Question : Error while archiving folder "IPM_SUBTREE"

I am running a Vista system using MS Outlook 2007.  When I try to run "Archive" from the file tab it appears to be archiving but at the end I get an error "Error while archiving folder "IPM_SUBTREE" in store "Mailbox etc.."  It goes on to say it cannot open my archive.pst file.
I have been running this sytem for months using the same archive.pst file.

Answer : Error while archiving folder "IPM_SUBTREE"

Maybe this:

1:	SELECT * FROM table1 WHERE ((adtitle LIKE '%free%') OR (comments LIKE '%free%') OR (adtitle LIKE '%food%') OR (comments LIKE '%food%')) AND active='1';
