When we got new computers at work, we had to switch to Thunderbird e-mail. After our new computers were uploaded with our old computers data, I noticed I now have 4 duplicate copies of each e-mail address in my address book. Is there an easier way to remove the duplicates other than manually selecting each one?? I have over 600 e-mail addresses in my address book and now there are 4 more of each. This will take forever to manually delete them.
