A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
Hi @Shubh
Regarding your issue, it looks like you've genuinely exhausted all the troubleshooting steps available on the user side signing out of every Microsoft app, clearing credentials and passwords, reinstalling, clearing Safari data, checking Authenticator and device profiles, and even running RemoveAllAccounts in Edge. Since the deleted account still persists after all of that, this has gone beyond what can be resolved through the standard steps. As you're using a business subscription, I'd recommend reaching out to your IT (Global) admin, who can raise a support ticket with Microsoft Support on your behalf to investigate this further and help resolve it for you.
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 you reach out, it'll help to mention everything you've already tried so they can skip straight to the deeper investigation rather than repeating the basics.
Before submitting the ticket, make sure the Support Assistant is turned Off as several customers have reported that when the Support Assistant is enabled, the Contact Support option may not appear.
As shown in the screenshot, simply switch Support Assistant > Off, then enter your issue description. Once disabled, the Contact Support button should appear, allowing you to submit the ticket normally.
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.
Hopefully they will be able to help with your issue and if you have any other questions or need further assistance, feel free to ask.
