Your Archive Migration Is Also an AI Governance Decision
When most compliance officers and general counsel think about AI governance, they reach for a policy document. Who can use which tools, what data can be shared, how outputs should be reviewed. That work matters. But there is a more fundamental question underneath it that most companies have not answered honestly, and until they do, the governance picture has significant gaps in it regardless of what the policy says.
Do you know where all your data is? And do you know what your people are saying to AI tools right now?
For most enterprises in regulated industries, the honest answer to both is no. The consequences of that are no longer theoretical.
The regulatory precedent that changes everything
Before we get to AI, it is worth understanding what regulators have already demonstrated they will do when business communications go ungoverned.
In January 2025, the SEC charged twelve financial firms with recordkeeping failures and issued combined penalties of more than $63 million. The core failure in every case was the same: business communications were happening in channels that were not captured, preserved or auditable. Employees used personal email, WhatsApp, iMessage. The records regulators expected to find simply did not exist. Since 2021, more than 100 firms have been fined over $2 billion for recordkeeping violations in this category alone. These were not small or careless firms. They included some of the largest names in financial services, with compliance functions, legal teams and governance frameworks already in place. The frameworks existed. The visibility did not.
Now apply that logic to AI. Your employees are using ChatGPT, Microsoft Copilot, Google Gemini and other tools to draft communications, analyze data, summarize documents and make recommendations. Some of those interactions involve client information, commercially sensitive data, regulated content. You cannot see them. You cannot audit them. If a regulator asks for evidence of what your people discussed with an AI tool in connection with a particular transaction or decision, you have nothing to show.
That is the same problem the SEC was fining firms for, applied to a channel that is growing faster than any previous one. The question for every GC and CCO in a regulated business is not whether this scrutiny is coming. It is whether you will be ready when it does.
The AI your organisation just deployed is only as trustworthy as your data
The ungoverned communications problem is one half of this. The other half lives inside Microsoft 365 itself, and it connects directly to the archive.
Microsoft 365 Copilot is rolling out across enterprises at pace. The productivity case is real. But Copilot does not generate answers from nothing. It grounds its responses in the data your company holds inside Microsoft 365, surfacing whatever it can access based on existing permissions. That creates two distinct risks that most compliance and legal teams have not fully accounted for.
The first is oversharing. Copilot can surface content that technically falls within a user’s permissions but that no reasonable person would expect them to see: HR files, financial data, sensitive legal correspondence. According to Gartner’s January 2025 survey of IT leaders, 64% reported that information governance and security risks required significant time and resources to deal with, and 40% delayed their Copilot rollouts by three months or more specifically because of data oversharing concerns. A separate Gartner finding shows that nearly half of IT leaders have little or no confidence in their ability to manage Copilot’s security and access risks. The data estate is not clean enough to trust the AI operating across it, and the people responsible for deploying it know it.
The second risk is incompleteness, and this is where the archive becomes central to a governance conversation. If your email archive still sits in Enterprise Vault, Dell EMC SourceOne or another legacy platform outside Microsoft 365, Copilot cannot see it. Years of institutional knowledge, client history, compliance records and business decisions are invisible to the tool your leadership team just invested in. When Copilot summarizes a client relationship or surfaces context ahead of a negotiation, it is working from a partial picture and presenting it as though it were complete. For a GC advising on a dispute, or a CCO preparing for a regulatory examination, the gap between what Copilot shows and what the record actually contains is not just a productivity problem. It is a liability.
Why the archive is the governance gap nobody has closed
The email archive tends to sit at the edge of the IT estate, noticed mainly when someone needs to retrieve a record for a legal hold or regulatory request. But what it actually contains is among the most sensitive, compliance-critical data in most companies. Journal archives, in particular, capture communications that were archived precisely because regulators require it. This is not peripheral data. It is the record of how your company operated, communicated and made decisions over years.
When that archive remains in a legacy platform, outside the governed Microsoft 365 environment, the consequences are practical and immediate. Retention policies do not apply to it. eDiscovery tools cannot reach all of it. AI cannot ground itself in it. And when a regulator or legal team asks for a specific set of records, the answer “some of that data is in a system we haven’t fully migrated yet” is not one that holds up under scrutiny.
Getting the archive into Microsoft 365 properly changes all of that. It becomes governed data: auditable, searchable, subject to retention policies, visible to Copilot and defensible if challenged. The migration stops being a technical housekeeping task and becomes what it always should have been treated as: a governance act with direct implications for legal, compliance and risk.

Closing both gaps at the same time
This is where having the right combination of capabilities matters, because the two problems described here require two distinct tools working together.
Transvault Intelligent Migrator moves enterprise email archives into Microsoft 365 compliantly, with full chain of custody maintained throughout, metadata preserved and compliance integrity intact. Over 3,500 projects have been completed across 56 countries this way, at ingestion speeds exceeding 6.7TB per day. What arrives in Microsoft 365 is not just accessible but governable, auditable and ready for the AI layer operating across your estate.
Transvault Intelligent Ally addresses the other side of the problem. It captures AI interactions across leading generative AI platforms including ChatGPT, Microsoft Copilot, Claude and Google Gemini, attributes every interaction to a named user with full metadata, and retains that record on your own infrastructure. Every conversation your employees have with an AI tool becomes part of your auditable, governed record. The visibility that regulators have been demanding for electronic communications now extends to AI, before a regulator asks for it rather than after.
Together, these two capabilities address the full picture. The historical data that AI needs to be useful and trustworthy is brought into the governed estate. The new interactions your people are having with AI tools are captured, attributed and auditable from the moment they happen. The archive is governed. The AI activity is governed. The gap that the SEC has been fining firms for is closed before it opens.
The deadline that changes the calculation
The EU AI Act’s high-risk system obligations, originally due on 2 August 2026, have been pushed back following the Omnibus VII agreement reached in May 2026. Standalone systems now have until December 2027. Systems embedded into products have until August 2028. It requires companies to classify their AI systems, maintain logs, implement oversight and produce evidence on request. Fines for prohibited practices reach up to €35 million or 7% of global turnover. Fines for high-risk system failures reach up to €15 million or 3% of turnover. The Act applies extraterritorially: if your company sells into Europe, it applies regardless of where you are headquartered.
For GCs and CCOs who have watched the SEC’s recordkeeping enforcement program unfold over the past four years, the pattern here is familiar. A regulator identifies a category of risk. Firms that treated it seriously early are in a defensible position. Firms that did not face examination, enforcement and reputational cost. the EU AI Act is following the same trajectory, and December 2027 is closer than most companies’ project timelines allow for.
The archive and the AI interactions are both part of the answer. Getting both right, with the same rigor, is what genuine AI governance looks like in practice rather than on paper.
