Resolve Outlook Email Delivery Issue

Job ID: 37904381

Budget: $10 – $30 USD

I'm experiencing a puzzling problem with my Outlook email service across all my devices. Every time I attempt to send an email to an address with three or more characters following the @ symbol, I get a "mail delivery failed" error. Interestingly enough, email delivery seems to be working fine for addresses with only two letters after the @.

Here's an overview of what I need from a freelancer:

1. Successful Diagnosis: Pinpoint the cause of this issue.
2. Solution Implementation: Fix the problem so that I can send emails to any valid email address from my devices without restrictions.

Ideal Skills and Experience:

* Strong understanding of email service providers, particularly Outlook.
* Experience solving similar email delivery issues.
* Ability to troubleshoot across multiple devices.
