Outlook calendar (Small calender view) is not showing dates in Bold when there is an appointment

I'm having a little problem in my Outlook 2010 over Exchange 2010 (Windows 7 Enterprise). When I go in my Outlook calendar and then I see the calendar's day, sorted by month (Not the whole big calendar's view), none of the dates with activities are bolded.

On another PC, I created my account in Outlook and it worked.

I tried some Outlook switches with no luck

• Cleanfreebusy
• Resetfolders

Also deleted custom forms, rebooted PC and Outlook but no luck.

Any help will be welcome!

That's because your appointments' Show time as option is set to Free.
Edit the appointment or right-click on an appointment and choose Show time as or Show as and choose any of the following options from the sub-menu:

1.Tentative
2.Busy
3.Out of Office

Now immediately date will be changed BOLD.

Appointment set to Show as Free

Same Appointment set to Show as Busy
