Error Message on PDF files when receiving through email

[SweetBoo]

All of a sudden, several clients are saying they can't open the PDF files I'm sending them, although they open perfectly fine on my end. This has never happened before. Anyone have experience with this? Very frustrating.

They are files created in either InDesign or Illustrator and then saved as a PDF.

Open the files in Acrobat and save with a new name and send those files

• Which app are you using to create PDF files?
• Which PDF reader do your clients use to open them?
• What error messages are they seeing?
• Ideally, the attached files should be saved to user's device & viewed in latest version of Acrobat.

I always save or export them as Adobe Acrobat files from within the program (InDesign or Illustrator).

No idea what PDF reader, as this has never happened before so have never questioned.

Error message says file is damaged and can't be opened.
