email mix up?

[christopher]

i have several accounts on my outlook. Two of which are
through optonline.net. Sometimes when I write an email
from my account the reply will end up in my girlfriends
account. I am not sure why this is happening but I was
hoping someone else may have had this same problem and
could help me fix it. Thanks!

you don't say which version of Outlook you're using, or if you have
individual user accounts in Windows, but ...

For Outlook 2002 with 2 email accounts....

In the email you are composing select Accounts from the toolbar and select
which account you want to send from. When the person you're sending to
replies it should be to that account.

Hope this makes sense
