Thanks, Sergey. I think, something got misconfigured when I choose Opera to be my default mail client. I then changed it back to Outlook and instructed Opera to use Outlook as a mail client, but perhaps it was not enough. I am just wondering where should I look and how can I fix the problem, because it would be convenient to just press a button while reading topic in Help.
