macbook air - mail problem

my macbook air deletes folder contents. It stared by deleting sent folder, now it has deleted the inbox !

I've checked all the settings - all are "never delete".

Where next ?

We need more information. Your Mac can not arbitrarily delete folders without something else going on. To start with.... who is your email provider (ISP)? Also tell us which MBA you have and version of OS X it's running?

macbook air mail problem

Hi, the laptop is not with me at the moment, so I can't tell the OS (?Lion, I think)

It's not deleting folders, it's deleting the contents of the folders.
ISP is BTinternet.

As far as I can tell, on a two week cycle, it's deleting all Emails except the current day.
Sometimes it's the sent box, the latest is the Inbox.
The problem is only recent - 4 months OK, last 2 or 3 months..... KO

There are two accounts on the laptop. One has this problem, the other not !
I can't find any difference between the settings of the two accounts.
I've gone into settings and the delete instructions are "never delete", including on the server.
Going onto the webmail shows that the mails have gone off the server.

Next thing is to ring BT helpline !!

You're doing everything correct as far as I can tell. I would certainly give BT a call and find out if something else is going on.

Not saying yours is the same issue, but a friend in the UK had a similar problem about a month ago, re disappearing mail from server. Turned out to be BT issue. Will just add that she was in the throws of ditching BT and moving to another ISP.

Not to be "that guy" (okay, yes I'm being "that guy"), but it's "throes."

Homonyms trip everyone up sometimes, myself included. Just thought you'd want to know for future reference.

mail problem

The only problem re phoning BT is that they are not very good with Apple as they clearly prefer PCs.

That's a good reason to switch ISPs if ever I heard one.

Bottom line: barring some technical malfeasance on the provider's part, this sound like a classic case of POP mail being used like IMAP with the predictable end result.

The "real" solution to the problem is this: if you're going to stick with a POP-based account, pick a single device to manage your mail and DON'T use other devices.

Otherwise, switch (or forward your POP mail) to an IMAP-based account (iCloud, Yahoo, Google etc) and the problem will resolve itself. IMAP means you can manage mail seamlessly on multiple devices.
