Using New Outlook on Windows for professional communication and productivity
Good day Joey, and I'm sorry to hear that your organization is experiencing these disruptive issues.
Just to gently clarify before going any further, this forum is separate from Microsoft Support. I can only share publicly available documentation, testing observations and general troubleshooting guidance. I don't have access to Microsoft's internal diagnostic tools, engineering investigations or product development backlogs.
Since the New Outlook synchronization and shared mailbox issues are affecting multiple users within your organization, I recommend opening a support request through the Microsoft 365 admin center > Support > Help & Support so they can further investigate the environment and collect diagnostic logs if needed for more in-depth troubleshooting.
- Turn off the "Support Assistant" feature.
- Use the keyword "Support" to quickly bypass automated suggestions > Select Contact Support.
- In the ticket description, please clearly describe the issue, including any error messages or codes and the steps you’ve already tried. You can also attach screenshots or screen recordings.
- Additionally, sharing your preferred contact times may help the support team handle the case more efficiently.
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.
I wish I could help more directly, but as a fellow user in this community, providing these steps is the best support I can offer. I hope the support process goes smoothly and your issue is resolved soon. If you have any questions, please don’t hesitate to reach out at any time.
Thank you for your patience and understanding.
