How can i do a clean uninstall of outlook?

And i mean 100% clean so that not a single thing that outlook changed in windows 7 is left. Not a single file, no registry entries, nothing. As i said in another thread, my oulook was working find with both email accounts till i messed with a outlook file. Now one of the accounts will not fetch mail from the mail server and i know it's a local issue because 1-it started right when i made that change, and 2-i tried it with outlook on my work pc and it auto configures the account and works perfectly downloading emails like normal. So it's something that happened when i messed with that outlook file and 2 uninstall/reinstalls later it still doesn't work. I deleted all folders after uninstall that i know of, but upon reinstall the accounts still show and my contacts are still there, so i know there are leftover files and of course reg entires. So is there a way to find every single folder,file, and reg entry to delete without deleting anything that is part of the OS that refers to outlook even if it's never been installed on this PC?

Thanks, but i'm very leary of any free software lately thats not something like a MS hotfix or such. Any 3rd party download that looks like it might install adware or toolbar installer or other garbage they install w/o telling you and takes for ever to get rid of i won't touch. Now they are even trying to make them look official. You end up with worse problems than you had before. That site gives me the impression it's one of those. I'm really more interested in a tut on how to do it.

Well, issue resolved and thanks for the idea about a uninstaller THW. I didn't use the one you linked because i thing it was a adware or trial that only works partially or some such thing. But i googled uninstaller and found a free portable one that doesn't install and it worked. I still had to remove some things but the net result was outlook was then abble to auto configure the account and it works now. Thanks.
