No. It will do things when shuffling the email through its various scanner platforms that will make their systems think the original sender is outlook's systems. So then when their later downstream service looks at the email it's like "cool an email from Outlook, let's see if Outlook is allowed to send for this domain...hmm...seems like outlook isn't allowed to send and I'm supposed to reject emails coming from unapproved senders so rejected!"
The way it sometimes bounces emails around in their own systems lead to them sometimes mixing up who actually originally sent the message. This causes all kinds of problems and seems entirely unique to their crappy setup.
