How can I allow emails from shutterfly?

 

Look at this error:

 

10/30/2013Soft BounceMessage bounced
Remote host response: 550 SC-001 (BAY0-MC1-F54) Unfortunately, messages from 74.121.38.132 weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.

Our company is using Outlook.com with our own custom domain, set up with the appropriate MX records on our web host. My colleague occasionally has trouble sending me e-mails, usually a reply or forward. They will come back to him with a bounce message.

 

However, today he forwarded me a message. As far as he could tell, the message sent OK, with no error message being returned to him. I never received the e-mail, not in my Inbox or Junk Mail folders.

 

I reviewed the article "I'm not receiving emails sent by my family or friends". Of its suggestions, the only one not in place already was adding my colleague to my contact list. However, it should not be necessary to have someone in my contact list in order to receive an e-mail from them, in the junk mail at the very least.

 

This is a serious issue, as we cannot operate with e-mails not being delivered without warning.

Since 8/15/13 my outlook.com account is not receiving emails--it doesn't generate a "bounce" message to the sender, either. I tested this after I spotted the problem only yesterday. I tried to share a dropbox folder and dropbox was unable to verify my email account--repeatedly. I thought it might be a problem with dropbox, but later I tried to recover a password from an old gmail account and that got the same result. I've duplicated the problem with several browsers, including mobile browsers and specific apps. Exactly the same result every time. I see several similar threads here--an honest description of the problem, which appears to be on the Microsoft end of the process, would be very helpful. I've checked everything I can from here, and I've purged and reinstalled the outlook.com app on my phone and tablet. I've changed my password in the process. I've sent test emails from another outlook.com account as well--same result. Nothing shows up in the target inbox, no bounce message. The only indication of a problem is that the email doesn't arrive. If I didn't have multiple email accounts I'd have had to wait until some sender got ticked off enough to call me or something. Not good. Better communication would be nifty--but that isn't something Microsoft is known for. Maybe a twitter account similar to the microsofthelps account that just posted outages or known issues. That would at least help those of us with Twitter accounts. So where are we on this? I really need that account to work, obviously, but I understand stuff happens and there is a large user base involved. A solution would be best, but information will do in the mean time.
