message source line breaks
In the new View Message Source, the text is not formatted correctly. Line breaks are missing when the text is copied and pasted. This causes errors when submitting headers to services anti-spam services like SpamCop. This works correctly in the release version, but is broken in the beta.

Agreed with the comments on reporting to spamcop. Why have you made up your own standards!? 1) copy/paste also highlights the underlying email on the main page, not just the msg source, so it copies more than the message source, 2) the header starts with an outlook redirect (prod protection) which makes the real source partially hidden, 3) you've put random newlines in everywhere, which break the header parsing. You've basically made reporting spam HARDER! Why would you do that? At least old outlook only had the second issue! Now your message source tool is almost useless! Just stick to the standards PLEASE! Don't make up your own "standards"!
Copying the source with no formatting really sucks. As already told it now makes for SpamCop reporting worthless, as well as any anti-fraud sites and official police agencies.
No one will spend the effort the put the line breaks in their proper places just to do reporting, and these agencies rely on certain information formatted a certain way to help them track down criminals.
It's possible to switch back to the original version by going to https://outlook.live.com/owa/?path=/fb
Outlook.com no longer has the option to switch back to the original non-beta release version. This now makes it impossible to report spam messages to sites such as spamcop.net.
This is the documentation on the message formatting error returned from spamcop (worked fine in the original release version):
