Office 2003 to 2007 upgrade?

I am thinking of Upgrading to Office 2007 from Office 2003 and i want to know if that's possible. My friends say that i cant do that and i will have to make clean installation of Office 2007. I don't want to do clean installation because I'll loose Outlook settings, email addr's, etc. So is there anyone who can confirm if it is possible to upgrade from Office 2003 to 2007 without losing anything??

I will like to get an answer for very same question. I have been using Office 2003 and i don't have any issue in using it but if it is possible to upgrade to office 2007 without losing my current Outlook settings, email addresses then i can surely give it a try.

Yes it is possible to upgrade form Office 2003 to Office 2007 without losing any information. I will like to inform you that they both uses same format and you just have to connect your existing PST to the new mail profile. I have tried it out in mt case successfully. If you have any further queries regrading this than feel free to ask.
