Windows 7 - setting up multiple accounts in Window Live Mail

Thanks for any help.
The main account is set up and seems to be working.
When I set up the 2nd account. It seems to be ok.
Then I go to another computer and send a message to the
2nd account. I never get the message in the Window 7 puter.
The account is a valid account with my ISP. It does not show
as not accepted by the 2nd computer.

I am sure I have done something wrong....

If the first account is working fine, when I see new accounts not working. I.e. not sending and or not receiving I go through the account set up carefully. Depending whether it is not sending or receiving some setting for incoming or outgoing is not right.

In the properties for each account you must check the box to "include this account when receiving mail synchronizing". If you don't you can still get the mail but you have to click on the account in the sync drop down list.

If WLM is not working properly, try a repair of Essentials via Programs and Features.
