Hi Decovan,

Based on your description, your Microsoft tenant has been flagged due to exceeding the Exchange online limits and is being blocked from sending emails. If only one user is affected, you can remove the user from the restricted entities. If all users are affected, you need to submit a support request from the admin center to remove the block.
