Microsoft is investigating a newly identified issue that prevents users of the classic Outlook client from opening encrypted emails sent by other organizations.
The company confirmed the problem in a recently updated support document, noting that the bug affects customers across all Office release channels.
According to Microsoft, users attempting to access such emails may encounter the error message: “Configuring your computer for Information Rights Management.” The glitch impacts OMEv2 (Office Message Encryption version 2) messages when sent across different tenants, creating disruptions for enterprise communication.
Temporary workaround provided
While the root cause is still under review, Microsoft has issued a temporary fix. Impacted organizations can either exclude external users from Conditional Access policies or enable cross-tenant settings that allow authentication tokens to be trusted between Entra tenants.
The company recommends the second option as the simpler solution. Administrators can enable cross-tenant access by navigating to the “Inbound access settings – Default settings” page in the Microsoft Entra admin center, selecting “Trust settings,” and then enabling “Trust multifactor authentication from Microsoft Entra tenants.”
