How to unblock my email address so I can send email in MS365 outlook.

I sent an email to just over 200 recepients and it failed to send and now blocks all my sent emails. I can receive but not send. Other people on the same domain are not affected and can send and receive email. What did I do wrong and how do I correct it?

Thanks!!!!!

    Hi @Leonard Bliss

    Welcome to our forum!

    Based on your description, it looks like you've sent emails to a large number of recipients. It is likely that it was automatically blocked by being identified as spam.

    Are there any error messages? Try sending emails to only a small number of users at once to check if there are any discrepancies.

    To unblock you, you'll need to contact your recipient to add you to your safe list.
