The Phishing Reporter Page View feature fails due to Microsoft's deprecation of legacy Exchange Online tokens earlier than expected date, June 2025.
Microsoft 365 users utilizing the Phishing Reporter Page View feature.
If you are using the Phishing Reporter Page View version, it may fail with the following empty message:
Microsoft has deprecated legacy Exchange Online tokens, which the Phishing Reporter previously relied upon for authentication and access.
Customers can turn on legacy Exchange Online tokens following below documentation.

It can take up to 24 hours before all requests from Outlook add-ins for legacy tokens are allowed.
A more permanent solution, we highly recommend using Microsoft Ribbon Phishing Reporter that utilises Graph API and no dependency on Exchange Online tokens.
