Do you know why I get the syntax error Msg 102, Level 15 while using SQL Server 2005?

I am developing an Access application using Access 2003 with an ADP type file.

Do you now why the following statement causes a syntax error using SQL Server 2005?
The syntax error is as follows:

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near 'A'

delete
from dbo.tblGetDocumentAttributes A
where exists (select 1 from dbo.tblGetDocumentAttributes B
                      where B.Account = A.Account
                      and B.DocumentDate = A.DocumentDate                    
                      and B.MailID < A.MailID)
----------------------------------------------------------------------------

     MailID   Account   DocumentDate                     ScanDate    Amount.
 1   A34R   45677      2010-08-31 00:00:00.000
 2   B78E    45677      2010-09-30 00:00:00.000
 3   R546    45677      2011-01-31 00:00:00.000
 4   G555    45677      2011-01-31 00:00:00.000
 5   C645    86453      2010-08-31 00:00:00.000
 6   E567    86453      2010-09-30 00:00:00.000
 7   R546    86543      2011-01-31 00:00:00.000
 8   R555    86543      2011-02-28 00:00:00.000


My goal was to delete any records from this table in which
any particular account has multiple records with the same documentdate and in these instances just keep the record with the higher MailID (type nvarchar) ?

So in the example above, the 4th record would be deleted because it has the same
account plus documentdate as record 3 but record 4 has the lower ranking MailID.
