I work as postmaster for a university in Germany. It is widely known in these circles that mails get "lost" at O365/Live even though we have an official "250 Requested mail action okay, completed" in our logfiles, good reputation, are not listed in any blacklists, etc. I and a lot of my colleagues in other universities started advising staff and students against forwarding e-mails to Microsoft's mail services because of these issues. If someone comes in and wants help with "I don't receive all my mails" the first question is always if they are using O365/Live/... - and suggesting to disable the forwarding and keep the emails local. It is absolutely depressing to not be able to figure out why this happens or even if. If our mails did get rejected, that would be fine. At least we'd know something might be wrong. Instead I have to deal with abuse messages from Microsoft more or less daily, because users are too stupid to understand the difference between junk and trash.
