FlexConfirmMail v22.7.2

Improvements

• Modified to not create needless registry key
  • FlexConfirmMail supports Outlook 2016+, so we need add registry keys only for Software\Microsoft\Office\16.0.
    Also, Office skips the internal version "13", so there is no Office version corresponding to Software\Microsoft\Office\13.0.

Bug fixes

• Fixed a bug that inline reply may break an original mail.
  • The addin did MailItem.Save on clicking reply, but MailItem.Save may fail and did unexpected behavior when a mail item is an inline reply mail as its specification. So fixed to not use MailItem.Save.
