Hi All - I've suffered from this problem a few times and have found TWO
absolute cures.
First cure is to disable McAfee's email virus scan.
Second Cure, which is better, is to access your email at server level, ie -
you should be able to get to your incoming emails via 'Webmail' or similar
provided by your ISP. Once you get to your incoming email source, examine
your inbox items and delete everything that looks even slightly suspicious.
Usually there will be an innocent looking email which is causing all the
problems. Once you delete all these emails, this annoying message will not
appear again - just re-start Outlook and 'Voila'! Problem gone - until some
idiot sends you a similar email.
No need to un-install and re-install McAfee, or Outlook. Just get to your
incoming email source and delete the offending message. If in doubt, delete
them all.
Hope that helps.
