- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Attempting to send an encrypted email using Microsoft Outlook.
- Observed behavior
- Outlook displays an error message stating that the computer is not set up for Information Rights Management.
Ensure you have global administrator or Exchange administrator privileges in your Microsoft 365 tenant, as resolving this issue requires accessing the admin center and verifying organization-wide settings.
Verify Microsoft 365 Licensing and Tenant Configuration
Ensure the sending user has a supported license and that Information Rights Management is properly enabled for the tenant.
The Information Rights Management (IRM) feature requires specific licensing and tenant-level configurations. If these are missing or misconfigured, Outlook will block encrypted emails.
Sign in to the Microsoft 365 admin center, go to 'Users' > 'Active users', and verify that the affected user is assigned a license that supports IRM, such as Microsoft 365 Business Premium.
Access the Exchange admin center and ensure that Information Rights Management is enabled for your organization.
Review your Microsoft Purview compliance portal to ensure that Microsoft Purview Message Encryption is properly configured for the tenant.
Create a Microsoft Support Request
If licensing and tenant settings appear correct but the error persists, request assistance from Microsoft Support.

Frequently Asked Questions
What is Information Rights Management (IRM) in Outlook?
Information Rights Management (IRM) is a security feature in Microsoft 365 that allows senders to specify access permissions on email messages. It helps prevent unauthorized users from printing, forwarding, or copying sensitive information.
Which Microsoft 365 licenses include Information Rights Management?
IRM and message encryption are typically included in licenses such as Microsoft 365 Business Premium, Office 365 E3 and E5, and Microsoft 365 E3 and E5.
Can I fix the Outlook IRM error without administrator access?
No, resolving this error requires checking and modifying tenant-level settings and user licenses, which can only be done by a user with Microsoft 365 global or Exchange administrator privileges.
Why does Outlook state my computer is not set up for IRM?
This message typically appears when the Rights Management service is disabled in your organization's Microsoft 365 tenant, the Purview Message Encryption is misconfigured, or the user's account lacks the required license to utilize encryption features.
