Hello, I am new to Thunderbird and have just installed it in my Win 10 desktop and laptop computers. Emails are downloading simultaneously into both computers but the contacts list aka address book is not synchronized. How can I synchronize the Address Book on both my Win 10 computers?

Thanks very much,

Ken Hanson

The email synchronizing is being done by your email server, not by Thunderbird. Thunderbird is not a synchronizing tool, so the only way to synchronize the addressbook would be to use a synchronizing process, such as using CARDDAV and put addressbook in Gmail. I'm not expert on that, but just two days ago, I helped a user do just that. (He did the work, I just gave him the same suggestion I just gave you.)
