I have a Microsoft Word file that has custom page size specified in the layout (specifically width 6.14" height 9.14"). There are also custom margins. When I convert to pdf via File > Print > Microsoft Print to PDF a pdf file is created but the page size is not correct. A pdf file is created that is 8.5"x11" not 6.14"x9.21". After trying to debug and spending 6+ hours with Microsoft tech support, there seems to be a problem on the Adobe side when the Word file is passed to Adobe to be converted into a pdf. I have noticed that it will convert standard page sizes like letter, legal, etc. But it doesn't work for any custom page sizes (I have tried several different sizes as well as Word page document length and the result is the same each time, Adobe always creates a pdf file that is 8.x5"x11").
