I was working with someone who has been migrated to Office 2007. If we create an Excel Spreadsheet and convert it to Pdf all is well. When we do the same with his old files the graphs move to the bottom of the pdf page and any text boxes will change font and the graphs will over run the text. We saved the files as .Xlsm and tried again but to no avail.
You posted your question to the forum comments forum. This forum is for questions about these forums, not for questions about other Adobe products.
I am not sure which product you are having a problem with (Acrobat to convert to PDF? Reader to read the PDF? Or the builtin PDF capability of MS Office?), but if it is an Adobe product you can find the appropriate forum from the list of all forums.
