校園版微軟帳號於2024/07/01遭到學校移除，不知道該如何找回？

我的學校在2024年7月1號後開始刪除非在學學生的校園版微軟帳號（我於2023年1月畢業，帳號因此遭到刪除）。
我的微軟帳號裡存放了重要資料，致電學校後，學校表示無法找回，學校建議我去諮詢微軟。
我不知道該如何復原該帳號。
我已經致電過台灣微軟，但是皆無專人接聽服務。

Since July 1, 2024, my college started deleting the accounts of non-current students (I graduated in January 2023, so my account is deleted by college because of my identity as non-current student).
There are vital information stored in that account.
I called my school and they said they can't recover my account and they suggested me to consult Microsoft.
I don't know how to recover the account.
I have called Microsoft Taiwan, but no real person is available to answer my call.
