want to get ids of some poeople

Dear @MEHUL PANCHOLI ,

Thank you for posting your question in the Microsoft Q&A forum.

Please understand that our forum is a public platform, and we will modify your question to cover your organization domain name in the description. Please notice to hide these personal or organization information next time you post error or some information to protect personal data.

Based on your description, unfortunately, as a moderator, we can’t access or reveal other people’s identities or device IDs for you, and we can’t pull sign‑in logs from your tenant. However, only a Microsoft 365/Entra ID admin (not a regular user) can see the full sign‑in logs (IP/device, client app, location) and audit trail needed to identify who accessed your account. This is by design for privacy and safety.

So, in this case, I recommend you contact to your IT/admin to check some suggestions below:

1.Check Entra ID sign‑in logs for your account

• Go to Microsoft Entra admin center > Monitoring & health > Sign‑in logs.
• Filter by your user and by the incident time window (e.g., yesterday during your class).
• The log shows user, client app, IP address, device details (device ID, OS, browser), and success/failed status. Admins can export to CSV

2.Pull Microsoft 365 audit logs (Teams activity)

• In Microsoft Purview > Audit > search for Teams activities (if auditing is enabled—Audit Standard keeps logs by default).
• This helps correlate meeting joins/leaves and other Teams actions within the timeframe

Here are some more details information link: Manage meeting attendance reports in Microsoft Teams Learn about the sign-in log activity details

I hope information above can help you resolve your issue, if you have any other questions, please feel free to reach out.
