Hello! Thank you for your question. I am a licensed computer / tablet professional with over ten years of experience, and I will be assisting you today.I'm sorry about the issue. What email do you use, such as Hotmail, Yahoo, Gmail, AOL, etc.?Is there any error or message?Was it working previously on the iPad?Do you mean you cannot empty the trash mail box on the iPad? Only if you delete trash mail on your HP computer, then it would get deleted on your iPad also?
Have you rebooted the iPad?
Have you tried to delete the email account from the ipad, then re-add it?Please reply at the box below. Thank you,
