Arlo Pro email alerts not arriving in my Hotmail account, but works with gmail.

[amroyounes]

I have had the same issue since late 2018.  I finally spent time this past weekend debugging the issue.  I went to my hotmail account, and added both alerts@arlo.com and arlo.com to the safe list domains.  I checked my junkmail and there are no arlo alerts.   I enclosed a screen shot of my hotmail config.

Lastly, I modified the alert policy to email me both at hotmail and at my gmail account.  i then triggered motion on my camera and I consistantly receive email alerts to gmail but not to hotmail.  

I contacted hotmail support, and they responded with the following:
