Your Administrator has blocked your ability to open this file type in OneNote.

Dear @Edwards, Christopher,

Thank you for reaching out to the Microsoft Q&A Community.

I understand this is an urgent issue for you. The message indicates that a policy set by your organization's IT administrator is preventing you from opening certain file types within OneNote.

This is not an issue that can be resolved by an individual user, as it stems from an administrative policy.

Organizations often implement security policies to protect their networks and data from potential threats. Certain file types (like executables, scripts, or sometimes even specific document types) might be deemed high-risk and are blocked from being opened directly within applications like OneNote. This is a common security measure to prevent malware or unauthorized content from being executed or accessed.

The message explicitly states that your "Administrator has blocked" this. Therefore, the only way to get this resolved is to contact your organization's IT support, help desk, or the person who manages your Microsoft 365 environment.

• Explain the situation: Clearly state the exact error message you're receiving ("Your Administrator has blocked your ability to open this file type in OneNote").
• Specify the file type: Tell them what type of file you are trying to open (e.g., a .PDF, .DOCX, .XLSX, .EXE, .ZIP, etc.). Knowing the specific file type is crucial for them to understand the policy.
• Explain why you need to open it: Provide context on why you need to access this particular file. They might be able to whitelist that specific file type for you, provide an alternative way to access it, or explain the security implications.
• Mention the urgency: Reiterate that you need a fix for this ASAP.

Your administrator would typically need to adjust security policies related to OneNote, SharePoint, or Microsoft 365 file access within their administrative portals (e.g., Microsoft 365 admin center, SharePoint admin center, or Microsoft Intune/Azure AD policies) to allow that specific file type.

As a forum moderator, I cannot bypass organizational security policies or grant you access to blocked file types. Only your organization's IT administrator has the authority and tools to modify these settings.

Please reach out to your IT department as quickly as possible.
