$ quick answer

Fake file-sharing emails exploit familiar Microsoft workflows. The safest pattern is to verify the sender, inspect the destination link, and access shared files through the official Microsoft 365 environment rather than the email itself.

$ about this initiative

A short awareness guide on fake OneDrive sharing emails that trick users into entering Microsoft credentials on imitation sign-in pages.

$ How these attacks work

Attackers send fake document-sharing emails that look familiar enough to trigger a fast click. The goal is to move the user to a fake sign-in page and capture credentials.

$ What users should do instead
  • >Open Microsoft 365 directly and look for the shared file there
  • >Check the full sender address and sharing context
  • >Report suspicious sharing prompts to the IT or security team

$ frequently asked questions
What makes fake OneDrive emails convincing?

They imitate a workflow users already trust: file sharing, collaboration, and Microsoft sign-in prompts. The content feels ordinary, which lowers suspicion.
