New Post: unable to search inbox

My code snippet is as below.

Private imap As ImapClient
Private _messages As List(Of Message)


Private Function Logintoserver() As Boolean

    imap = New ImapClient(ServerName, True, False)
    imap.Connect()
    Return imap.Login(UserId, Password)

End Function

If Logintoserver() Then

        MsgBox("sucess")
        Dim myinbox As Folder = imap.Folders.Inbox
        _messages = myinbox.Search("ALL", True)

    Else
        MsgBox("failed")
    End If

Search is giving error.
Error 1 'Public Function Search(path As String, makeProcess As Boolean) As ImapX.Collections.MessageCollection' is obsolete: 'This Search overload is obsolete, please use another instead'.

Please help.
