I have Outlook 2007. I have been using it for 6-8 months- no problems other
than my steep learning curve.

The other day my office tried to install "power messaging" onto my laptop.
The corporate email is a web-based Outlook program on an Exchange server. I
wanted my email to be local, not web based. So the tech person, did her
thing, and when she did it, my categories disappeared from my calendar. All
items under those categories disappeared. Some of the categories still exist
under contacts, but all the colors I had associated with the categories are
gone. The only items remaining on my calendar are the ones that I had not
categorized and the holidays and some birthdays. My whole outlook system
seems very disconnected now.

I have over 3 years of appointments/calendar items that are missing. This is
so frustrating.

Any idea how I can go back to before she loaded the email system? (It has
since been uninstalled but all my data is still "missing".) Is there a fix
for this?

Thank you in advance for your time and information!
