Quiet concerns around enterprise AI use surfaced after a technical flaw exposed gaps in how automated tools handle sensitive data inside corporate systems.
Microsoft confirmed that a bug in the enterprise version of its Copilot AI tool allowed access to private user emails that were outside its approved scope. The issue was linked to Copilot’s email summarisation feature, which is meant to help enterprise users quickly review messages.
According to a technology news outlet, the AI tool began pulling content from folders such as Sent Items and Drafts. These folders were not intended to be included, effectively allowing the system to cross internal security boundaries. This triggered concern among organisations using the tool in controlled enterprise environments.
Microsoft acknowledged the issue and said a fix started rolling out earlier this month. The company did not reveal how many organisations were affected or whether any sensitive information was exposed during the time the bug was active. The lack of clarity has left some enterprise customers uneasy about oversight and risk management.
The incident adds to wider unease about the speed at which AI tools are being deployed in business settings. While companies are keen to use AI to improve productivity, privacy and compliance remain critical when such tools are connected to core systems like email servers.
The timing is challenging for Microsoft, which has invested heavily in embedding AI across its products. Copilot features are now integrated into Windows 11 PCs, enterprise software, and cloud services. However, adoption has faced hurdles, with reports suggesting AI-focused Windows 11 devices have not generated the expected market interest. In response, Microsoft is reportedly shifting its messaging from AI-first promotion to broader performance improvements.
The wider AI sector has also seen turbulence. Issues such as prompt injection attacks and the use of autonomous AI agents for handling financial or personal data have made enterprises more cautious. Other tech majors, including Google, have faced their own AI-related setbacks, while Apple’s slower and more measured AI rollout now appears less risky.
The Copilot episode highlights a familiar tension between rapid innovation and data security. As AI assistants become more deeply embedded in daily workflows, strong safeguards and testing become essential. Microsoft’s quick response may limit immediate damage, but the incident reinforces the need for privacy protection to keep pace with AI advancement.
