Hi, I am trying to attach a file in the Outlook mail system using C# UWP, but it's not working. It works fine in the old Mail app. Could you please help?
Code:
EmailMessage emailMessage = new EmailMessage();
StorageFile attachmentFile = await storageFolder.GetFileAsync("TXT_Files\\Purchase Status.txt");
if (attachmentFile != null)
{
var stream = Windows.Storage.Streams.RandomAccessStreamReference.CreateFromFile(attachmentFile);
var attachment = new Windows.ApplicationModel.Email.EmailAttachment(attachmentFile.Name, stream);
emailMessage.Attachments.Add(attachment);
}
await EmailManager.ShowComposeNewEmailAsync(emailMessage);
Hi @Jay ,
This is a known issue.
If you want to solve this problem in UWP, I think you may need to use Desktop Bridge to launch desktop application from UWP, and call System.Net.Mail to send emails with attachment.
This requires UWP to run under full trust permissions, in simple terms, UWP will leave the sandbox. You need to consider the pros and cons.
Thank you.
Okay Thanks @Junjie Zhu - MSFT
It seems that the attachments “... will appear only in the Mail app. If users have any other mail program configured as their default mail program, the compose window will appear without the attachment. This is a known issue”:
To work around the momentary known issue, maybe you can insert the Purchase Status to the body of email.
Hi @Viorel
Thank you for your kind reply. However, Outlook is also a mail app, and now, when I open the old mail app, it automatically redirects to the latest Microsoft Outlook Mail app. I thought it would work in the latest Outlook Mail app, but it doesn’t.

Yes, but our app is an invoicing app, and we need to attach the invoice PDF to the email. Most of our users have complained that they cannot attach any PDFs in the Outlook mail app, so we need a solution or an alternative for this issue.
