Help with TCOM syntax

I understand
package require tcom
set UserInfo [::tcom::ref getobject "WinNT://$Domain/$User"]
$UserInfo name
$UserInfo fullname
$UserInfo Accountdisabled
All those operate as expected.

What is the syntax to get other properties of the user. None of the
tricks I use - looking in AD or ldap explorer seem to yield anything.
I am looking speciffically for the email account = mail in LDAP;
E-mail in AD. Tried all the case permutations.

All respond with
object does not implement method or property

::tcom::info interface $UserInfo
returns
cannot get type information

I know I am missing something obvious - I have been able to operate
Excel worksheets and parse out existing properties.

Other ways to get same sort of info?
