I am running windows 7 and using microsoft office 2010 and can't open emails with pdf files or create pdf files and I need to use pdf for my work. Can anybody help me?
Reader doesn't create pdf files, you need Acrobat for that. What happens if you try to open an email in Outlook? Any error message?
For opening PDF files, you can use the free Adobe Reader, downloadable for example from here:
To create PDF files you could also use https://createpdf.acrobat.com/
