You might need to open the file in Excel and reorder the fields to suit Pmail.

The required order is set out in  the Help files.

I just installed pegasus email and want to import my addressbook from thunderbird. I went to 'addresses' and chose 'import tab-delimited file' , chose the file I exported from thunderbird, and nothing happens. How do I get my address book? I also tried the text file feature as well and nothing happened there either.
