Sky changed email suppler app 7 months ago since then sky mail has never worked as it should. I have contacted customer services but sky mail still performs badly. The problem is it does not retain mail in the inbox sorry it does retain some, to give you an idea I have only 12 emails in my in box. Iam using win 7 and thunderbird 24 in TB I have enabled to keep messages on server. Any help would be welcome as Sky do seem to be interested
