Falcon Sandbox is explicitly mentioned - which is a middleware that can be installed on various communication platforms (usually enterprise): https://www.crowdstrike.com/products/threat-intelligence/fal...

Microsoft has "safe links": https://learn.microsoft.com/en-us/microsoft-365/security/off... - Chrome has its own thing, but there are also tons of additional hand-rolled similar features.

My main annoyance is when they kill a one-time use URL.

Do you know if safe links is guilty of the issue in the OP?

I suspect not because Microsoft is using their own internal system.

However, it likely exposes the content internally to Microsoft.

They do 100% break Salesforce password reset links, which is a major PITA.
