Rated 5 out of 5 stars

Love this! This is one of the add-ons that keeps me working with Thunderbird even though I can't share vcards a requirement for my work. Because of this addon, and a few others I work in both Thunderbird & Outlook. Someday I hope to be able to dump Outlook, but until I can share VCards it's not possible.

This review is for a previous version of the add-on (0.9.9.9).
