Can't Delete, Can't move items and can't send/receive

[JK]

My outlook had to be terminated due to a hangup. When I
restarted outlook, it had to rebuild the database. After
this occured, when I try to erace an e-mail, I get in
error message stating "messaging interface has returned
an unknown error. If problem presists, restart
Outlook." When I try to move an e-mail I get an error
message stating "Can't Move Item". When my outlook does
a send and receive I get the following error
message "Unkown Error 0x8004060C".

Can anyone help?!?!?!
