connection problems after returning from screen saver

[Mike]

When I leave Outlook 2002 running in Windows XP, and
return to the logon screen, Outlook times out while
checking for new messages.

I have 2 email accounts setup. One is Hotmail the other
is Verizon.net. The hotmail account goes offline and the
verizon account can't connect to the server.

To solve this, I have to exit outlook and restart the
program.

Any ideas what is causing this and how to fix it?

Thanks.
