Delete domain

[GlobalS]

I cant delete some domains (plesk 6.5 for windows).I recive message:


mailmng failed: COM Error 80004003( Invalid pointer) at execute console command --remove-mailname
------------ This means that I should delete domain in PostOffice?

0: C:\Program Files\SWsoft\Plesk\admin\plib\class.DSMail.php:243 psaerror(string "mailmng failed: COM Error 80004003( Invalid pointer) at execute console command --remove-mailname")
1: C:\Program Files\SWsoft\Plesk\admin\plib\class.PhDomain.php:317 dsmail->delete()

5: C:\Program Files\SWsoft\Plesk\admin\htdocs\domains\domains.php3:174 manager->removedomains(array)

There are no DNS, not domain folder in IIS-they are deleted but how I can delete domain in a plesk list ?
Thanks
