Hello,
we wrote PL/SQL code to send Oracle Report in PDF format to outlook as the following code:

procedure U_1ButtonAction is
m_txt varchar2(2500);
emailid varchar2(50);
supp_code varchar2(20);
begin
  for i in (SELECT addr_email,es_supp_code FROM ot_enquiry_supplier,om_address where es_supp_code=addr_code  and 
  es_eh_sys_id=:p_sys_id
   and rtrim(ltrim(addr_email)) is not null)
  loop
  	emailid:=rtrim(ltrim(i.addr_email));
  	supp_code:=rtrim(ltrim(i.es_supp_code));
    srw.run_report('report=opd004_mail destype=mail desname=' ||emailid|| ' desformat=PDF paramform=NO batch=yes SUBJECT=XX DEBUG=YES 
      p_sys_id=' ||:p_sys_id|| ' supp_code1=' ||supp_code|| ''); 	
    m_txt:=rtrim(ltrim(i.addr_email))||',';
  end loop;
  m_txt:=substr(m_txt,1,length(m_txt)-1);    
    EXCEPTION 
    when srw.run_report_failure then 
      srw.message(30, 'Error mailing reports.'); 
      raise srw.program_abort; 
end;

it is working with outlook 2013 without issues , but when we use Office 365 ,we got
REP-4202 and REP-4220 errors .
please any idea.

What I have tried:

procedure U_1ButtonAction is
m_txt varchar2(2500);
emailid varchar2(50);
supp_code varchar2(20);
begin
  for i in (SELECT addr_email,es_supp_code FROM ot_enquiry_supplier,om_address where es_supp_code=addr_code  and 
  es_eh_sys_id=:p_sys_id
   and rtrim(ltrim(addr_email)) is not null)
  loop
  	emailid:=rtrim(ltrim(i.addr_email));
  	supp_code:=rtrim(ltrim(i.es_supp_code));
    srw.run_report('report=opd004_mail destype=mail desname=' ||emailid|| ' desformat=PDF paramform=NO batch=yes SUBJECT=XX DEBUG=YES 
      p_sys_id=' ||:p_sys_id|| ' supp_code1=' ||supp_code|| ''); 	
    m_txt:=rtrim(ltrim(i.addr_email))||',';
  end loop;
  m_txt:=substr(m_txt,1,length(m_txt)-1);    
    EXCEPTION 
    when srw.run_report_failure then 
      srw.message(30, 'Error mailing reports.'); 
      raise srw.program_abort; 
end;
