If your PDF documents are "XFA-based forms", you can convert them into XDP files using "PDF Utility" service.Otherwise, you have no other choice other than creating new templates from scratch.Thanks,Nith

10MB per file is too large. Have you embedded any images with the form?Can you send me a sample template to review its design/coding part?Nith

I think you have to format your date string as 2010-08-22T09:31:23Z  in order to assign it to a DateTime value.Nith
