I don't use Thunderbird, but it sounds like you may have 2 accounts set up. Look through it's settings or preferences options for account management (or some similar verbiage)

You export them from the computer they are on now and import the in Thunderbird on your home computer. To export or import in Thunderbird you open the address book, click on tools then export or import. Thunderbird will use .ldif, comma separated or tab delimited files.

This happened to be to an organization and I only know one of the people personally. The address for the one that didn't go was given to me and now I know it was given to me incorrectly. An O instead of an A in the name. I wanted to know for sure if the other two were sent, and now I know they were. Thanks to both of you for the replies. Sue

I finally phrased my question so that Google found a similar query and solution (from 2006) that still worked 8 years later! In case this might help another user, here are the step from the Moderator at MozillaZine. âÂÂClick on the imported address book name in the left hand pane. Now click on any name in the right hand pane and then use menu path Edit->Select All, or press Ctrl-A. Now drag and drop the data from the imported address book to the Personal Address Book. Once you have confirmed that everything has copied over properly you can delete the imported address book.â I would add that this didn't work smoothly until I deleted special lists/groups. Once they were removed, the whole address book previously under the âÂÂThunderbird Addressesâ name quickly and correctly transferred to âÂÂPersonal Address BookâÂÂ. I'm a happy camper.
