mapi error can't publish new contact form

When I try to publish a new contact form, i get an error message that says
MAPI error, can't find the object. I have uninstalled and reinstalled outlook
twice, the second time after deleting all contacts and still get the same
message, in fact, it's as if I had never uninstalled outlook at all. I know I
somehow deleted something very important but I don't know what or how to find
out and get it back. I tried looking in 'regedit' and 'config' but I'm so not
technical that I had no idea what I was looking for. Please help. Thank you.
