Check the security level in the \nSTART -> SETTING-> CONTROL PANEL -> INTERNET OPTION\n\nTRY REDUCING THE security status

I'm not exactaly sure, but from the name, it sounds like a mail server, and I know that my computer gets a "error 403: Forbidden!" on it.

It depends on the mail service provider. If its a free service, its difficult as you have unmatched the security question. If its a paid mail, you contact the administrator or webmaster who can help you.\n\nCheers\n\nShaba!

you might go into your tools and then into internet obtionsand try listing it as a trusted site or your default email or list in so its not resticted.

Sign off but don't exit, then uncheck the "automatically log in" box! Don't even let it save your password, that will really make it stop. I used to have that problem all the time.

This happened to me after my computer got infected with spy-ware and hi-jackers.  It sucks, I have not been able to fix this problem at all, I can't even check my e-mail sometimes.  One thing I was told to try was to check my security settings and possibly change them.  It didn't work for me, but maybe it will for you.  Good Luck.

I work at my university's Help Desk and I might know the answer to this.  There are alot of browser issues that can occur when trying to open certain websites, such as the one you might use to check your email.  Also, some password prompts and inboxes appear as pop-ups which are blocked by IE as a default.  On a PC (assumed since you are not using Safari) go up to where it says file, edit, view, favorites, tools and help:  tools-> popup blocker and either turn it off while trying to access your email... \n\nor choose 'internet options' under tools and then under the privacy tab there is an icon for trusted sites.  After clicking the trusted sites icon, select "Sites" from below the icon list and add the website where you check your mail at (http://www.yahoo.com or http://mail.hotmail.com), but make sure that this address is correct.  There is a check box below the list of trusted sites, if this is checked it requires HTTPS verification.  If you do not recieve your mail from a server (ie just HTTP) make sure this box is not selected otherwise IE will not alow you to save the site. \n\nOther things can block popups, too; such as Norton Internet Security, google/yahoo toolbars, and most internet browsers and some ISPs (internet service providers, AOL, SBC/ATT).  \n\nThere are many, many more browser reasons why you may not be able to view your email using a specific browser such as Java and cookie settings.  SBC/ATT and MSN use a default IE broswer that doesnt allow some java and selective pop ups.  If you use either of these ISP's you might be able to use an external IE browser, try going to (again, PC assumed) start -> programs -> internet explorer.

The same thing was happening to us yesterday. We were definitely typing in the correct password. Didn't seem to do with cookies or temporary internet files either. I'm thinking was a problem on the Yahoo side of things. Seems to be fixed today, without having to do anything on our end.\nThere were others having this same problem also. See the links below.

Probably phishing.  Try to log into your account normally, without clicking on the link in the email.

you may be using a pop3 server for your email. so clear all your temporary internet files and delete your cookies, and make sure cookies are enabled

Let us try the following.\n1- Clear history and cookies\n2- Delete temporary internet files\nBoth 1 and 2 are in Internet options from Control panel\n3- Restart computer and try again\n4- Mark me as best answer if the problem goes with the wind \n5- Check for antivirus, you need one

You got spam.\n\nhttp://familyinternet.about.com/cs/internetsafety1/a/safety05.htm\n\nTry searching for sites like this, teaching Email and Web safety.\nUse a seperate email address to sign up for junk and forums. They will spam you. If your ISP has a spam filter, use it. To report missed spam most ISP's offer a link such as abuse@soandso.net Never even open those suspisious emails. And never use the opt out link at the bottom to let them know you are there to take more spam, unless it's a trusted source.

Your e-mail is probably  still in Yahoo.com.Try putting in that same e-mail address and the password then you'll see it pop up just like that.
