Usando o Outlook para Android para gerenciar e-mails pessoais e a agenda
Hey there! Nice to meet you!
If I may ask, may I know the exact error messages/codes upon attempting to sign in to your email account?
Have you forgotten your account's password by any chance?
Do you see any unfamiliar email address/phone number upon signing in to your account?
In the meantime, please try to follow the Sign-in helper tool in case this would work through this link:
Best regards,
Darhyl
