Hi,Alexandra Crim
I will provide you with some advice on what to do to contact the school's IT department, whose contact information can usually be found on the school's main website. Look for sections such as “Contact Us” or “Support.” If you can't find it, you can also ask your school's administrative office for help.
If your school uses Microsoft services, you can find more information on how to contact your school's technical support team here. Find the administrator for your work or school account - Microsoft Support
