Yahoo! Archives messages under the profiles section of the install directory. If you have cleared the archives, those messages are deleted, although there are still remnants of user names throughout your system via logs, and registry entries.

You probably deleted them the first time but the screen didn't refresh.  That error means they are not there anymore.

it depends, if you have activated your message archiving and if you already had a previous conversation with any of those contacts of yours then yahoo messenger will save those offline messages, the reason for that is yahoo creates a folder for each of your contacts that you had a conversation with, and once it is able to find a folder with that contact's id then it'll save those offline messages.

In older versions of Yahoo Messenger, there used to be a way to look at your offlin messages. But in newer version of it, you can not look at them as such. If there are any offline messages, they would be displayed as soon as you log in. When you close the window displaying these messages, the messages get deleted, and can not be seen again.\nSo, the only reason why you cant find any offline messages is cuz you dont have any!

Usually the only things retained on the Internet are those things posted to a bulletin board, website or USENET.  You can search for that at Google Groups.  If it's chat like with AIM or Yahoo Messenger and you don't have it set to log your chat, then no -- it's gone forever.  As for your emails, that's pretty much the same thing.  ISPs will keep copies of your emails for a while, but after a certain point, they'll just purge it.  If it's something you want to hang on to, you should consider saving it to disk or printing it out.

you need your own computer.  if you have this already, then setup password protect on your account.  then lock your computer when you're not using it.  your messenger conversations are saved on your computer, you can delete the history of the conversation, not through internet options though.

off line messages will be displayed as soon as you log in. \nif you close the offline message window, then those messages will be deleted and can never ever be recovered.\n\nlook in to your settings and see if you have disabled offline message notification.

No they are not deleted because that happened to me and I thought I lost them, just look and try to find the bookmarks, click on one of them and they all show again, I think is the program is not that you have any virus, anyway they are there somewhere..☺

The same thing happened to me. They just stopped showing up the other day. I have had the same question posted ever since. From the looks of it, there are several other people with the same problem. Do you know of a way to directly contact Yahoo!?

I have had this problem before, if you are sure its not an important file and its probably not if its on your desktop, you have probably allready deleted them but your system has not picked up on them being deleted yet, this happens to me sometimes after my computer has been on for a while, you just need to refresh your screen, or if that does not work try just to reboot that should take care of it.

if you permanently deleted them then they are gone for good.  you could ask the people again for them, but besides that you won't have much luck.  that's why you should allways be careful when deleteing things, sometimes they cannot be restored

Unless you regularly archive your e-mail, once deleted, they are gone. Your trash folder should catch e-mails you have deleted unless otherwise specified. Also, you may still be able to retrieve files from your server if you have previously configured your e-mail client to keep messages on the server.
