Microsoft Teams Right‑Click Paste Disabled by Edge Update Bug Impacts Corporate Users

What Happened – A Microsoft Edge browser update introduced a regression that disables the right‑click “Paste” option in the Microsoft Teams desktop client. Users see the Paste menu item greyed out, preventing URLs, text, and images from being pasted via the context menu.

Why It Matters for TPRM

  • Reduces employee productivity and may delay critical communications.
  • Highlights the dependency of SaaS collaboration tools on underlying browser components.
  • Indicates the need for rapid vendor communication and patch‑tracking in third‑party risk programs.

Who Is Affected – Enterprises, government agencies, educational institutions, and any organization that relies on Microsoft Teams for internal collaboration (across all industries).

Recommended Actions

  • Notify end‑users of the temporary workaround (keyboard shortcuts Ctrl/Cmd + V).
  • Monitor Microsoft’s patch rollout and update Teams promptly once the fix is released.
  • Review vendor SLA clauses for “critical functionality” outages and ensure remediation timelines are documented.

Technical Notes – The issue stems from a code regression in the Edge rendering engine that Teams leverages for certain UI functions. No CVE has been assigned; the bug does not expose data or allow code execution. Affected data types are limited to clipboard content (text, URLs, images). Source: BleepingComputer
