No. Not working at all.

Btw, here is the answer -

Hello ******,

Thank you for contacting Yahoo Customer Care.

I understand that you are want to remove email alias on your Yahoo account "************@ymail.com". I am happy to assist you with it.

Unfortunately, what you're looking for "Remove email alias" isn't possible in the current version of the product. I can see how that'd be useful, though.

You should post your suggestion to add that function on our feedback forum. Our product teams review the posts and look for ideas to include in future releases.

Regards,

Alexandra
Yahoo Customer Care
