問題

在 Microsoft Entra ID(Azure AD)的 App registrations 建立 App (Supported account types 設定為 Accounts in this organizational directory only (你的組織 only - Single tenant))並建立它的 Certificates & secrets ，然後建立 Azure Bot 並設定 Microsoft App ID ，Type of App 設定為 Single Tenant 對應到上述的 App。
透過 App 的 clientId 及 secrets 到 https://login.microsoftonline.com/botframework.com/oauth2/v2.0/token 取得 token 時，發生AADSTS700016的錯誤。

解決

依從 Microsoft Entra ID 帳戶登入服務要求存取權杖說明，
要透過 https://login.microsoftonline.com/botframework.com/oauth2/v2.0/token 取得 token ，
App 的 Supported account types 及 Azure Bot 中 Microsoft App ID 的 Type of App ，要設定為 Multi Tenant。
如果是 Single Tenant，那取得 token 的 url 要改成 https://login.microsoftonline.com/<你的-TENANT-ID>/oauth2/v2.0/token
這樣就不會有問題了哦~
