You will need
  • - computer with Internet access;
  • - the account "Vkontakte".
Go to a social network "Vkontakte", entering your username and password on the main page ( Check out the conversations by going to "Messages" in the menu column on the left.
If you are interested in remote correspondence with a certain person, you can do the following: contact him directly and ask them to copy and send you all your messages. This option is the most simple, because the interlocutor is hardly touched their messages (to delete an entire conversation from network "Vkontakte" does not allow technically, to remove the entire history one item quite troublesome).
If you are interested in messages from different people, then the above method won't work. Go to your page, at the bottom you will see the line "on the website, help, blog, rules, advertising, developers, jobs". Select "help".
Enter in the box at the top of the page your question is for people working in technical support (under "Here You can let us know about any problem with Vkontakte"). Write that accidentally deleted important message and ask them to restore at least part of them. If such a possibility exists, that to you necessarily will help.
Check your mail, because there may come the answer to your question. Remember that support gets a day, thousands of messages, so don't expect a reply in five minutes.
