User impact: Users’ links in multiple browser-based Microsoft 365 services may not be properly evaluated by SafeLinks.<\/p>\n

More info: This issue impacts URL links contained in the following Microsoft 365 services:
– Microsoft Teams for the web
– Outlook on the web
– Microsoft 365 for the web<\/p>\n

This impact is limited to users who have third-party cookies disabled in their web browser. While we work to resolve this issue, users can bypass the impact where possible by enabling third-party cookies in the web browser.<\/p>\n

Current status: Our investigation has determined that recent updates to the affected web browsers to enhance security against third-party cookies are preventing the affected services from leveraging SafeLinks as expected, leading to impact. We’re evaluating potential methods to resolve this issue and remediate the impact.<\/p>\n

Scope of impact: Your organization is affected by this event, and users leveraging SafeLinks using a web browser with third-party cookies enabled in some browser-based Microsoft 365 services may be impacted.<\/p>\n

Root cause: Recent updates to the affected web browsers to enhance security against third-party cookies are preventing the affected services from leveraging SafeLinks as expected, leading to impact.<\/p>\n
