Hi @Rithesh Chajed

Please note that we are not Microsoft support, and this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, do not have backend access and cannot directly intervene in Microsoft products or features. Our role is limited to providing technical guidance and best practice recommendations based on reported issues, requests, or ideas. 

Based on my research, you could consider trying the steps below: 

1/ Sign out of all accounts in the Microsoft 365 applications, and then completely close Outlook, Teams, OneDrive, Word, Excel, and other Office applications. 

2/ Open Settings > Accounts > Access work or school and check whether the affected business account is listed. 

+If the account is not listed, select Connect and add the business account. 

+If the account is listed, select it and choose Disconnect. Restart the computer, return to Access work or school, select Connect, and add the account again. 

Note: If this is an organization-managed device, please contact your IT administrator before disconnecting the account. 

3/ After restarting the computer, open one Microsoft 365 application, sign in with the affected business account, and check whether the issue persists. 

I hope these steps provide some additional troubleshooting guidance. I look forward to any updates or results you may be able to share.
