Microsoft Exchange Folders.findItems results limited to a 1000

Question

I am trying to get a list of contacts from a contacts folder in microsoft exchange.
the results is only returning a 1000 items even when there is more items in the folder.
Here is my code.

FindFoldersResults r = service.FindFolders(new FolderId(WellKnownFolderName.PublicFoldersRoot), new FolderView(10));
     Folder folder = getFolder("test", r.Folders);
     ContactsFolder contactsfolder = ContactsFolder.Bind(service, new FolderId(folder.Id.ToString()), new PropertySet(BasePropertySet.IdOnly, FolderSchema.TotalCount));        
     FindItemsResults<Item> items = folder.FindItems(new ItemView(contactsfolder.TotalCount));   

how can I get it to return all the items?

Answer 1

I found this article that describes the EWSFindCountLimit setting that might be causing the limit to 1000 items.

This appears to only apply to Exchange Server 2010.
