If I set up a mail forward so that is directed to, and then monitor in Outlook using IMAP, will Outlook (or can it be made to) reply to emails send to as that email?

In other words can I maintain the illusion without the person I reply to randomly seeing references to my gmail account?

EDIT: I was doing some testing... When I sent from AS, Outlook displays the incoming email as " on behalf of". I guess this means gmail's forwarding is not especially useful, is there a workaround? All my POP-based mail is rubbish compared to gmail...

This question came from our site for system and network administrators.

I would be interested in this answer too. As far as I can tell, you can manually choose a different “from” address for outgoing mail, but Outlook won’t automatically choose the correct “from” address. – Nate Jan 6 '10 at 19:40

I came across this same conundrum. The problem on my end was I am using it for business as well and did not think the Gmail looked professional.

The way I had to set it up was to add the email as a POP account in Gmail - Settings->Accounts and Import. Even though I do not use POP to download the message, this gives you the option "Send through SMTP servers (recommended for professional domains)"

This will then use your SMTP servers and will hide any referring information from Gmail. Any mail sent via the Gmail SMTP servers needs to have the "on behalf of" information for spam tracking purposes.

When you reply in outlook you can go to options and add the From field so you can spoof whatever email you want. In fact if you set that in the account properties so it always says you are someone else.

Anyway that is not a server related question...

Which site should it be on, I was not sure? Someone can move to superuser perhaps? – John Jan 6 '10 at 19:41
Yes you can spoof, but can you automate it? You know you'd forget eventually. – John Jan 6 '10 at 19:42
I do not believe you can automate it. I juggle 6 personal and professional accounts through Outlook and yes, occasionally I mess it up, but people seem to be very forgiving on those occasions. – Catherine MacInnes Jan 6 '10 at 20:38

The correct way to do this:

Go to tools > account settings > [select the account that you want to change the sending address of and click "change..."]

In the "Change E-mail Account" popup you want to change the first email address field, and that will be the address that your e-mail recipients will see as the "from:" address.

Now if you don't change the SMTP server from Gmail to your original smtp server for the "" address your sent emails will say from: on behalf of So change your smtp server to the correct one.

Note: You may need to go into "More Settings" > advanced > [and change the outgoing port/encryption].

Note also: If your new smtp server requires authentication, then again in the "More Settings" popup choose the "Outgoing Server" tab and select "My outgoing (SMTP) sever requires authentication" checkbox then select "log on using" option and enter the username and password for the "" account.

Your emails should now appear to be sent from "" even if "" is selected in the reply window.

I had this same issue. I added my company account in gmail from settings>accounts> add pop email; send mail as.

Then in Outlook, under accounts setting, i selected my gmail address and edited the "User Information" email to "". rest every thing, pop, smpt remains the same.

It worked.

Now my email at "" bounces to ""--> outlook download all my emails in gmail and when i send emails from outlook, it is send as ""
