I can't open my yahoo mail

Hi, follow the steps below. Don't change any of your settings since they already work, but when you get to step 7 this is where you check whether or not you want to remove the emails from the sever.

Open Outlook 2003 then:

1. Click Tools ' E-mail Accounts.
2. Select Add a new e-mail account and click Next.
3. Select POP3, then click Next.
4. Enter the following information:
   • User Information
     • Your Name: Type your name as you'd like it to appear when you send an email message.
     • E-mail Address: Type your Yahoo! Mail Plus email address (for example, [email protected]).
   • Server Information
     • Incoming mail server (POP3): Type pop.mail.yahoo.com
     • Outgoing mail server (SMTP): Type smtp.mail.yahoo.com
   • Login Information
     • User Name: Type your Yahoo! ID (your email address without the "@yahoo.com").
     • Password: Type your Yahoo! password.
   • Check the Remember password checkbox if you don't want Outlook to prompt you for your password each time you check your mail.
   • Do notcheck the Log on using Secure Password Authentication (SPA) checkbox.
5. Click the More Settings button. The Internet E-mail Settings dialog box appears.
6. Select the Outgoing Server tab:
   • Check the My outgoing server (SMTP) requires authentication checkbox.
   • Make sure that Use same settings as my incoming mail server is selected.
7. Select the Advanced tab:
   • Under "Incoming server (POP3)," check the This server requires an encrypted connection (SSL) checkbox. The number in the "Incoming server (POP3)" field usually changes automatically from 110 to 995. If it doesn't, type 995.
   • In the Outgoing server (SMTP) field, type 465. Under it, check the This server requires an encrypted connection (SSL) checkbox.
   • If you want to save your Yahoo! Mail messages on both the Yahoo! Mail server and on your computer, check the Leave a copy of messages on the server checkbox. If you want your messages to be deleted from the Yahoo! server once Outlook has downloaded them onto your computer, leave the box unchecked.
   Note: After your messages are deleted from the server, we cannot retrieve them.
   
8. Click OK to close the Internet E-mail Settings dialog box.
9. Click Next and then Finish.
10. Close and restart your Microsoft Outlook.

Here are the settings for that: https://help.yahoo.com/kb/SLN4724.html

Good luck

Try opening your email from another working computer. The message is telling you that it cannot find the server "mrd.mail.yahoo.com". I am not sure where you are located, but the incoming server for yahoo email is typically just: mail.yahoo.com or in some instances: incoming.mail.yahoo.com.
I am not sure what the mrd you have before the mail is supposed to be for. You can also try removing the mrd from the incoming server line in the email settings and then try to open your email again.

Hi,

If you are not connected to the internet, you can only work offline, and for example, if you write an email it will not send until you do connect to the internet.

You can configure Outlook 2007 to work with Yahoo.

If you want to "POP" your Yahoo! Mail into your Outlook 2007 application, here's how:

1. From the Tools menu, select "Account Settings." If you do not see "Account Settings," place your cursor over the two arrows at the bottom of the list to display more choices.
2. On the Email tab, click New.
3. Check the box next to the first option, "Microsoft Exchange, POP3, IMAP, or HTTP" and click Next.
4. In the Your Name box, type your name as you'd like it to appear when you send a message.
5. In the Email Address box, enter your Yahoo! Mail address (for example, "[email protected]").
6. Check the box for "Manually configure server settings or additional server types" and click Next.
7. Check the box next to the first option "Internet E-mail" and click Next.
8. In the Server Information area, under "Account Type" select POP 3 from the pull-down menu.
9. In the Incoming mail server field, enter: pop.mail.yahoo.com.sg
10. In the Outgoing mail server (SMTP) field, enter: smtp.mail.yahoo.com.sg
11. In the Login Information area, in the User Name field, enter your Yahoo! ID (your email address without the "@yahoo.com").
12. In the Password box, enter your Yahoo! Mail password.
13. Check "Remember Password" if you don't want Outlook to prompt you for your password each time you check your mail. Handy!
14. Do not check the box labeled "Log on using Secure Password Authentication (SPA)."
15. Click on the More Settings button.
16. Click on the Outgoing Server tab and check the box next to "My outgoing server (SMTP) requires authentication."
17. Click on the Advanced tab.
18. Under "Incoming Server (POP3)", check the box next to "This server requires an encrypted connection (SSL)". The port number in the "Incoming Server (POP3)" field should automatically change from 110 to 995. If it doesn't, make sure the port number is set to 995.
19. Under "Outgoing Server (SMTP)", check the box next to "This server requires an encrypted connection (SSL)". Enter port number "465" in the "Outgoing Server (SMTP)" field.
20. If you'd like to keep a copy of your email messages on the Yahoo! Mail server, check the box next to "Leave a copy of messages on the server." If you want to delete your messages from the Yahoo! Mail server after viewing them in Outlook, don't check the box.
21. Click the OK button.
22. Click the Next button on the Email Account Wizard, then click Finished.
23. Would you like your Yahoo! Mail inbox to be your primary inbox in Outlook 7? If so, click the Tools menu and select "Account Settings." If you don't see "Account Settings," place your cursor over the two arrows at the bottom of the list to display more choices.
24. From the list, select the pop.yahoo account you've just added and click the Set as Default button.
25. Click the Close button. You're done!

Troubleshooting instructions
If you followed the above configuration steps, you should be all set. However, if you cannot send or receive mail with your email client, try the following tips.
The Yahoo! Mail SMTP server requires authentication. Make sure you have enabled SMTP authentication. To turn this setting on, follow these steps:

1. From the Tools menu, choose "Account Settings."
2. Select the "E-mail" tab.
3. Select your Yahoo! Mail account and click Change.
4. Click on the "Outgoing Server" tab.
5. Check the box next to "My Server Requires Authentication."
6. Please make sure that "Log on using" is not checked.
7. Click OK.

To control deletion of messages from the Yahoo! Mail server:

1. From the Tools menu, select "Account Settings."
2. Click on the "Email" tab.
3. Select your Yahoo! Mail account and click Change.
4. Click on the "Advanced" tab.
5. Check "Leave a copy of messages on server" if you want to save your Yahoo! Mail messages on the Yahoo! Mail server as well as on your local computer. Please note that setting your email client to remove messages from the server will cause your messages to be deleted from the server. Once the messages are deleted, we are unable to retrieve them.
6. Click OK.
7. Close Microsoft Outlook and restart.

We strongly recommend that you enable SSL for both POP and SMTP, as detailed in the above instructions. This will ensure that your Yahoo! ID, password and email messages are transmitted securely between your mail client and the Yahoo! servers. However, if you choose to not use SSL for SMTP, your email client will likely default the SMTP port to 25. If your ISP blocks port 25 or if you're unable to send email, then you will need to use port 587 when sending via Yahoo!'s SMTP server. To make this change, please follow the directions below:

1. From the "Tools" menu, select "Account Settings"
2. Select your Yahoo! POP account and click on Change.
3. Click on the "Advanced" tab.
4. Click OK and Close.

This could be a server issue. Usually if the server is malfunctioning it will lead to slowed or impeded home, and or mail issues. Do you have wireless or direct connect internet?

Troubleshooting tips
If you still can’t send Yahoo! Mail from Outlook 2007, you might be accessing the Internet through an ISP that is blocking the SMTP port. If this is the case, try using port 587 when sending email via Yahoo!’s SMTP server. To make this change:

6. In the Email Address box, type your Yahoo! Mail address (be sure to include "@yahoo.com") and click "Next."
7. Under "My incoming mail server is a…" select "POP3."
8. Type "plus.pop.mail.yahoo.com" in the Incoming Mail (POP3, IMAP, or HTTP) Server box.

10. Click "Next."
11. In the Account Name box, type your Yahoo! Mail ID (your email address without the "@yahoo.com").
12. In the Password box, type your Yahoo! Mail password.
13. If you want Outlook Express to remember your password, check the "Remember password" box.
14. Do not check the boxes labeled "Log on using Secure…"
15. Click "Next."
16. Click "Finish."
17. Select 'plus.pop.mail.yahoo.com' under 'Account,' and click 'Properties.'
18. Click the “Servers” tab.
19. Under “Outgoing Mail Server” check the box next to “My server requires authentication”
20. Click the 'Advanced' tab.
21. Under “Outgoing mail Server (SMTP)”, check the box next to “This server requires a secure connection (SSL). Enter port number “465” in the “Outgoing mail (SMTP)” field.

I found a solution posted on another site [answers.yahoo.com]which has saved me. It was posted by magnumgirl who said:

"Yahoo has been having problems lately since they have been upgrading and doing maintenance on their sites. In the meantime, you can use one of these links to access your mail, it's basic, no frills, but it works. http://us.m.yahoo.com/p/mail or: http://uk.m.yahoo.com/p/mail or; http://de.m.yahoo.com/p/mail"

Menu>Messages>>>Email>>Settings>>New Account>> Add>> Account name>> Connect using>>(Chose your ISP)>>enter email address>>select Connection type as POP3>>incoming server address for the mail you want to configure (ex yahoo= pop.mail.yahoo.com, google: pop.gmail.com) username: (yahoo or gmail login id)..>> Password( for you account)..>> outgoing server (yahoo : smtp.mail.yahoo.com or for gmail: smtp.gmail.com) please specify your login credentials again, then port number is 110 and 25. should work.
