Class A Common Stock of Easylink Services  Corporation.  The principal  business

--------------------------------------------------------------------------------
Item 2.  Identity and Background.

     (a)      AT&T Corp. ("AT&T"),
     (b)      32 Avenue of the Americas, New York, NY  10013-2412
     (c)      AT&T is a major participant in the communications industry.  The
              attached  Schedule  I is a list  of  the  executive  officers  and
              directors of AT&T which  contains the following  information  with
              respect  to each such  person:  name;  business  address;  present
              principal   occupation  or  employment  and  the  name,  principal
              business and address of any  corporation or other  organization in
              which such  employment is conducted;  and AT&T has no  controlling
              person or corporation.
     (d),(e)  During  the last five  years,  neither  AT&T  nor,  to the best of
              AT&T's  knowledge,  any  person  named  on  Schedule  I  has  been
              convicted in a criminal  proceeding  (excluding traffic violations
              or similar  misdemeanors)  or has been party to a civil proceeding
              of a judicial or administrative body of competent  jurisdiction as
              a result of which such  person  was or is  subject to a  judgment,
              decree  or  final  order  enjoining   future   violations  of,  or
              prohibiting or mandating  activities  subject to, federal or state
              securities  laws or finding  any  violation  with  respect to such
              laws.
     (f)      a New York corporation
--------------------------------------------------------------------------------
Item 3.  Source and Amount of Funds or Other Consideration.

In  connection  with  the   restructuring   of   approximately   $35,000,000  of
indebtedness  (the  "Indebtedness")  owed by the Issuer to AT&T,  including  the
retirement of portions of the Indebtedness and an extension of the maturity date
with respect to the remaining  indebtedness,  the Issuer transferred  14,239,798
shares of its Class A Common Stock to AT&T and gave AT&T immediately exercisable
warrants  to purchase an  additional  10,000,000  shares at a price of $0.61 per
share. The Indebtedness was created by the Issuer's default under the terms of a
promissory  note  made by the  Issuer  in  favor of AT&T.  The  promissory  note
evidenced  the  Issuer's  obligation  to pay AT&T for certain  services  under a
Transition  Services  Agreement by and between the Issuer and AT&T,  dated as of
January 31, 2001.
--------------------------------------------------------------------------------
Item 4.  Purpose of Transaction.

As a result of the debt  restructuring  of the Issuer  (more fully  described in
Item 3,  above),  AT&T  acquired the Class A Common Stock that is the subject of
this  Schedule  (the  "Shares").  AT&T  intends to treat the Common Stock of the
Issuer as a passive  investment  and will realize a gain or loss, if any, on the
sale of the Shares if sold.
--------------------------------------------------------------------------------



Item 5.  Interest in Securities of the Issuer.

     (a)      AT&T is the beneficial  owner of the Shares.  The Shares represent
              approximately  14.7% of the total  number of shares of the Class A
              Common  Stock  of the  Issuer  as of  November  30,  2001.  To the
              knowledge of the Reporting  Person,  none of the persons listed on
              Schedule I hereto  beneficially owns any shares of Common Stock or
              other securities of the Issuer.
     (b)      AT&T maintains the power to vote or to direct the voting of, and
              the power to dispose of, or to direct the disposition of, the
              Shares.
     (c)      Except as otherwise set forth herein, neither the Reporting Person
              nor, to the knowledge of the Reporting Person,  any of the persons
              listed on  Schedule  I, has  executed  transactions  in the Common
              Stock during the past 60 days.
     (d)      Except for the Reporting  Person,  there is no person that has the
              right to receive or the power to direct the  receipt of  dividends
              from, or the proceeds from the sale of, the Shares.
--------------------------------------------------------------------------------
Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.

AT&T and the Issuer are parties to a Registration Rights Agreement,  dated as of
