I have lost my mail bookmark

I open eM client and on the left I have only 4 bookmarks.
Calendar
Tasks
Contacts
Widgets

Where is my mail bookmark & how can I get it back?

Was this ever answered? This has just happened to me

Hi John,

Just click with your right mouse button on any of the visible headings in the left column. You will then see a list with the 5 groups you can see. Just mark the relevant groups for you.
