I’ve got multiple email accounts but I actually only use 1 address to send my mails from.
As Outlook always automatically uses the account that the message has been received with for sending as well, I need to change the account each time.
How can I make Outlook always use the address of my default account instead?
There is no option in Outlook to force it to always reply with the email address of your default account; replies and forwards will always use the account that the message has been received with.
However, there are a couple of workarounds which can still make it work.
Method 1: Forward messages on the old server
If these are old accounts and you only have configured them in Outlook to monitor if mail is still received on them, then you could opt to forward your mail to your new email address instead.
Many mail providers offer this option in their web based mailbox.
Since this mail forward or redirect rule runs on the server, there is no need anymore to configure the account in Outlook.
Method 2: Collect messages on the new server
Again, if these are old accounts, but a forwarder on your old address isn’t possible, then configuring your new mail account to collect mail from your old account could be a possibility.
Now you only have to configure your new account in Outlook.
Method 3: Configure Outlook to prompt you for your account when sending
You can configure Outlook to prompt you for the sending account each time that you send a message. Configuring this can be done by changing a Registry setting.
For details see; Always prompt for sending account.
Method 4: Modify your account’s email address and SMTP server settings
As always being prompted can be a pain, especially when you ALWAYS want to use your default account, then you can modify several of your email account settings to match your sending account. This can only be done when these are POP3 or IMAP accounts.
For the non-default account you’ll have to do the following;
- Change the address to the address that you want to send out with.
- Use the SMTP server settings of the email address that you want to send with.
- Set the SMTP server logon information on the Outgoing Server tab of the More Settings… dialog
Assume you have a new email account for firstname.lastname@example.org which you want to use when replying to messages received with the email@example.com account as well. We also assume that the email addresses are the usernames.
In this case you’ll fill out the main account settings for the firstname.lastname@example.org account in the following way;
|Your Name||Robert Sparnaaij|
|Incoming mail server (POP3/IMAP)||mail.olddomain.com|
|Outgoing mail server (SMTP)||mail.newdomain.com|
|Password||password for email@example.com|
You’ll then need to press the More Settings… button and set the following settings on the Outgoing Server tab;
|My outgoing server (SMTP) requires authentication||Selected|
|Log on using||Selected|
|Password||password for firstname.lastname@example.org|
