Before you start

Ensure you have your exact Microsoft 365 organizational login credentials ready, and verify whether you are currently logged in with a personal, work, or school account.

Solution 1Recommended

Verify Account Type and Log In with a Work or School Account

Ensure you are using the correct organizational account instead of a personal account to bypass permission restrictions.

Microsoft 365 Quarantine pages are strictly bound to organizational directories. If your browser automatically logs you in with a personal Microsoft account, access will be denied even if the email address is similar.

Frequently Asked Questions

Why does Microsoft 365 reject my personal account for email quarantine?

Microsoft 365 security policies restrict backend portal access to authorized organizational (work or school) accounts. Personal Microsoft accounts, even if linked or similarly named, do not have the required Active Directory permissions to view the organization's quarantine data.

Where can I find the Microsoft 365 Quarantine page?

If you have the correct permissions, you can access the Quarantine page by logging into the Microsoft 365 Defender portal and navigating to the 'Email & collaboration' section, then selecting 'Review' and clicking on 'Quarantine'.

Can standard users release their own quarantined emails?

It depends on the security policies set by your organization's IT administrator. Admins can configure settings to allow standard users to review and release spam or bulk emails, while high-confidence phishing or malware emails are usually restricted to admin-only release.
