Why on Earth would you do away with "Old Mail"? I've used AOL for many years and now I'm starting to find that is "Unusable" because of your recent changes. Sad, you're going backwards not getting better like you should. Please restore this or you are going to lose many more customers in my opinion.
Could you please message us on Twitter at @AOLSupportHelp or on Facebook at AOL Customer Care? We'd like to look more into the issue you're experiencing. In case you do not have a social media account, we are also available at: https://help.aol.com/contact/
Looking forward to your reply!
