Feature Retirement: Tonal Rewrite in Outlook Web Access (OWA)

Feature Retirement: Tonal Rewrite in Outlook Web Access (OWA)

The Tonal Rewrite feature in Outlook Web Access will retire on September 15, 2025. Users will transition to using Copilot in Outlook for advanced, context-aware rewriting and tone adjustments, requiring no admin action. This change enhances writing flexibility and efficiency with AI-powered tools. Introduction Starting September 15, 2025, the Tonal Rewrite preview feature in Outlook Web Access (OWA) will be retired.  Why This Change? The Tonal Rewrite experimental feature was introduced to help users improve sentences tone in emails by proactively offering AI-generated alternatives. While it has been a valuable tool for many, we are evolving our writing assistance capabilities to better align with how users write and revise content today using modern Copilot capabilities. When this will happen This feature will no longer be supported after September 15, 2025. How this affects your organization Tonal Rewrite was introduced as an experimental feature to help users improve the tone of their email content using AI-generated suggestions. With its retirement, users will no longer see tonal suggestions in OWA. Instead, users can leverage Copilot in Outlook, which offers: Context-aware rewriting: Highlight text and generate refined alternatives. Prompt-based editing: Ask Copilot to rewrite, summarize, or adjust tone using natural language. Iterative refinement: Use Fine tune your rewrite to guide Copilot through multiple revision rounds. These enhancements provide greater flexibility and control, improving writing efficiency and confidence. What you can do No admin action is required. We recommend encouraging users to explore the Auto-Rewrite capability via Copilot in Outlook: Highlight the text to revise. Click the Copilot icon. Select Auto-Rewrite or Change Tone. Review and apply the suggestion. Compliance considerations We appreciate your feedback and look forward to supporting your writing journey with even more powerful tools. No compliance considerations identified, review as appropriate for your organization. Message ID: MC1139486
