EWS: Finding a default folder

Question

There is an  example here of finding the Conversation History folder on Exchange through EWS:
http://msdn.microsoft.com/en-us/library/hh243707(v=office.14).aspx
However,  the way that it is doing this is by searching for the display name....This won't work for other languages though.  For Exchange 2013, there is a Conversation History has a well known folder name so that can be used, but there is no such
thing for Exchange 2010....
Is there any other way to find the folder (in Exchange 2010) without resorting to name search?

Answer 1

Depending on what version of the Lync Client created the Folder you should be able to search on the FolderClass eg
SearchFilter sfFolder = new SearchFilter.IsEqualTo(FolderSchema.FolderClass,"IPF.Note.Microsoft.Conversation");
FindFoldersResults ffResults = service.FindFolders(WellKnownFolderName.MsgFolderRoot, sfFolder, new FolderView(1));
if (ffResults.Folders.Count == 1) {
Console.WriteLine(ffResults.Folders[0].DisplayName);
