I’m sorry, but I was unable to read the attachment you sent me because you sent it in Microsoft’s proprietary Word (Excel, Powerpoint) format.
Microsoft has been steadily changing the format of their Office documents with every release of Microsoft Office. They have not released the details of these formats, which means the only program that can reliably read the file you sent is the same version of Microsoft Office that you wrote it with (or newer). People with older versions of Microsoft Office, or people who don’t own any version, cannot easily read these files.
This means we cannot exchange information until one of two things happens:
1. the information is sent to me in a standard format that I can read with a program of my choice.
2. I purchase and install the newest version of Microsoft Office (and anything else I need to run it).
Good standard formats to use are plain text, ODF, and PDF (if your document requires formatting information), and I humbly request that you not send Microsoft Office attachments to anybody in the future. Some people might feel that not owning the latest version of Microsoft Office is somehow their fault, and they’re put in an awkward position.

If you’re still using Microsoft Office, do yourself a favour and install LibreOffice.
