I'm sorry about the issue. What is the email program you are using?
What email provider do you use, such as Hotmail, Yahoo, Gmail, AOL, etc.?
To confirm, you only want to use your email on one computer right?
Can we do a remote support session, so I can troubleshoot the issue directly on your computer together with you?
Please reply at the box below. Thank you,
I'm sorry. When you receive new email messages, they come up to all 3 computers. Now you want new messages to only come up to one computer right?
You do not want new email messages to come up to the other two computers right?
