New Outlook for Windows – Reply/Forward does not include original message (no quoted text, no expander)

Hi @SYV@E

Regarding your issue, after checking at the moment there doesn't appear to be any active incident being recorded related to this behavior in New Outlook for Windows. Since this doesn't appear to be a wider service issue, before contacting Microsoft Support, I suggest trying a few quick checks first to rule out any possible local client-related cause.

• Could you try clearing the New Outlook cache? To do this, close New Outlook completely, press Windows + R, paste olk.exe --devtools. Then reopen New Outlook and test Reply/Forward again.
• 
• • After that, could you also try reinstalling New Outlook to see if that makes any difference? You can do this by going to Settings > Apps > Installed apps, locating Outlook (New) and selecting Uninstall, then reinstalling it from the Microsoft Store and signing back in.

If the issue still persists after both steps, I recommend submitting a support ticket to Microsoft support so it can be investigated more thoroughly. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.

Here’s what your Microsoft 365 Global Admin (IT Admin) should do next:

• Submit a Service Request: The Global Admin should create a service request with Microsoft support to get advanced technical assistance and diagnostics. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.   
• Find Your Microsoft 365 Admin: If you’re unsure who the Global Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin?
• If your subscription is managed through a Microsoft partner or reseller, they can also assist with opening a support request and liaising with Microsoft on your behalf.

Note: If you’re an end-user, please coordinate with your Office 365 Global Administrator to handle these steps. 

When submitting, it helps to include details such as when the issue started, your New Outlook version/build number, that it's 100% reproducible after the recent update, and that it affects multiple accounts and users in your organization.

Also, I recommend asking your IT administrator to report the issue through the Microsoft 365 admin center as well and note that it affects the Outlook experience. This helps ensure the scope of impact is clearly captured.

In the meantime, since both Classic Outlook and Outlook on the web are including the original message correctly, you can continue using either of those as a temporary workaround.

I apologize for redirecting you the related team support, as the moderators in this community don’t have access to the detailed system needed to troubleshoot this effectively due to privacy and security constraints. But Microsoft’s support team has elevated permissions and access to backend systems that we, as community moderators, do not. This ensures your issue is handled with the right tools and expertise and helps you get a faster resolution.

Thank you for your understanding, and I appreciate you taking the time to share your feedback.
