PM
I have PidTagWlinkEntryIdfrom "Navigation shortcuts" http://msdn.microsoft.com/en-us/library/ee179467(v=exchg.80).aspx in this "Folder EntryID Structure" http://msdn.microsoft.com/en-us/library/ee217297(v=exchg.80).aspx. How can I convert this to FolderId http://msdn.microsoft.com/en-us/library/dd633930(v=exchg.80).aspx?
When I try to do the following:
var appointments = service.FindAppointments( new FolderId(Convert.ToBase64String(entryId)), new CalendarView(DateTime.Now.Date, DateTime.Now.Date.AddDays(7)));i get this Exception:
[Microsoft.Exchange.WebServices.Data.ServiceResponseException] = {"Id is malformed."}
Any help would be appreciated.
Thanks in advance.

The EntryId you get from that property is the HexEntryId so you need to convert this to the EWSId using ConvertI operation http://msdn.microsoft.com/en-us/library/exchange/bb799665%28v=exchg.140%29.aspx to be able to bind to the folder. So the first thing you want to do is Convert the ByteArray to Hex using BitConvertor eg
AlternateId aiAlternateid = new AlternateId(IdFormat.HexEntryId, BitConverter.ToString(baByteArray).Replace("-",""), "mailbox@domain.com"); AlternateIdBase aiResponse = service.ConvertId(aiAlternateid, IdFormat.EwsId); Folder fld = Folder.Bind(service, ((AlternateId)aiResponse).UniqueId);Cheers
