microsoft365.com blocked?

I access Microsoft365.com to check my work email on my laptop and my phone and the past couple of days I've been getting an error...  A few other people I work with who have Xfinity have also complained that this stopped working and when I check the Security Risk History in the Xfinity App on my phone I see the message "Content from microsoft365 was blocked and is classified as: Phishing/Other Frauds."   The only options I have is to allow access for 1 hour or to disable the Advanced Security completely....
