Problem to delete an attachment in an email when in Rich Text Format. the TAttachment.Delete method works well in HTML and Plain Text format, but gives an error in RTF.

The following code works well when deleting the first attachment in an Outlook MailItem, however only when the format is HTML or Plain. In RichText it fails with the message:
"xxxxx_class_error: the add-in has fired an exception. The operation failed."

The error occures during the a.Delete call.
Any suggestion what goes wrong?

Thanks



var
IDsp: IDispatch;
Mail: outlook2010.MailItem;
attachments: outlook2010.attachments;
a: outlook2010.Attachment;
begin
IDsp := OutlookApp.ActiveInspector.CurrentItem;
if Assigned(IDsp) then begin
IDsp.QueryInterface(IID__MailItem, Mail);
if Assigned(Mail) then begin
attachments := Mail.Attachments;
if attachments.Count > 0 then begin
a := attachments.Item(1);
a.Delete;
end;
end;
end;
end;

Hello Ralf,

Does this occur on an IMAP folder, PST, Exchange?

Hello Andrei,
This is in an Outlook Inspector (Outlook 2010) in an opened Email (for instance a new created email). I use the above procedure to delete attachments in a new created email. Later I want to use that for emails arriving to the Inbox.
Hope this helps,
Best Regards,
Ralf

Ralf,

Thank you. Outlook receives and stores emails in different store types. My question is about the store type used in your case. If this is a corporate email, then most probably it is Exchange. If you use Gmail or Hotmail, then it may be IMAP folder.

I also believe the other issue you describe in a separate topic may relate to the store type used.

Ralf,

Please create a new email in Outlook, attach an email producing the issue, and send the email to the support email address; please find it in {Add-in Express installation folder}\readme.txt. Also, make sure your email contains a link to this topic.

What build of Outlook 2010 are you using?

Hello Ralf,

Thank you for sending me that email. The code above works correctly for me on that item. I suggest that you install SP2 and subsequent updates on Office 2010.

Hello Andrei,
thanks for the feedback. I just figured out, that the email needs to be saved, before being able to use the delete method for the mail item's attachments. Strange that this is only the case when the email is in RTF format!
Anyhow, I hope this is a stable solution.

Thanks,
Ralf
