Your problem is simple. Access doesn't export to Word (.doc) files. It exports to Wordpad (.rtf) files. (Yeah, I know... it doesn't say that. It lies about other things too.) Access and Word have .RTF as their lowest common denominator. That is the issue in a nutshell. The lowest common denominator is pretty low, isn't it?
There are only two ways I've ever found to avoid this problem.
1. Open Word as an application from Access. Create the document you wanted to create using Automation (formerly known as ActiveX, but that has now taken on a newer meaning.) Put in the data fields, lines, boxes, etc. that way. Egad, what a messy chore. Possible but not for the beginner or the squeamish.
2. Open Access as a data source to Word for a Mail Merge. Create the template Merge document with the boxes, lines, and spaces as needed. Better but still not really good for complex cases.
Access is not a word processor. Do not expect it ever to act like one. If you want a word processor function, launch a word processor.
P.S. - I agree that this treatment of reports sucks. But it is what it is. Only Bill Gates and God (in that order) can change it.
