Greetings.First,I can tell you why the previous thread was locked.Because the topic has been covered many,many times.
Second,what you might be looking for or thinking of is the OWA (Outlook Web Access) threads.It only works with a MS Exchange or Notes servers.That's what is needed to sync calendar functions.(There was an update to the phone last December that was supposed to address this with the built in calendar but being as I don't use Outlook I can't vouch for the validity of that claim.)If your work does not have that ,one option/workaround that might work for you is to install the google calendar plugin for Outlook keep the two synced,and then have it "push" your appts. to your phone using mbCAL. You can get that here(free):
http://instinct-software.com/2008/11/ocdcal/#more-703You could also switch to Google Calendar exclusively or Thunderbird with the Google calendar/Sunbird plugins(free) with mbCAL and get the same effect.That's what I use and it works fine.I get reminders and updating it is easy using the web interface from the phone.It takes getting used to ,but I don't mind it at all.It's only a one way sync(google calendar overwrites the Instinct) but it will get your appt.s to you.As far as your contacts,Sprint backs them up remotely so restoring them is easy(cough).
You must remember that the Instinct is not a "Smartphone" in the traditional business understanding of the word,but rather a multi-media phone with "Smartphone like" abilities.The search function is your friend and with a little time and effort you should be able to find what you're looking for.And sorry to do this,but I'm going to lock this one as well being as it has been covered before(many,many times).

Nothing personal.Good luck and see you around the forum.
