When I tried to delete e-mail from my Junk e-mail folder in Window Live Mail 2011, I got the message "An unknown error has occurred". I deleted one message via my ISP (Shaw.ca) on-line webmail program but this message was still appearing in my on-line Junk E-mail folder in Windows Live Mail even after I re-started Windows Live Mail.

I checked \AppData\Local\Microsoft\Windows Live Mail\Shaw (PaulA 758\Junk E-mail folder and it was empty.

I tried repairing Windows Live Mail via Control Panel\Programs and Features\Windows Live Essentials 2011\Repair but the message headings were still in the Windows Live folder.

I tried going off-line to delete the messages but I still got the "An unknown error has occurred" message.

I suspected that the actual messages may have been deleted from the \AppData\Local\Microsoft\Windows Live Mail\Shaw (PaulA 758\Junk E-mail folder during disk clean-up.

I then:

• Backed up my e-mail
• Reinstalled Windows Live Essentials
• Restored the e-mail backup

The database is now corrupt:

• The folder tree is not the same as prior to the backup/restore
• In some of the sub-folders, the To, From and Subject appear to be correct in WLM but clicking on on each of the e-mails in this folder opens the same message
  

I am using Windows 7. Any assistance would be appreciated.
