I am using java code to compose and send e-mail messages to MS Outlook 365 accounts. The message is composed as following:
- plain text part;
- html part containing only table;
- plain text part;
- File attachment.
I expect that outlook displays part 1-3 as message body and the last part as attachment. Instead it displays only first part as message itself and puts the rest parts as separate attachments. I have played with different headers, but result is the same. Is it some feature of MS stack (exchange, outlook, etc.) or I did something wrong?
The raw message is here

As a result I see only "Content before table" line, two attachments like "ATT01.html" and "ATT02.txt" and my original attachment "report.xls".
I have found one related topic at some forum saying that this problem should not appear since Outlook 2010 or so, but I can see it in the latest version both in desktop app and the web application. The workaround solution to put everything in html part requires more work, because text parts are generated by other components.
