Answer 1

You will need to use the Sign in Helper to try to unblock it https://support.microsoft.com/en-us/accounts-billing/manage/unblock-my-outlook-com-account

Microsoft's official document says sending limit is up to 500. But that number can be misleading. In reality, 500 is only the absolute maximum under ideal conditions, and I have rarely seen users reach it.

Many users hit the daily sending limit at a much lower number. Unfortunately, no one can tell you exactly what your limit is because it is dynamic and varies from one account to another. It works somewhat like a credit score and may be affected by factors such as account history, normal usage patterns, whether the account is verified, whether it is free or paid, the type of content being sent, and the number of recipients.

From what I have seen while helping users here, sending one message to many recipients is one of the biggest factors. Email signatures, HTML formatting, and links may also increase the chance of triggering the anti-spam system. I have seen some users hit the limit after sending a single email to only 10 or 20 recipients.

Unfortunately, even after changing your sending habits, the limit may not improve immediately. It can take time for the account's sending reputation to recover.

I am sorry I cannot give you a more precise number, but there is simply no fixed limit that applies equally to every user.
