Check Microsoft 365 Service Health Dashboard
Use this solution to confirm if the quarantine release error is caused by a known Microsoft backend outage or service degradation.
The 'Hygiene DAL' error often points to a server-side issue within Microsoft's Exchange Online Protection infrastructure. Checking for active incidents can save you from unnecessary local troubleshooting.
Log in to the Microsoft 365 admin center using your administrator credentials.
On the left navigation menu, go to Health and select 'Service health'.
Look for any active incidents or advisories related to Exchange Online, Microsoft Defender for Office 365, or email delivery delays. If an issue is posted, Microsoft engineers are actively working on a fix.
Clear Browser Cache and Check Network
Use this method if there are no reported service outages to rule out stale session tokens or local browser conflicts causing repeated bad requests.

Frequently Asked Questions
What is the 'Hygiene DAL' in Microsoft 365?
The Hygiene DAL (Data Access Layer) is a backend component of Microsoft's Exchange Online Protection and Defender architecture. An error originating here usually indicates a temporary server-side database timeout or connectivity issue within Microsoft's own infrastructure.
Why can I delete quarantined messages but not release them?
Deleting a message simply removes its database entry, which is a lightweight operation. Releasing a message requires routing it back through the Exchange transport pipeline for delivery, which is more complex and can fail if there are active transient server conditions.
How long do transient conditions usually last in Microsoft 365?
Transient conditions are typically temporary network or server hiccups that resolve automatically within a few minutes to a few hours. If the issue persists longer, it is likely tied to a broader service incident that Microsoft engineers are actively addressing.
Will clearing my browser cache actually fix a backend Microsoft error?
While the Hygiene DAL error is primarily server-side, a corrupted browser cache or stale session token can sometimes trigger repeated failed requests. Clearing your cache ensures you are sending a fresh, valid request to the quarantine portal, ruling out local conflicts.
