The process of reading messages will vary depend on your webmail client of choice:

Roundcube

You can open a message for reading quite easily in Roundcube. All you need to do is:

  1. Open the Mail task from the main menu.
  2. Select the folder containing the specific message from the folder list.
  3. Click on the specific message from the message list. If you double-click on the message, the folder list will not be displayed, and you will be able to view the message content more easily.

When you read a message, a toolbar will appear at the top that allows you to perform various actions related to the selected message (replying, forwarding, deleting, etc.).
