Lately I receive the same email twice or several times

Hello,

I get my emails with Windows Live Mail and I'm happy with it.

But lately I receive the same email twice or several times, even days after the first time.

I checked out my Server / web-mail - Bell Outlook - but there seem to be no settings that

address the problem. 

I was also told by Bell support that it is a setting in WLM - we changed it to

"delete messages from server" - now the inbox is always empty there and I can only

see messages only in web-mail in the POP folder.

However - the emails still come in (not always) twice or more .....?

I usually like to have a last resort on web-mail in case I delete an email by accident.

Also-the whole problem never occurred throughout the years even though

WLM was NOT set to 'delete messages from server'

Any suggestions
