Question about Outlook Express

I'm trying to copy my email folders, that have built up over the years, into a different system.

Currently they are on Laptop A,  in Windows Live Mail. I would like to transfer them to Laptop B, in Outlook

I've got to the stage, on A, of File/Export Mail/Export Messages/select format to export to.

I then get the message "Windows Live Mail (not responding)". The system then restarts and puts me back to square one.

Is there a simple way to achieve what I'm trying to do?

When I've accomplished this I can retire Laptop A.

we are not able to open the windows live mail, nothing happens after clicking on the desktop icon

**Moved from:  Windows Insider Program / Windows Insider Preview / Performance and maintenance / PC **

I'm getting multiple copies of E-mails in one account only, about 250 each. It started suddenly, nothing has been changed. I can't stop it and still going on. Windows Live Mail 2012.

I can't delete the account, important to me/business related. I have multiple accounts and only one is acting like this.

What should I look for and start with?

Thanks.
