Locked out of sending emails.

My account got hacked. I changed all my passwords and can now receive emails but I cannot send any. I get a message telling me im not a valid sender anymore because im a suspected spammer and contact my admin. I am the admin, but I can't seem to figure out how to solve this issue. help please.

Hi @JasonSymonds-6871

Agree with the suggestions above, you could manage the blocked users from Microsoft 365 Defender portal Or using Exchange Online PowerShell

 Get-BlockedSenderAddress
 Remove-BlockedSenderAddress -SenderAddress <emailaddress>

Make sure you have below roles to perform the operation
