Using older versions of Outlook for Mac for personal email and calendar
Hey there! Nice to meet you!
Since you are still unable to sign in despite successful password resets, this indicates that the account is temporarily blocked due to multiple failed sign-in attempts/unusual login pattern.
It is also possible that someone may have been trying to sign in to your account repeatedly which triggering the system to detect unusual activity.
Please perform these steps to resolve an account block:
- Perform a password reset using an InPrivate window or Incognito.
- Try using different devices and network services.
- Wait 24 hours to perform a password reset, but please make sure not to reset the password within that timeframe, as this may reset the lock cooldown.
- If it doesn't work after 24 hours, try waiting exactly 48 hours before resetting the password

Once you have regained access to your account, I suggest following the guide from this thread to prevent unauthorized logins: https://learn.microsoft.com/answers/questions/4049625/someone-is-repeatedly-trying-to-access-or-hack-my?forum=windows-all&referrer=answers
