installation, My default account doesn't match the reply accounts button

1. "REPLY" doesn't use default account name.

I reply to an e-mail addressed to me.
The reply is from my wife.  I am the default account.
I can't find any place to change this.

3. reply mail account not default account

I have 2 e-mail accounts set up on outlook 2003, one is 
set as default, however when I reply to mails and forward 
mails, my other e-mail account always is the one that it 
says the mail is being sent from, Can this be stopped?

5. when replying default account is used instead of the account received on

Hi

I have setup several email accounts and message rules to filter mail to 
specific folders which all works fine.

But recently I've noticed when replying to some messages, my default email 
account is used instead of the one the message was sent to originally.

It seems a little inconsistent - some are ok and the correct account appears 
in the FROM box.

Any idea what might cause this and suggestions for a fix?

The only thing I can think of is that I have a multiboot system with three 
instances of Win XP Pro which all share the same message folders. Maybe 
something's got a bit upset there?

Thanks for any info

Ian

6. several accounts: default account is not defaulted, why? - Outlook Express

7. eMail default reply from account not set as default

Using Outlook 2007. Our ISP changed eMail addresses, so I have 2 accounts 
(old, new).  Receive eMails on both accounts.  New accounts is set as default 
(so all new eMail messages originate from new account).

Problem is that reply to eMail messages are all sent from old account, and 
not new.  Obviously I would like to transition out of all old address eMails.
