Been trying to fix this for about 2 months. A 1000 dollar program on new computer and latest operating system and doesn't work.

    Every time I try to email an invoice. The attached invoice is called moz_mapi-1 .
Even though it can be opened with PDF and is a PDF file.
Have no idea why.
Was working ok a month back.??

Using Reckon accounts Pro 2014.
With windows 8.1 and Thunderbird email program.
