⚠️ Major Change – Teams Meeting URL Validation
This update has already been revised three times this month, which makes it one to keep a close eye on. Microsoft has marked it as a Major Change in the Message Center, and with updates coming this frequently, you can’t just read it once and move on.
Starting September 30, 2025 (Nov 30 for GCC/DoD), Microsoft Teams will begin validating meeting join URLs. The goal is to prevent altered or rewritten links from being blocked as malicious. Safe Links and Outlook add-ins are unaffected, but organizations using third-party URL rewriting tools must ensure Teams join links are excluded to avoid join failures.
