    Hi Yogesh,

    Since auto-archiving, recreating the Outlook profile, and even provisioning a brand-new mailbox haven't resolved it, the most effective next step is using your admin credentials to submit a support request through the Microsoft 365 Admin Center.

     Microsoft also provides customer service phone numbers based on your region. You can find the appropriate contact number here: Customer service phone numbers - Microsoft Support 

    This route ensures that a Microsoft support engineer can initiate a remote session to investigate backend configurations, run advanced diagnostic tools, and, if necessary, escalate the case to specialized teams with access to internal systems and logs. These backend resources are essential for resolving issues that go beyond what’s visible in the user interface.

    I hope this helps you resolve the issue quickly. I’m glad to assist and truly hope the information provided has been useful. Please feel free to reach out anytime if you need further assistance.
