Mail not being received after adding a ReplyRecipient - outlook

Question

Using Outlook for Microsoft Office 365 32 bit and Delphi XE8
I am evaluation Redemption.dll as Windows 11 has blocked my application from accessing Outlook.
I have Outlook configure with multiple profiles and stores
I can open the profiles find the store/account and can send/receive.
In one combination I do not receive the email.
The issue is with
Mail.ReplyRecipients.Add('xxx#gmail.com');
if I comment this line out I receive the email
In the sent folder I can dblclick and by clicking reply I see the Reply Address but in the inbox (of the recipient) I get nothing. I scanned all Outlook items to no avail.
In the reverse direction I do receive the email.
I intend ti purchase the product on completion of my evaluation. But this feature is important
procedure TForm61._Send(Profile, Sender, _To, _CC, _BCC, Subject, Body: String;
ReadReceiptRequested: Boolean; _Attachments: TArray<String>);
var
FolderFound: Boolean;
c, j, Count, k: Integer;
Session: IRDOSession;
Store: IRDOStore;
Drafts: IRDOFolder;
Recip: IRDORecipient;
MAil: IRDOMail;
IPMRoot: IRDOFolder;
ReplyRecip: IRDORecipient;
_name: String;
begin
Session:=CoRDOSession.Create;
Session.Logon(Profile,'', False, True,EmptyParam,EmptyParam);
Drafts:=Session.GetFolderFromPath('\\'+Sender+'\Inbox');
Mail:= Drafts.Items.Add(olMailItem);
Recip := Mail.Recipients.Add(_To);
Recip.type_:= olTo;
if not _CC.IsEmpty then
begin
Recip := Mail.Recipients.Add(_CC);
Recip.type_:= olCC;
end;
if not _BCC.IsEmpty then
begin
Recip := Mail.Recipients.Add(_BCC);
Recip.type_:= olBCC;
end;
// Recip.Resolve(EmptyParam, EmptyParam);
// ReplyRecip:=Mail.ReplyRecipients.Add('xxx#gmail.com');
Mail.ReplyRecipients.Add('xxx#gmail.com');
// ReplyRecip.Resolve(EmptyParam, EmptyParam);
for j:=0 to Length(_Attachments)- 1 do
Mail.Attachments.Add(_Attachments[j], EmptyParam, EmptyParam, EmptyParam);
Mail.Subject:=Subject;
Mail.ReadReceiptRequested:=ReadReceiptRequested;
Mail.HTMLBody:=Body;
if SignatureIndex>-1 then
begin
Signature:=Session.Signatures.Item(SignatureIndex+1); //noy zero-based
Signature.ApplyTo(Mail, False);
end;
Mail.OriginatorDeliveryReportRequested:=True;
Mail.Save;
