The exact message is " Windows Live |Mail could not be started. The application was unable to open the Windows Live Mail Message Store. Your Windows Live Mailbox data is currently being used by another program such as a virus scanner. Close the program or wait for it to complete its operation before opening Windows Live Mail again. 0x800C0155, 997

I have closed off any scanners, so how do I check what is using it

Thanks,
