Set the E-mail message status to read or unread in Thunderbird, how to?
The solution is quite simple to change the status of the messages e.g. e-mails in Thunderbird as read or unread e-mail!
Thunderbird displays unread message in bold face type! If you want one or multiple selected E-Mail messages set the status as read or unread.
Select the appropriate e-mail in Thunderbird and then simply press the key [M]. At your first keypress the e-mail messages are marked as unread, and vice versa at the Second [M] keypress the status switch's to read. (PS: In Outlook, it was the key combination Ctrl + Q).
However, you can also set the selected Thunderbird emails via right-click to status unread od read.
