Email Excel Attachment Issue

[Zimmerray1]

Firstly, I apologize if this is not the correct location to ask for help concerning email attachments. However, I don't know where else to pose this question.

My issue is this: Every single time I compose an email and need to attach an Excel file, I get this message:

Clicking on the file that I need to attach attempts to open a new instance of Excel. I then have to choose one of the 3 options and close out the newly opened instance of Excel. It has become very frustrating.
