Another day another WLM problem from Microsoft.....

Whenever I try to use my Junk Mail button in WLM to delete emails coming from my Outlook.com (Preview) account the button keeps giving me the message :  The selected message(s) could not be moved.  A problem has occurred. Please try again.

The button in WLM works when I use it for host supported email account.  Seems like another bug between WLM and Outlook.com (Preview).

Can anyone help correct this technical issue that has been persisting for weeks please?

Thanks.
