If you're using Outlook as a default email client to send and received emails and you get this message "The server responded: 452", chances are your Webmail is full. To resolve this issue;
- You need to log in to your Webmail account and delete items to free up usage space (make sure you also delete items in the Deleted Items" folder too)
- Alternatively you can set your Outlook to remove messages from your Webmail (by default it is set to do so) but if it's not you can go to Tools->Options->Mail Setup->Email Accounts-> click on the active email then click "change" ->More Settings-> Advanced tab->Delivery field UNCHECK "Leave a copy of message on the server"
