Responding to a Microsoft Audit Letter

The first response sets the tone for the whole audit. This guide gives you the exact moves for the first 30 days, the language to use, the data not to volunteer, and the way to keep the auditor inside the contract.

The first 30 days decide the rest

An audit letter is an opening move, not a verdict. How you answer in the first month shapes the scope, the timeline, and the auditor's assumptions about what you have. The goal of the first response is calm control, not speed and not volume.

What the guide covers

Do not accept the first report value. The auditor's draft compounds every gap and reads every ambiguity against you. It is the start of a negotiation, not the end of one. The Effective License Position is settled after the report, not before.

A worked first response

DayMove
1 to 3Acknowledge in writing, confirm the verification type, name a single point of contact
4 to 10Request scope and confidentiality terms, freeze internal narrative, brief leadership
11 to 20Begin your own ELP build with independent help, gather entitlement evidence
21 to 30Respond to the data request on your terms, hold the auditor to the contract

For hosters

If your letter concerns SPLA, the response is different. The lookback is 36 months, the auditor is a Big Four firm, and the defense is reconstructing your monthly reporting. Read the SPLA materials and speak to us directly.
