send/receive email dropdown list gone

[Nancy]

I temporarily moved my outlook over to my laptop. i have about twenty
accounts. i have been sending and receiveing from single accounts one at a
time. but suddenly my drop down list of emails is gone. I go into the
send/receive button or on Tools/SendReceive and it no longer shows all my
emails. Just a few choices including send/receive all. but no email list.

Any ideas? Outlook 2003 on XP

Thanks!
