How to save and edit an Outlook attachment

Locate the attachment on the email and right click on each attachment:
Click on “Save As”
This will bring up a navigation page – save the document in a place where you will be able to find it.
Click on Save
Once saved, go to the place where you saved the attachment on your computer. Open the document in Microsoft Word. If it is in “Protected Mode”, you need to “Enable Editing” in order to make changes to the document.
