使用 Android 版 Outlook 進行個人電子郵件與行事曆管理
Hi,
Is this your first time logging in to your phone using your Microsoft account?
Try going to incognito mode and log in from there. If the issue persists, try signing in using “Other ways to sign in” instead of entering your password. From there, choose to receive a code through your linked verification methods.
Also, use the sign-in helper tool to log in: https://go.microsoft.com/fwlink/?linkid=2214157
