I have tried opening the link given in the subject title link but it won`t let me.
The problem I am having is when sending an TT webmail emails with an attachment I get the sending notification but it continues for a very long time normally ending with a "Ecountered a technical error please retry" I have resent the emails several times with the same result, and never getting the "Back to Inbox" button up.
When checking with the recipient of the email I find that that the person has received the email as many times as I have sent it.
The only way to check if it has been sent from my account is to look in the Sent box. This has not happen with emails with no attachments.
