As per the subject line I have three talktalk email addresses and one of them continually redownloads deleted and read emails to my iPhone and iPad. This uses the data on my phone plan very quickly. Even if I just mark them as "Read" the phone or iPad then download them again as unread.
The same address also is downloading multiple copies to outlook on my PC.
Very confusing as it is only happening to one of my talktalk addresses?
