How to interpretate email address

[Guest]

Mary Painter works for a company "marycompany" and access emails via their
own MS Exchange server, as usual.

Almost every time when Mary receives an external email and when she opens it
Outlook displays (as usual):
From: ...whoever
To: Painter, Mary
cc: ....
Subjec: whatever.,,
And then the Body message.

However, one day Mary received an email from another company "xyzCompany"
but her normal email address (Painter, Mary) was not displayed under the
"To:"

The name under "To" is generic - it read say "ABC, Accounts" (yes, there is
a comma.

I understand a little about putting together a few email-addresses and place
them under a group name (so that I can send the same email to a number of
persons). But I do a search in the Outlook "Global address List" at
"maryCompany" side but couldn't find anything to look like "ABC, Accounts".
Do I miss anything? I was about to conclude "ABC, Accounts" must be a
distribution list defined in xxxCompany rather than in "maryCompany". Can you
confirm me?

But is there a good way to tell what the distribution list is defined?

What is displayed in the To field is determined by the sender. Apparently
most of Mary's correspondents have a display name of "Painter, Mary" for the
contact record representing her in their mail clients and that's what they
use. This other person has a display name of "ABC, Accounts" for the
contact record containing Mary's mail address. A sender can have a display
name of "Wonder Woman" for a particular contact and that's what the
recipient will see. Ther's nothing unusual about what Mary sees.

Thanks for clear explanation.

When the Outlook email is opened, if Mary right clicks on "ABC, Accounts"
and select properties, it reads:
Display Name: ABC, Accounts
Email address: (e-mail address removed)
Email-type: SMTP

Is there any relation between Mary Painter email and
(e-mail address removed)?

This looks to me like whomever sent the message is using mailing list
software to send it. They have a list, "abc-accounts" that contain a number
of addresses, including Mary's. They sent their message to that list
processor, which in turn sent out the message to the people in the list.
That processor included (e-mail address removed) in the "To" field, but
used the Bcc field to include the real address, Mary's. The contents of the
To field really has no bearing on to whom messages are delivered. It can
contain anything at all. The REAL delivery information is handled by the
SMTP envelope the mail routers use. This of it as the post office
delivering a piece of real mail. The envelope contains the real address.
The letter inside can say "Dear Mickey Mouse" without affecting the real
addressee.
