Windows live mail errors, can not delete emails

Received emails 5-31-2016 with an error and could not delete the emails, very frustrating.  Logged into Outlook.com and was able to delete the emails.  Took a couple of minutes and several refresh/shutdowns of the Windows live mail, but they are finally gone.  I doubt this problem was unique to me, running Windows 2012, with Windows 7 Pro.  Saw several messages on possible solutions, this was the only thing that worked.
