Office 365 Email Quarantine Fix
Budget: $10 – $30 USD
Internal and external messages in our Microsoft 365 tenant are landing in quarantine, effectively blocking everyone from sending or receiving mail. Safe-sender lists have already been reviewed and confirmed, yet the issue persists for every user—staff and outside contacts alike.
What I need is a swift deep-dive into Exchange Online Protection / Microsoft Defender policies, transport rules, and any conditional access or connector settings that could be flagging legitimate traffic. After identifying the root cause, I expect actionable remediation (policy tweaks, rule rewrites, or other configurations) followed by a validation test that shows clean mail flow end to end.
Deliverables
• Root-cause report outlining exactly why messages were quarantined
• Updated or new policies/rules applied in the tenant
• Verification test results confirming successful delivery for both internal and external addresses
• A brief hand-off note so we can maintain the fix going forward
A solid track record with Office 365 security, EOP, and Defender for Office 365 is essential; PowerShell fluency for tenant-wide checks is a plus. I will provide global admin access in a secure session once we agree on the timeline, and I’m ready to start right away.
