The email being deleted on your iPhone should synchronise to the TalkTalk mailbox so that the same action is carried out online and the message is moved to the Trash folder. But if the iPhone does not synchronise then the message goes into a local Bin folder only. The mailbox will synchronise in due course and the messages still in the online Inbox will be delivered to the local Inbox.
At what point does loading of the webmail page stop?
