How to display the weight of a mail

A few days ago, i could see the weight of a mail. Now, it disappear. How can I display it? Thank you

There are two reasons this may have changed.

  1. In conversation view, the individual size of an email is not displayed in the message list because each item in the list is a conversation. You can disable conversation view in Menu > View > Conversations.

  2. In the default compact layout, the message list does not display the message size. You can configure the massage list to display in single line layout by either increasing the width of the message list to more than 600 pixels, or configure it in Menu > Tools > Settings > Mail > Read > Message List.

Thank you very much for your rapid answer. I found back the size for an email (item-1).
