I'm trying to upload a PDF to email, which I've done many times before. The PDF is under 5 MB (2.6 MB), and opens fine in Adobe Acrobat, yet I keep receiving the error message that it failed to process the PDF. I tried resaving the file, renaming the file - nothing has worked. Has anyone else run into this?
