A common request we see from leadership teams is straightforward on the surface: connect an AI assistant to the full Microsoft 365 environment — Outlook, calendar, SharePoint, OneDrive — and give it permission to send emails on an executive’s behalf. The rationale is usually productivity. In practice, this is a governance decision that deserves more scrutiny than it typically receives.
The most immediate risk isn’t whether the model can write a coherent message. It usually can. The risk is what happens when it writes a message that is slightly wrong: a misstated figure, a client name used incorrectly, a confidential detail shared with the wrong recipient. When that message is sent by a senior leader — or appears to be — the reputational exposure is real and difficult to reverse.
There is also a pattern worth watching: permission creep. What begins as read-only calendar access tends to expand over time into send-on-behalf permissions, then automated replies, then broader delegation across systems. Without an explicit boundary defined at the start, access rarely shrinks. It accumulates.
Connecting AI to SharePoint and OneDrive introduces a second layer of exposure. The assistant gains the ability to read documents, financial files, and internal communications that may not be appropriate for broad model access. Data governance becomes as important as communication governance.
A more controlled approach doesn’t require rejecting the request. It requires structuring it. Start with read-only access and internal drafting support. Keep external sends behind a human approval step. Define scope by role and communication type. Maintain a clear audit trail of what the assistant accessed and sent, and review that log periodically.
The organizations that handle AI integration well tend to treat the assistant as a governed actor inside their operational workflow — not as a trusted colleague and not as an autonomous agent. That distinction matters. It changes how permissions are granted, how outputs are reviewed, and how quickly access is allowed to expand.
AI connected to email and files is not inherently a bad decision. It becomes risky when send permissions are granted before the organization has defined what the assistant may send, to whom, and under what review. The sequencing should be deliberate: controls first, then access — and only as fast as those controls can be reliably enforced.
