How to access Yahoo! Mail using Microsoft Outlook
You can use Microsoft Outlook with many email accounts. Most Email providers such as Google’s Gmail, Microsoft’s Hotmail and many other providers provide free POP and SMTP access which allows you to use and integrate all your Email Accounts using Microsoft’s Outlook Express. The only exception is Yahoo’s Yahoo! Mail. In this day and age it is really unfortunate that Yahoo does not provide free POP and STMP access to the users of its free Yahoo! mail.
Note: Yahoo does provide free POP and SMTP access to its premium Yahoo! Mail Plus which requires a paid subscription. If you are one of those who has a Yahoo! mail Plus account, scroll down to the bottom of this article on how you can access Yahoo! Mail using Microsoft Outlook.
How to access Yahoo! Mail using Microsoft Outlook
Step 1: Download YPOPs
You need to download a small application called YPOPs. YPOPs is an application that provides POP3 and SMTP access to Yahoo! Mail. YPOPs acts as a gateway between Yahoo! Mail and Microsoft Outlook. For those who opted for the new Yahoo Mail beta are good too to use this to access Yahoo! mail using Outlook. Download YPOPs from SourceForge.
Step 2: Install YPOPs.
When configuring YPOPs, while the default settings are pretty good, I like to customize them a bit.
* In Receiving Email, under download Email Category, I choose to select just Unread email to download so that I won’t download all the hundreds of emails I have.
* In Sending Email, I check Save email in Yahoo’s Sent Items Folder
* In Miscellaneous, it is good to check Automatically start YPOPs! when Windows starts so that you don’t have to worry about launching it everytime you launch Microsoft Outlook.

Step 3: Configure Microsoft Outlook to access Yahoo! Mail
* For Microsoft Outlook 2003, Go to Tools –> Email Accounts. Select Add a new email account. Click Next. Check POP3 and click on Next
* For Microsoft Outlook 2007, go to Tools –> Account Settings and under Email click New… Under Add a new Email Account select Microsoft Exchange, POP3, IMAP, or HTTP. Then under Add new Email account, check Manually configure server settings or additional server types
* Type your name under Your Name
* Type in your Yahoo! Mail address under Email Address which is the full youremail@yahoo.com
* Under Incoming mail server (POP3) type in localhost. (If localhost does not work type in 127.0.0.1 instead)
* Under Outgoing mail server (SMTP) type in localhost. (If localhost does not work type in 127.0.0.1 instead)
* Under Username type in your Yahoo! Mail address. For example if your email address is asmith2233@yahoo.com, then type in asmith2233. Enter your Yahoo! Mail password and check remember the password

* Click More settings. Under Outgoing Server tab check My outgoing server(SMTP) requires authentication
* Click OK and then Next and then click Finish

I also am having the error message “554 mailbox is unavailable” with Outlook 2007 and Ypops. This is very flustrating as I am trying to combined my work and home.. Please help
home addy is leighanetta@blomand.net
work addy is lindalefevrecpc@yahoo.com
It still work sending emails out but you have the hastle of testing it out 3x before it works. just go to tools>options>mail setup tab>email accounts>repair>tick the manual configure settings>next>test account settings 3x…till you get both sending and outgoing process check marks.
i follow the above step but still unable to access my yahoomail through Oulook 2003, below message prompt out:
Task ‘xxxxxx@yahoo.com - Receiving’ reported error (0×80042108) : ‘Outlook is unable to connect to your incoming (POP3) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).’
may i know why?
For all those who are having problems with sending email should see the window above, with caption “Change Email Account” there at the right bottom you’ll find button “More Settings…..” click that, select advanced tab and click the check box saying “My outgoing server (SMTP) required authentication” also under that, if not by default, click radio saying “Use same settings as my incomming mail server”. You should not have any problems with sending emails anymore.
I also have a problem though, under Configure YPops window I click Unread under “Download Email Category” but still I receive all the emails in my inbox. I am using Outlook 2007. I didn’t see anyone replying to queries of others here but since I am out of options I’m posting my problem with hope that if some one know the solution, I’ll be helped.
I have tried all of the above suggestions and nothing works. I continue to get the 554 cannot send error message. Please help!
Thank you so much! I was always getting so frustrated trying to set up outlook, as all my email accounts are from yahoo. That download worked!
Thanks so much! This really helps

If you are recieving the 554 error, I may have a solution. After spending some time playing with outlook 2007 and ypops, I realized you don’t need ypops to grab email from a yahoo free mail account. If you use pop.mail.yahoo.com and smtp.mail.yahoo.com as your outgoing/incoming servers it will grab your mail. It worked for me. I also removed ypops to see if it would work and it still does.
Hi Aaron, thaks by your comments but actually is working your configuration just to rocketmail and ymail, for yahoo.com is necesary the Ypops.
Thanks,
Rodolfo.
Outlook 2007, and Yahoo! Classic without a glitch using Ypops. It stopped working properly yesterday and just updated to YPOPs!/Windows 0.9.6 Alpha 1 this morning. Outlook 2007 still could not receive or send messages. I went to the Yahoo! website and swiched it from “Classic” to “What’s new?” version. I was able to receive messages but not send them. It read “Your outgoing (SMTP) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: 554 Mailbox unavailable.”
I went back to Yahoo! and switch from the “new” vesion back to “Classic”. . . . Outlook 2007 is working like a charm!
Hope this helps
Thanks Mike.. that worked perfectly. I guess a lot of people had problems since Yahoo switched their interface. So it is a matter of profile corruption.
np like Dan mentions .. it could be corrupted profiles. I would recommend that if ypops used to work for you, I would recommend deleting your yahoo profile in outlook, get the latest ypops and then follow my earlier suggestion of classic interface. It should work for you guys.
Props to you guys @ Askstudent too..
I know this isn’t related to the article, and I’m sorry, but I had to say something about it.
The poll on the right side of the page asked for my “gender”.
Unfortunately, humans do NOT EVER under ANY CIRCUMSTANCES have “gender”. Nouns have gender in languages like Spanish. People are described with the attribute “sex”. Therefore, the question should be “What is your sex?” or “Which sex are you?”
doesnt work on me dear
When you set up a pop3 account with yahoo with a screen name that you have had for 10 years and you decide that you no longer want to receive mail or have a public profile available can this be possible meaning if anyone was to email me it would be returned except for people knowing my pop3 address? Would someone explain this process to me?
I am using ypop3 with microsoft outlook 2007 and receive error msg 554 mailbox unavailable.
please advice how to resolve this
I am using Outlook 2007 for yahoo free mail without ypops and it works just fine. ypops and outlook 2007 don’t seem to work well together. I haven’t had any problems. I am not using ypops at all; it’s not even installed. Just give it a try.
for incoming and outgoing servers use the following:
pop.mail.yahoo.com
smtp.mail.yahoo.com
hey i am getting this error message sent test e-mail: unable to send test message.
if i use account google how to do ?
Still having an issue sending emails; w/ Outlook 2003; can receive just fine though;
Have one email account setup as localhost w/ ip #’s for server identifications (127.0.0.1)
Checked (Outgoing server requires authentication) and use same settings as incoming mail server
Connection: use local area network
Outgoing server set to 25 in advanced tab
Same msg as others: 554 Mailbox not available and the following recipient cannot be reached …
Also - not sure how to configure Ypops; does that have to be done during the install?
Thanks,
Mark
