Ipad imap account deleting mail from server
I've had my ipad for a few years and never had this problem until this week. I use my ipad and a laptop for my business and mail I deleted on my ipad has started disappearing from the server, so I can't download it on my laptop.
I've set up the imap accounts again but same thing happens. I've contacted my isp and they say all their settings are correct.
Anyone know what might be happening? Anything I can do besides not deleting on my ipad?
