I went to a Thunderbird forum and described my problems, and within 10 minutes I had an excellent download add-on for Thunderbird. I used it yesterday and then used your program and had terrific success. Everything I wanted to move from Thunderbird to Outlook 2010 (except my address book) went just as slick as could be. Thank you very much for your kind offer of assistance. I will be glad to tell others of your and your company’;s good work.
