Is there some new setting or policy with the switch to the POP server that messages in your Inbox are automatically deleted after X number of days?  I have a mail client at home downloading them, but it is set to leave the copies on the server.  It does.  I can log on through the internet and see that they are still there, but now they are continually gone after a a week or two.  I don't see any setting online to address this or any comments as to a change having taken place.  Please help.

Hi. I realize that you need this issue resolved immediately. I have moved your post here in this forum.

No, there's no setting or policy with the switch to using the POP3 settings. I suggest that you first re-configure your account in your e-mail client. If the problem persists, contact your e-mail client's support team as it may have settings that do this behavior.
