Good day أنس شحاده,  

Thank you for taking the time to share your experience.  

I truly appreciate the time and effort you’ve already invested in troubleshooting this issue on your own. You’ve completed all the appropriate end‑user troubleshooting steps, which is very helpful. Currently, I’ve reviewed the advisories and incidents listed in the Microsoft 365 admin center and didn't find any related notifications.  

• As the next best step, I strongly recommend contacting your IT administrator to submit a support ticket through the Microsoft 365 Admin Center > Support > Help & Support for further investigation.  
• 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. They can also attach screenshots or screen recordings.  
• Additionally, sharing their preferred contact times may help the support team handle the case more efficiently.     

A Microsoft technical support engineer can conduct a remote session to review the issue in detail, validate backend configurations and run any required synchronization or diagnostic tools. If necessary, the case can be escalated to a specialized team for more in‑depth analysis and resolution.  

As a forum moderator, I would like to clarify that my role is limited to sharing public documentation, testing observations and general troubleshooting guidance. I don't have access to internal diagnostic tools, engineering backlogs, or build level investigations.  

If you have any questions or need further support, please don’t hesitate to reach out at any time. Thank you for your patience and understanding.
