MIP SDK cannot read file labels if a message was encrypted by Outlook Classic.
C++ application uses MIP SDK version 1.14.108. The application does Office files decryption and labels reading. The problem with labels reading is observed. Steps to reproduce: Create a docx file with a label which does not impose encryption. Open Outlook Classic, compose email, attach the document from 1, click Encrypt, send. During message sending our application intercepts encrypted by Outlook docx file in temporary folder C:\Users\UserName\AppData\Local\Temp Application decrypts the intercepted file using mipns::FileHandler::RemoveProtection. Visual inspection demonstrates that decryption runs successfully. Then a separate FileHandler for decrypted file is created, and mipns::FileHandler::GetLabel() returns an empty label. It means that the label was lost during decryption. Upon visual inspection of the decrypted file via Word we can see that the label is missing. Also, we do not see MSIP_Label* entries in meta data (File -> Info -> Properties -> Advanced Properties -> Custom).

Hi Security Experts, I’ve recently started exploring the Microsoft Graph Security API to centralize and automate security operations across different Microsoft 365 services. The idea is to build a single automation layer that can: Collect alerts from Defender for Endpoint, Defender for Cloud, and Identity Protection; Enrich them with context (user, device, and location data); And automatically push them to an external system like Jira, n8n, or a custom SOAR workflow. I was able to authenticate and list alerts using the endpoint: “GET https://graph.microsoft.com/v1.0/security/alerts” However, I’m still trying to understand the best practices for handling rate limits, pagination, and permissions — especially when integrating continuous polling or real-time ingestion into external tools. Has anyone here implemented Graph Security API automations in production? I’d love to hear about your experiences — specifically around performance, alert filtering, and authentication (App Registration vs Managed Identity). Thanks in advance, Luca
