Hi @itforsenior, sorry for the delay in response. How is your Webmail now? Were you able to get help in this regards since posting? Check out this link with more info on Webmail settings if it helps. If the issue persist then you will need to raise this with Tech Support on 131344 (open 24x7) to investigate further.
Thank you for response. No other help forthcoming, the link does not cover this issue. It looks as if mail older than 7 days is deleted, I can accept that, you cannot carry unlimited amounts.
