PDF file in outlook preview is different than the downloaded PDF

Hi @mrogers442 

Hope you are doing well.

I have a PDF file attached to an email in outlook.  When I preview the file it shows the correct information on the PDF form it has the correct date and everything.  IF I download the file or just open it from the email it shows and older form from 2001.  I have never seen or heard of this before.  Anyone else out there?

This is quite an odd scenario, that file changes back to 2001. 

The possibilities we could think of here,

• When you are previewing the file it's the latest one. but when downloading, it opens the old form. So maybe the new file is overwritten with the old one.
• Click on the drop-down arrow of the attachment and select "Save As". Now save this file to a new location with a new name, not the same name suggested and displayed in the title. 
• Is your default app for PDF viewer Acrobat or Outlook attachment opening on the web directly?

Check with any other attachment pdf. As it could be a problematic file.

Thanks,

Akanchha
