Welcome to the Microsoft Q&A forum
I would like to provide you with the following information:
Since your Outlook account is a business account, it is managed and configured by the tenant’s administrators.
To retrieve Outlook sign‑in logs for a company account, the account must have the appropriate administrator permissions in the tenant. Without these permissions, the sign‑in logs cannot be accessed.
In many organizations, there are also security policies that restrict accounts to sign in only within the office network or the company’s internal environment.
In this case, you can follow the steps below to check the sign‑in logs:
Note: The steps below require administrator permissions in the tenant. If you do not have admin access, please contact your organization’s IT department for assistance.
Step 1: Go to entra.microsoft.com
Step 2: Select Users > All users, then find and select your account
Step 3: Select Sign‑in logs
Here, you will be able to view the sign‑in activity for the account, including both successful and failed sign‑in attempts, along with the detailed reasons.
I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.
Thank you for your patience and your understanding. If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.
I look forward to continuing the conversation.
