Salesforce Email Verification Fix

I need assistance with Salesforce. My Outlook emails are showing up to the recipient as unverified. I am the only user and admin on the account. I have already added my Outlook email, but I don't know how to verify it.

Ideal skills and experience:
- Salesforce administration expertise
- Experience with Outlook integration
- Strong problem-solving skills
- Ability to provide clear, step-by-step guidance
