Vista - Outlook (Office 2007)

OS: Vista Home Premium SP1

On Monday (6/09) Outlook started crashing my computer. I had not made any
changes to my computer (no new drivers or programs installed).

I restored my computer back to 5/31 and the problem was not solved.

I doubled checked to make sure no new drivers were installed.

I opened several other programs (Word, Excel) included with Office 2007 and
had no problem with them.

I repaired the Office 2007 installation which did not help.

I uninstalled and reinstalled Office 2007 which did not help.

I use CA Security Suite and turned off the Spam portion of the program and
that did not help.

I am at a loss how to trouble shoot this problem. I can easily use another
mail client, but I'd rather not. In addition, I use the calendar in Outlook
extensively and now have no access to the calendar or reminders.

Thank you for your help and suggestions.
