Unable to add an email to Yahoo! profile

Earlier I could add/delete an email to Yahoo! profile. Now I get error as follows:

Quote:
You’ve exceeded the maximum number of email addresses that you may add to your account. You may delete one of your existing email addresses, then add another.
Unquote:

I deleted all emails except one i.e. default but I am unable to add an email.

Any suggestions!

It may have been due to lag, sending that information the confirms that your contacts has been deleted try a little later

Whilst I have never used Yahoo, I find it hard to believe avast could have any possible involvement here. Since the error is generated by Yahoo the control is that of Yahoos.

Your error message if you read it again isn’t about emails but email addresses oneaddr (at) yahoo (dot) com, twoaddr (at) yahoo (dot) com, threeaddr (at) yahoo (dot) com. So in your profile you might be allowed only one email address for that account.

You could have hundreds of emails for that address in your account but not different email addresses that you can send and receive email for that account/profile.

Google is your friend, Yahoo You’ve exceeded the maximum number of email addresses that you may add to your account.

Which returns many hits, this is the first and probably most relevant, http://answers.yahoo.com/question/index?qid=20080830105506AAezvLJ.
