Are you an “ex user” of Microsoft Outlook….. and are now using Thunderbird…. But missing just that one little folder “Unread Messages”….??
Well; you even can get that one in Thunderbird.
Go to; VIEW – TOOLBARS – CUSTOMIZE – and drag the “view” to your toolbar.
In that spot you can select “Unread”…. and voila…. your Unread Messages will appear…
BUT; do you like to have it as a real folder (like Outlook has it)…?
Click the View toolbar; and select “Save view as a folder”….. with that one – you will make an “Inbox-Unread” folder in your local folders.
