Dear @PHA and @Toni
Welcome to the Microsoft Q&A Community!
Thank you for letting us know about the drag‑and‑drop issue.
I have tested the scenario on the New Outlook versions 1.2025.1218.100 and 1.2026.112.400, and the drag‑and‑drop to folders in Favorites is working as expected on those builds. To give you the smoothest experience, could you please make sure your Outlook is fully up to date? In New Outlook, select Settings (gear) > About Outlook to confirm the version number. Kindly update Outlook to the latest version and restart Outlook after the update completes.
If you’re already on the latest version and the problem still occurs, please send your feedback from Outlook or via the Feedback Portal so Microsoft Developer team knows about the issue.
Please understand that as a forum moderator, I don't have permission or access to products changes. Hence, your feedback is valuable in getting Microsoft acknowledge of the issue.
- In New Outlook, go to Help > Feedback and include a brief description (e.g., “Can’t drag and drop emails to Favorites in shared mailbox folders”) along with screenshots if possible.
- Here is the link of the Feedback Portal where you can publicly share your feedback: Outlook · Community
If this affects more than half of your organization, please ask your Microsoft 365 admin to open a ticket in the Microsoft 365 admin center. This helps Microsoft recognize the scope and prioritize a fix.
For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. Moreover, kindly ask the admin to report the issue via Service Health following the instructions outlined via How to check Microsoft 365 service health - Microsoft 365 Enterprise | Microsoft Learn. As many users report the issue, Microsoft will identify it as an incident and officially announce the situation.
I know this is frustrating, and I appreciate your patience while we work through it together. Please know that I'm here to update you with news from Microsoft and am willing to help.
