Problems with E-mails from Facebook

Hi all, hope you can help me because I'm stumped. I don't know if this is a Shaw problem or a problem with my e-mail client. I very rarely (if ever) use Shaw's webmail. Instead I use Microsoft Outlook as an e-mail client to retrieve my e-mail from Shaw. I've never had a similar problem (and I'm talking on the order 15 years plus). Recently I had occasion to try to reset my password on my Facebook account. Their automated process on their web page kept telling me they e-mailed me and sent a six digit code to authorize the password reset. I tried multiple times over multiple days -- never received any e-mails via Outlook. Getting suspicious I decide to go to Shaw's webmail to check. There they all were, at least a dozen e-mails from Facebook -- but Outlook never retrieved a single one. Very frustrating! I don't have ANY rules setup in Outlook to block or divert or delete e-mails, so what's going on? Is Shaw somehow blocking these e-mails (not really blocking because there they are on the Webmail page) or not delivering them for some unknown reason? Like I said, this has never happened to me before. I've always received all e-mails in a timely manner (I have Outlook setup to check every 5 minutes for my main account and every half-hour for my other accounts). I even receive all the unwanted spam and phishing e-mails. But for some reason these ones from Facebook never made it to my Outlook client. Outlook client is from MS Office Pro 2010 ver. 14.0.7116.5000 if it matters.
