How to restore deleted emails?

Need to restore emails that Outlook deleted from the mail server

• I wanted to use POP mail for my Yahoo mail account. So I went to the Yahoo mail settings and enabled POP feature. I installed Microsoft Outlook 2007 and added the settings for my Yahoo mail account. Then I performed a sync. I successfully received all the emails from Yahoo account into my pc. But when I logged into my Yahoo mail online, to my horror all the mails were deleted. It seems someone in Microsoft for some reason decided to keep the default setting unchecked for "Leave copy of messages on the server". This has been a very old account and I need to have all the mails also present on the mail server so I can access it anytime and future purposes. Is there anyway I can restore these emails on the server again? Any ideas how I can get it back to the way it was? I have been googling this for quite sometime now but I'm not able to find it. Any helpful suggestions are welcome. Thanks.

• Answer:

  As TFM has pointed out, this is the default setting of POP3. For us old school guys, this is what we expect. Back in the day, keeping emails on your PC and your mail server was expensive. We had rinky dinky 800 MB harddrives and even less room on our mail servers. That was the reality when I first started using POP. And that was what POP was originally designed for. If all your emails are still in Outlook, there is an easy remedy. Just email all those messages back to yourself, making sure to leave a copy on the server. This reminds me of the stories on The Old New Thing. One of those situations where Microsoft gets blamed whether or not it's actually their fault. They might of did this to stay compliant. But that of course has its consequences. I remember when XP first came out and finally got rid of the accursed DOS kernel. People riotted!!
