I have not been receiving a few emails recently. I know of at least two emails that were sent to me this Friday that I never received. These were part of an email communication that I had sent to my siblings, and they responded by replying to my email, but for some reason the others in the list got them, but I missed getting two of them. I got one yesterday, and I can see that while I was on the list on two of them from the email chain, I never actually got the emails in my inbox.
This obviously is very serious, as I will start losing confidence in Outlook!
Can the Outlook.com team please investigate and let me know what the problem is?

I have been noticing this problem since August 23, 2013
