In new mailbox are only two basic folders
Spam folder needs to be made visible in Settings on tab Folders.
Other system folders are created automatically the first time you use the functions to which they are bound.
In addition to these system folders the user can manually create folders for sorting incoming mail. Additionally, you can also change the settings of the system folders ( Settings - Preferences tab - Special Folders option), so it can for example save sent mail to another folder.
If you had some user folders in previous version of student e-mail, it's needed to make them visible (Settings - Folders).
