Emails being deleted from Bin
After reading an email in my inbox, I delete it and it goes to the Bin. I have noticed that I can't retrieve any older emails from the Bin when needed, to view previous conversations, quotations etc. I clean up my email once a year, so there should be hundreds or thousands of emails in the Bin. From last years business I have 17 emails in the Bin. Does anybody have any idea where these emails are going and can they be retrieved ?
