Problem with Adobe Files

It sounds so strange, though I do not use the MS Outlook but I am assuming it's quite reliable email client to send/receive any attachments. Just as experiment try out to send compressed pdf file (zip, rar. etc). It won't reduce file size and it brings some inconvenience. But I hope it can make yours sent files readable at all.

Your Adobe Acrobat Reader is probably corrupted. Uninstall it, and install the latest version.

I support this statement as being the best place to start.

Make sure the .pdf is visible in the filename. I have seen many times when the suffix was hidden, and simply adding the .pdf to the filename made the file readable.

Your PDF reader is probably out-of-date, and you need to upgrade to the new reader. Adobe is notorious in making nothing forward compatible. So if you have reader 5, and the PDFs are in Reader 6 format, it sees them as corrupt files. Update your reader.

The file you received is probably a scan soft pdf.file , you need to save the file first. Go back to the folder , right click - open- with adobe file.

if cannot than your ver.pdf maybe an earlier version.

What did I just say?

Sometimes an error message will appear and the file will still open. So are you getting error message for a file that opens? Or error message and the file won't open? If you are getting "Do you want to proceed? option (or the like) answer "Yes," to see if the file actually is unable to be opened. Also, be sure you are not making any naming convention violations. Could you be lacking an update or patch...to adobe or Outlook?

I recently had a simular problem. It was not the reader. Our home office sent me a link to a new ftp site. Several of the pdf files were corrupt. I then logged into our home server and found that the file sizes were larger on the server in the home office than they were on the ftp site. As a test I have the guy in the home office put the files on the ftp site in a zip file first. Then I had him transfer them onto the ftp site in a binary format. The ftp site had an option of binary and ASCII. Almost nothing is ASCII now days except txt files. This proceedure seems to work.
