Microsoft Outlook web mail not recognizing mailto calls

[Hugh Senior]

Mark:

Settings: Internet Properties: Programs Tab: E-Mail popup menu... select
Microsoft Outlook.

To verify, get queryRegistry("HKEY_CLASSES_ROOT\mailto\shell\open\command\")
will return the key (i.e. string of data) containing the path to the default
mailto: program.

/H

The following returns a system error for a person here who is using
Microsoft Outlook web mail.  This particular user also gets errors when
clicking mailto HREFs in a web page.

  put "mailto:john at example.com" into tMessage
  revGoURL tMessage
  if the result is not empty then
    <error checking>
  end if

My error checking never kicks in, so the result is empty.  Any ideas on how
to determine in advance if a mailto is going to work for a given user?

Thanks

Mark
