I will install 2010 Home and Business under Win 7 Home Premium when it comes from Amazon . 2003 is now installed and I would like to have available it on this machine until I get comfortable with 2010. My major use is Word and Excel and maybe Outlook. I understand the old 2003 Outlook will be used rather than the 2010 Outlook. If I uninstall 2003 Outlook (which I use very, very seldom) before I install 2010, will the 2010 Outlook then work? Also, how can I get all of the 2003 Word Templates and customization transferred to 2010. In the case of the templates I guess it would be simply copying those templates to the appropriate 2010 folders but don't have a clue about other customization. (Maybe Win7's Easy Transfer.) I know how to do it for Excel. In my case it is mostly taken care of by using the 2003 Personal XLS. I had a brief encounter with 2007 but didn't like the ribbon one bit so I went back to 2003. I understand 2010 has some ribbon customization features that might make it acceptable to me. I hope so. Thank you very much.
