Hello,
We've had a couple of users experience SmartScreen blocking O365 file sharing links (SharePoint/OneDrive) sent to and from users on our own domain. Here is what they receive:
The link is just an xlsx file that is parked on a user's OneDrive. I've inspected the file, and it does not contain any active content that could be construed as malicious. Furthermore, the user created a second link to the same document, which is not blocked by SmartScreen.
The users themselves claim that they did not report the link as malicious (of course, users never lie, right?). Based on what I am reading, though, SmartScreen will display this message whether a person reported it or Microsoft's algorithms have flagged it:
Microsoft Edge support for Microsoft Defender SmartScreen | Microsoft Docs
I realize I can AllowList our SharePoint domain for SmartScreen, but I don't really want to give up the protection entirely.
We've had Edge deployed companywide since last August, and have had no such reports until now. We have around 1100 active users and many of them use the O365/OneDrive/SharePoint ecosystem with great frequency.
There are a few things I don't like about this:
Has anyone else run into this behavior in your organization? I would be interested to know if there are other options for dealing with this besides having folks re-share everything or sending a report to MS and hoping it gets approved on their side.

Check with the host and may be there is malware in the host and ask them to investigate for security issue. May be it contains some malicious contents.
