ExchangeSync and WiFi

[dfribush]

Hi -

Apologies if I should post my questions somewhere else.

I just got my first smartphone - an HTC Hero on Sprint.

I have 2 questions.

1. I had no problem setting up my Exchange sync, however I have multiple calendars on my Exchange account (1 account, multiple calendars), but the phone only syncs with one of those calendars. Is there a way to have it sync with ALL the calendars on my exchange account?

2. I can't access my WiFi network because it needs a security certificate. When I go to security certificates in the Android settings it just comes up blank. How do I fix this?

Thanks!!

Dave
