In Microsoft 365 organizations with Exchange Online mailboxes, admins can use the Submissions page in the Microsoft Defender portal to submit messages, URLs, and attachments to Microsoft for analysis. There are two basic types of admin submissions:

• Admin-originated submissions: Admins identify and report messages, attachments, or URLs (entities) by selecting Submit to Microsoft for analysis from the tabs on the Submissions page as described in the Admin-originated submissions section.

  After the admin reports the entity, an entry appears on the corresponding tab on the Submissions page (anywhere except the User reported tab).

• Admin submission of user reported messages: The built-in user reporting experience is turned on and configured. User reported messages appear on the User reported tab on the Submissions page, and admins submit or resubmit the messages to Microsoft from the User reported tab.

  After an admin submits the message from the User reported tab, an entry is also created on the corresponding tab on the Submissions page (for example, the Emails tab). These types of admin submissions are described in the Admin options for user reported messages section.

When admins or users submit messages to Microsoft for analysis, we do the following checks:

• Email authentication check (email messages only): Whether email authentication passed or failed when it was delivered.
• Policy hits: Information about any policies or overrides that might have allowed or blocked the incoming email into the organization, thus overriding our filtering verdicts.
• Payload reputation/detonation: Up-to-date examination of any URLs and attachments in the message.
• Grader analysis: Review done by human graders to confirm whether or not messages are malicious.

Important

In U.S. Government organizations (Microsoft 365 GCC, GCC High, and DoD), admins can submit email messages to Microsoft for analysis, but the messages are analyzed for email authentication and policy hits only. Payload reputation, detonation, and grader analysis aren't done for compliance reasons (data isn't allowed to leave the organization boundary).

Watch this short video to learn how to use admin submissions in Microsoft Defender for Office 365 to submit messages to Microsoft for evaluation.

For more information about how users can submit messages and files to Microsoft, see Report messages and files to Microsoft.

For other ways that admins can report messages to Microsoft in the Defender portal, see Related reporting settings for admins.

What do you need to know before you begin?

• You open the Microsoft Defender portal at https://security.microsoft.com/. To go directly to the Submissions page, use https://security.microsoft.com/reportsubmission.

• You need to be assigned permissions before you can do the procedures in this article. You have the following options:

  • Microsoft Defender XDR Unified role based access control (RBAC) (If Email & collaboration > Defender for Office 365 permissions is Active. Affects the Defender portal only, not PowerShell): Security operations/Security data/Response (manage) or Security operations/Security data/Security data basics (read).
  • Email & collaboration permissions in the Microsoft Defender portal: Membership in the Security Administrator or Security Reader role groups.
  • Microsoft Entra permissions: Membership in the Security Administrator or Security Reader roles gives users the required permissions and permissions for other features in Microsoft 365.

• Admins can submit email messages as old as 30 days if they're still available in the mailbox and haven't been purged by the user or an admin.

• Admin submissions are throttled at the following rates:

  • Maximum submissions in any 15-minute period: 150 submissions
  • Same submissions in a 24 hour period: Three submissions
  • Same submissions in a 15-minute period: One submission

• If the User reported settings in the organization send user reported messages (email and Microsoft Teams) to Microsoft (exclusively or in addition to the reporting mailbox), we do the same checks as when admins submit messages to Microsoft for analysis from the Submissions page. So, submitting or resubmitting messages to Microsoft is useful to admins only for messages that have never been submitted to Microsoft, or when you disagree with the original verdict.

• A Files tab is available on the Submissions page only in organizations with Microsoft Defender XDR or Microsoft Defender for Endpoint Plan 2. For information and instructions to submit files from the Files tab, see Submit files in Microsoft Defender for Endpoint.

Report good email to Microsoft

1. In the Microsoft Defender portal at https://security.microsoft.com, go to Actions & submissions > Submissions. Or, to go directly to the Submissions page, use https://security.microsoft.com/reportsubmission.

2. On the Submissions page, verify that the Emails tab is selected.

3. On the Emails tab, select Submit to Microsoft for analysis.

4. In the first page of the Submit to Microsoft for analysis flyout that opens, enter the following information:

   • Select the submission type: Verify the value Email is selected.

   • Add the network message ID or upload the email file: Select one of the following options:

     • Add the email network message ID: The GUID value is available in the X-MS-Exchange-Organization-Network-Message-Id header in the message or in the X-MS-Office365-Filtering-Correlation-Id header in quarantined messages.
     • Upload the email file (.msg or .eml): Select Browse files. In the dialog that opens, find and select the .eml or .msg file, and then select Open.

   • Choose at least one recipient who had an issue: Specify the recipients to run a policy check against. The policy check determines if the email was blocked due to user or organization policies or overrides.

   • Why are you submitting this message to Microsoft?: Select one of the following values:

     • It appears clean: Select this value only when you don't know or you're unsure of the message verdict and you would like to get a verdict from Microsoft. Select Submit, and then go to Step 6.

     or

     • I've confirmed it's clean: In all other cases, select this value after you've already determined the message verdict as clean. Select Next.

   

5. On the second page of the Submit to Microsoft for analysis flyout that opens, do one of the following steps:

   • Select Submit.

   or

   • Select Allow this message: This option creates an allow entry for the elements of the message in the Tenant Allow/Block List. For more information about the Tenant Allow/Block List, see Manage allows and blocks in the Tenant Allow/Block List.

     After you select this option, the following settings are available:

     • Remove allow entry after: The default value is 45 days after last used date, but you can select from the following values:

       • 1 day
       • 7 days
       • 30 days
       • Specific date: The maximum value is 30 days from today.

       For spoofed senders, this value is meaningless, because entries for spoofed senders never expire.

       When 45 days after last used date is selected, the last used date of the allow entry is updated when the malicious email message is encountered during mail flow. The allow entry is kept for 45 days after the filtering system determines that the email message is clean. For all other values, the allow entry exipres on the defined date (1 day, 7 days, 30 days, or the Specific date).

     • Allow entry note (optional): Enter optional information about why you're allowing this item. For spoofed senders, any value you enter here isn't shown in the allow entry on the Spoofed senders tab on the Tenant Allow/Block Lists page.

6. Select Done.

After a few moments, the associated allow entries appear on the Domains & addresses, Spoofed senders, URLs, or Files tabs on the Tenant Allow/Block Lists page at https://security.microsoft.com/tenantAllowBlockList.

Important

• Allow entries are added during mail flow based on the filters that determined the message was malicious. For example, if the sender email address and a URL in the message were determined to be bad, an allow entry is created for the sender (email address or domain) and the URL.
• If the sender email address is not found to be malicious by our filtering system, submitting the email message to Microsoft won't create an allow entry in the Tenant Allow/Block List.
• When an allowed domain or email address, spoofed sender, URL, or file (entity) is encountered again, all filters that are associated with the entity are skipped. For email messages, all other entities are still evaluated by the filtering system before making a decision.
• During mail flow, if messages from the allowed domain or email address pass other checks in the filtering stack, the messages are delivered. For example, if a message passes email authentication checks, a message from an allowed sender email address are delivered.
• By default, allow entries for domains and email addresses are kept for 45 days after the filtering system determines that the entity is clean, and then the allow entry is removed. For all other values like 1 day, 7 days, 30 days, specific date the allow entry expire at the defined date. By default, allow entries for spoofed senders never expire.
• For messages that were incorrectly blocked by domain or user impersonation protection, the allow entry for the domain or sender is not created in the Tenant Allow/Block List. Instead, the domain or sender is added to the Trusted senders and domains section in the anti-phishing policy that detected the message.
• When you override the verdict in the spoof intelligence insight, the spoofed sender becomes a manual allow or block entry that only appears on the Spoofed senders on the Tenant Allow/Block Lists page at https://security.microsoft.com/tenantAllowBlockList?viewid=SpoofItem.

• When the file is encountered again during mail flow, Safe Attachments detonation or file reputation checks and all other file-based filters are overridden. If the filtering system determines that all other entities in the email message are clean, the message are delivered.
• During selection, all file-based filters, including Safe Attachments detonation or file reputation checks are overridden, allowing user access to the file.

Report good URLs to Microsoft

For URLs reported as false positives, we allow subsequent messages that contain variations of the original URL. For example, you use the Submissions page to report the incorrectly blocked URL www.contoso.com/abc. If your organization later receives a message that contains the URL (for example but not limited to: www.contoso.com/abc, www.contoso.com/abc?id=1, www.contoso.com/abc/def/gty/uyt?id=5, or www.contoso.com/abc/whatever), the message won't be blocked based on the URL. In other words, you don't need to report multiple variations of the same URL as good to Microsoft.
