I have an odd issue being reported by several of my folks with Excel. They fill columns with common colors for whatever reason... upon attaching the file to Outlook both the attached file and the source file are changed. The filled colors convert to a black background pattern, typically the stippling and the fill color is lost. Not a big issue, but it is frustrating several of my users. I've never seen this issue before and didn't find any reports of it when I searched... any ideas? Any help would be greatly appreciated...
