If skype deletes messages from as far back as February from an account is there anyway to recover these or are they gone for ever? The reason for this question is that a friend is involved in a court case and the messages that cannot be accessed any more would help her cause.
Apparently the maximum is 30 days unless required or permitted by law. Contact Skype to confirm for your area.
