Question details
The user is encountering an email delivery failure accompanied by the error code 554 5.2.0 STOREDRV.Deliver.Exception.
- Product
- Microsoft Office 365
- Device & OS
- not provided
- Scenario
- Attempting to receive or deliver emails in an Office 365 Exchange mailbox.
- Observed behavior
- Email delivery fails and returns a bounce message citing a MAPI NoSupport Error (554 5.2.0 STOREDRV.Deliver.Exception), which is typically caused by a missing Clutter folder or inconsistent Clutter configuration.
Ensure you have access to the affected user's Outlook on the web credentials or possess Exchange administrator privileges to run PowerShell commands.
Disable the Clutter Feature via Outlook on the Web
Turning off the Clutter feature can resolve mailbox inconsistencies that trigger the delivery exception.
In many cases, the MAPI NoSupport Error is triggered when Exchange attempts to sort mail into a Clutter folder that is missing or improperly configured. Disabling Clutter prevents Exchange from attempting this processing.
Open your web browser, navigate to the Office 365 portal, and log in to Outlook on the web using the credentials of the affected mailbox.
Click the Settings gear icon in the top-right corner of the interface. In the search box, type 'Clutter' or manually navigate to Mail > Automatic processing > Clutter.
Uncheck the box that says 'Separate items identified as clutter'. Click 'Save' at the top to apply the changes and test if emails can now be delivered successfully.
Disable Clutter Using Exchange Online PowerShell
Administrators can quickly disable the Clutter feature for the affected user using Exchange Online PowerShell.
Collect the Bounce Message and Contact Microsoft Support
If modifying the Clutter status does not resolve the 554 5.2.0 error, the issue requires escalation to Microsoft Support.

Frequently Asked Questions
What does the error 554 5.2.0 STOREDRV.Deliver.Exception mean?
This error signifies that the Exchange server encountered an unexpected exception while attempting to process and deliver an email to a specific mailbox, resulting in a complete delivery failure.
Why is the Clutter feature associated with email delivery failures?
If a mailbox's Clutter folder goes missing or its underlying configuration becomes corrupted, Exchange struggles to automatically sort incoming messages. This processing failure triggers the MAPI NoSupport exception and stops the email delivery.
Can I re-enable Clutter after resolving the 554 5.2.0 error?
Microsoft has largely deprecated the Clutter feature in favor of Focused Inbox. It is highly recommended to leave Clutter disabled and transition to using Focused Inbox to avoid repeating this mailbox inconsistency.
What should I do if disabling Clutter does not solve the email bounce?
You should gather the complete Non-Delivery Report (NDR) bounce message and the user's mailbox settings, then open a support ticket with Microsoft 365 Support for advanced server-side troubleshooting.
