Hi @VCG COUNCIL
Thank you for contacting Microsoft Q&A Support.
To help you unblock your account and resume sending emails, I’d first need to confirm:
Are you using a Microsoft 365 business account managed by your organization, or a personal Outlook.com account?
This will help determine the right steps:
If you're using a personal Outlook.com account:
- Visit Unblock my Outlook.com account
- Follow the instructions to verify your identity and unblock your account
If you're using a business account:
- Please contact your IT administrator
- They can check if your account has sending restrictions, mailbox limits, or if it was flagged for unusual activity
If you’re unsure who the Global Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin? - Microsoft Support.
Also, if you received a specific error message when trying to send, please share it here it will help me provide more targeted guidance.
Thank you again for your patience and for choosing Microsoft Q&A forum.
