Send Email: "Add Attachments" Option Not Working (Grayed Out)

Dear ERPNext team,

When sending an email from within a document, e.g. on submission of a quotation, the “Add Attachments” Option is grayed out and not working, which means I cannot upload any additional files at this stage:

I also could not find any relevant setting in setup, so I was wondering if the inactive upload option might be a bug.

Best regards,

Stefan

You need to attach the files into document first. Then those document should be available for sending in the email window.

You are right, and this this is how I normally deal with attachments. However, in this case I had already submitted the document (but not sent the notification email yet), when I realized I had forgotten to attach an important document.

What is considered best practice in this case? Cancel → Amend the document, attach the file and submit it again? Or is there another way to do it?

Best regards,

Stefan
