Only some e-mail accounts showing in left-hand panel

I am running the trial version and have set up 6 e-mail accounts, however only 4 are displayed in the left-hand panel - the primary account and one other are missing. Is this normal?

Hello,

Possibly it’s caused by wrongly set mail account/s. The email accounts which don’t have the incoming protocol correctly set won’t appear in the list. Please check the server settings in Menu > Tools > Accounts.
