Akademik iletişim ve zamanlama için Windows üzerinde Yeni Outlook'u kullanma
Hello Emre Kandil,
Good day to you and thanks for your post in Microsoft community.
As per your description, you are using School account and if you are an end user/if you are admin, but other user has admin rights, it is suggested to contact your admin and ask admin to reset the Authentication method for your account. Admin can do it by follow Manage user authentication options. (If you are not sure who is your admin, can refer this How do I find my Microsoft 365 admin? - Microsoft Support).
If you are the admin only and can’t access your account, it is suggested to contact Data Protection team, because we are from community team and we are not authorized to reset any user/admin account. Data Protection Team is the only support team to check and reset account. To find contact number of Data Protection team, please check Find Microsoft 365 for business support phone numbers by country or region - Microsoft 365 admin | Microsoft Learn or Global Customer Service phone numbers - Microsoft Support.
Thank you so much for your precious time and co-operation.
Sincerely
Nafis Iqbal Shuvo | Community Moderator
