Dear Support Team, Brief on the issue faced: - After reinstalling Thunderbird, (because it keeps asking for password even though I entered the correct password) whenever I compose new emails, my regular client's email address is no longer available. before this reinstalling, it will autosuggest when I tried to type in their email address in the receipent "To" field. I looked at my address book and it contains mostly mobile phone numbers only, very few emails and also my regular clients emails are not there. Question: How Can I get thunderbird to capture/recall all email address in my inbox or outbox so that it can autosuggest or auto-recall in the "TO" field whenever I type in the first few letters of their name or email? Thank you very much in advance!
