I don't want to mark emails as read when I have only seen them in preview. How can I do this, so they are only marked as read when actually opened?

more options

every other email client I have used lets me mark a message as read only when I actually double click and read it. and not just when I preview it.

Its not my product. Maybe educate yourself and learn that this forum is staffed by Thunderbird users.

You can set a longer time that you can display the message before it is marked as read but in Thunderbird if you open it in a tab or the message pane you have read it.

The time setting is at ..

Tools-options-Advanced-Reading and Display

No menu bar with tools showing? Press the alt key.

Sorry, that isn't correct. if I set a delay before it is marked as read, even if I explicitly open an email it doesn't get marked as "Read" until that time expires. In Outlook / Live Mail / Hotmail / Lotus Notes, etc. I can set it to show as Unread if I view it in the Preview Pane, but it gets marked as Read if I actually open it by double-clicking or pressing Enter.

Then use Outlook. This is how Thunderbird works. Thunderbird does not have a preview pane. It is the message pane where you open a message instead of opening in a tab.

I will, thanks. It looks like I am keener to use your product than you are for me to use it.

Isn't that like staffing a hospital with patients?
