译文说明

UserAccountNotFound - 要登录此应用程序，必须将帐户添加到目录中。发生此错误的原因可能是用户输入了错误的用户名，或者不在租户中。应用程序可能选择了错误的租户进行登录，并且当前登录的用户无法执行此操作，因为它们不存在于您的租户中。如果该用户应该能够登录，请将其添加为访客。请参阅此处的文档：添加 B2B 用户。

官方说明 · 原文

UserAccountNotFound - To sign into this application, the account must be added to the directory. This error can occur because the user mis-typed their username, or isn't in the tenant. An application might have chosen the wrong tenant to sign into, and the currently logged in user was prevented from doing so since they did not exist in your tenant. If this user should be able to log in, add them as a guest. See docs here: Add B2B users.
