Editing EML files

Aspose.Email Product Family

We have an API where we save eml files to Group Mailbox (O365 unified group).
We need to add extra header information to the eml file before saving these files to Group mail.
Can we use Aspose.Email for this purpose?

Thanks

We have an API where we import EML files from User Exchange MailBox to Group MailBox
These ELM files are of the Stream type.

For outgping mail we would like to add value in the EML header “X-Msg2Mime-Client-Submit-Time”. Before we save the elm file to Group Mailbox

Yes, they can add extra header in MailMessages before them will be appended by EWS client to O365 mailbox. You may use IMAP client.

  MailMessage message = new MailMessage(
                        user.EMail,
                        user.EMail,
                        "Subject " + Guid.NewGuid().ToString(),
                        "body");
                    message.Headers.Set("NewHeader", "HeaderValue");
                    string uri1 = client.AppendMessage(mbInfo.InboxUri, message);

Thanks, I can see my outgoing EML missing “PR_CLIENT_SUBMIT_TIME” and because of that, mails getting wrong datetime.

Is there any way to add “PR_CLIENT_SUBMIT_TIME” to header?

MailMessage mails = MailMessage.Load(mailStream);

Hi

I’m using load from Stream for getting EML-stream. In this case I can’t see the SetProperty method for mailmessage.

MailMessage mails = MailMessage.Load(emlStream);

These are MapiMessage properties and not MailMessage. Can you please consider using MapiMessage instead of MailMessage.
