PDF is changing all my pdf documents into a word document - My boss sent me a pdf email through outlook and when I try to open it changes to a word document

Hi tinam74565130,

That does sound frustrating! It sounds as though the filename associations have become confused on your computer. You should be able to reset that easily. Here are some instructions:

Please let us know how it goes.

Best,
