Microsoft writes the first letter. You write the second. The second letter is the first piece of paper in the engagement that is fully under your control, and across 47 formal compliance reviews it has done more to set the closing exposure than any other single document. Short, contractual, and signed by a senior officer. This is the structure we use.
Microsoft writes the opening letter. You write the second letter. The second letter is the first piece of paper in the engagement that is fully under your control, and it sets the tone, scope, and tempo for everything that follows. This page is the structure we use, the language we recommend, and the lines we never include.
The reply is short by design. Short is contractual. Long is conversational, and the auditor will read warmth as concession. Each paragraph has a specific job. Anything outside these seven jobs belongs in later correspondence or not at all.
What you leave out matters more than what you include. The omissions tell Microsoft that the buyer side is reading the contract, not the letter. Every item in this list is something we see in client drafts that has to come out before the reply goes.
Inside the Microsoft compliance organization and inside any third party auditor, your reply gets routed, summarized, and circulated. The summary is what most decision makers read. A reply written in the buyer side voice changes the summary, and the summary changes the engagement.
Third party audit teams handle hundreds of these engagements per year. Their internal triage sorts replies into managed, contested, and escalated tracks before the first data request goes out. A neutral, contractual reply lands in managed, which is the buyer friendly track. Apologetic or hostile replies trigger escalated, which is the opposite.
Microsoft compliance reports up to the same senior leadership that approves commercial concessions. A reply that signals the buyer treats the audit as part of a continuous commercial relationship rather than an adversarial event keeps Microsoft commercial open. Commercial open is leverage.
The reply also signals to internal and external legal counsel whether the engagement is being handled under privilege from day one. Where the reply is drafted under attorney work product, downstream auditor requests can be challenged on production grounds that a non privileged process cannot reach.
The template below is the structure we use across audit response engagements. Specific language is tuned per client and per agreement. The order is rarely changed because each paragraph closes off a specific avenue of auditor pressure before the next paragraph opens.
Open with a single sentence acknowledging receipt of the notice with the date Microsoft sent it and the date you received it. Mismatched dates matter because the response window often runs from the wrong date in the letter. Confirm the specific contract instrument under which Microsoft asserts its verification right, by name and effective date. This forces the engagement onto the actual contract, not a generic one.
Designate a single named contact, with title and direct contact details, as the channel for all correspondence. Note that other personnel will not respond to direct outreach and that auditor requests outside this channel will not be actioned. This single line eliminates a category of accidental concession.
Reserve rights expressly with respect to scope, timing, and the identity of the proposed third party auditor. The reservation language is the difference between negotiating from a position and conceding from one. Request a confidentiality framework, including scope of permissible use of data, retention period, and destruction at engagement end. Most third party auditors will accept this. Sending it first matters because the framework you propose becomes the starting point.
State that timeline commitments will follow internal contract review. Avoid committing to any specific date in the first reply. Sign from a senior named officer. Procurement, legal, or CIO level. The seniority of the signature anchors the engagement at a commercial level rather than an operational one.
Most clients have a first draft of the reply in hand before we are engaged. The draft is almost always written by IT operations and almost always overcommits. These are the three errors we strip out before any reply goes back to Microsoft.
Operations writes paragraphs explaining the estate, the recent reorg, the migration in flight, the upcoming consolidation. None of this is required. All of it becomes evidence in the auditor finding log. Volunteered context narrows your defenses later.
IT often offers to provide specific scripts, exports, or reports because the auditor named them. The contract rarely names them, and the format you commit to in the first reply is the format the auditor will hold you to. Format is negotiable later. Conceding it in week one is expensive.
The reply often thanks Microsoft for proposing Deloitte, KPMG, BDO, or another firm. Thanking is accepting. Acceptance closes off the right to object based on prior engagements, conflicts, or non disclosure constraints that the proposed firm may not satisfy in your industry.
For active audit notices, we draft the reply under attorney work product, route through procurement and legal, send under the named officer signature, and open the engagement clock from the date of acknowledgement rather than the date of receipt. The full audit defense engagement runs from there.
Across 47 formal compliance reviews, the reply is the single highest leverage document in the engagement on a dollars per word basis. A reply done well sets up scope negotiation, data request defense, findings rebuttal, and the commercial close. A reply done poorly closes off each of those moves before they begin. Our audit defense practice produces an average 79 percent reduction in initial Microsoft exposure, and the reply is the first lever in that number.
Three questions we hear in the days after the reply has gone back. The answers below match the buyer side posture we recommend across the practice.
A senior named officer with procurement or legal authority. The seniority anchors the engagement at the commercial level rather than the operational level. Procurement directors, general counsel, and CIO level signatures all work. Operations leads, system administrators, and IT managers should not sign the reply because the signature itself shapes how the auditor team triages the response internally. Signature seniority signals the engagement is being run on the buyer side as a commercial matter, which is the framing that benefits the defense over the next twelve weeks.
Within the notice window the contract requires, not the window the letter implies. Most enterprise contracts allow 15 to 30 days for acknowledgement. The letter often suggests a shorter window. Replying inside the contract window but not at the auditor pace is itself a posture signal. We typically send the reply at the back end of the acknowledgement window after internal review is complete, because acknowledging on day three reads as compliance and acknowledging on day twenty reads as deliberation.
Microsoft and the auditor will follow up with clarification requests. That is acceptable. Clarification is negotiation. A short reply that triggers follow up exchanges is preferable to a long reply that volunteers detail. The follow up exchanges become opportunities to introduce additional reservations, additional scope questions, and additional posture without those points being seen as escalation. Most buyer side defenses are built across multiple short exchanges, not a single long opening statement.
