goto 'administrative tools' in the control panel. click 'services', then scroll down to 'Windows Firewall/Internet Connection Sharing (ICS)'. what does it say to the right of it?
now double-click it. a window should pop up with different tabs. if you are not sure what the settings are, then don't change any and ask first. it should say it's startup type= automatic and service type=started. also, look under the dependencies tab for the dependent services and make sure they're started as well. also, under the recovery tab, change the failure options to 'restart the service'

The only way of doing that is with an Exchange Server, not much help but try googling sharing a single PST file... there are programs out there that do this although 2007 is so new I'm not sure how well it work.
EDIT: you might be able to setup say your account first in Outlook 2007, this will create the PST File. You then move the PST file to a central folder (close outlook first...or you get an error message) then go into wife's Outlook setup the account then close outlook, go into Control panel > Mail and add the central PST file then select it as the default email location then remove the useless PST file leaving yours. Might work although i ahve a feeling it will crash or complain or you'll get a lot of duplicate emails as each one of you checks the same email account.
My advice, just share one user account with your wife and store everything in there or get seperate email addresses, you'll have less headaches with this. Also another huge problem with mutiple user accounts on one PC... spyware infests each one individually making it really hard to remove...

I use outlook 2007 so under account setting -> data files you will see your profile and .pst file that holds all your data. So copy that PST on somewhere else.
Create folder on your c drive and share it and right click on it and give permission and make sure you give full permission (so at this point you both can read from that folder). Now put that copied .pst file on this folder.
Go back and logon as you and open outlook and account setting and data file location and add this shared folder .pst and disconnect under your profile.
Repeat same step for your wife and test email. It will work as long as either one of you is using that PC at a time!
