I am already successfully creating the email with this command: /usr/bin/open -b com.microsoft.outlook 'mailto:[email protected]?subject=reports&body=Please find attached reports' but I cannot figure out how to pass an argument to attach a file

Answer 1

mailto protocols does not support attachments. You can only do to (the default mailto parameter), cc, bcc, subject, body. No attachments or HTML body.

Answer 2

The mailto protocol opens a client's e-mail system and begins a new email message. The optional parameters can be one of the following strings:

• subject - Text to appear in the subject line of the message.
• body - Text to appear in the body of the message.
• CC - Addresses to be included in the "cc" (carbon copy) section of the message.
• BCC - Addresses to be included in the "bcc" (blind carbon copy) section of the message.

There is no way to specify any attachments.
