我的OFFIICE365 通知停用,但我不知道當初設定的帳號和金鑰(序鑰), 要如何處理? 如果要續用,要如何作業?

Hello,

There is no need for a product key in order to activate Microsoft 365 apps, you just need to sign in with the account where the office license associated with.

To further check on which is the correct account the Office license associated to, just to go to account.microsoft.com/services > then from the subscription, you can see there if the subscription is active on the account you signed in. If its not there, then try the other account to check.

Office 365 企業版表示是組織提供，看是你學校或你公司，如果還在組織內，聯繫組織管理員詢問。

你不能自行在組織帳號續約。

圖上 管理帳號 按鈕按下去，會顯示哪個帳號提供的授權。
