Don't have a package yet?
Run Collect-IntuneDiagnostics.ps1 in an
elevated PowerShell on the device. It collects MDM logs,
event logs, registry exports, identity/network info and the IME logs, and
writes IntuneDiag-<device>-<timestamp>.zip to
C:\Temp. Upload that zip above.

.SYNOPSIS
Collects a complete diagnostics package from an Intune-managed Windows device.
.DESCRIPTION
Mimics the Intune "Collect diagnostics" action and extends it with:
- MDM logs via mdmdiagnosticstool.exe (all registered areas)
- Relevant Event Logs (MDM, Entra/AAD, Device Registration, ESP/Shell-Core)
- Registry exports (Enrollments, PolicyManager, IME, Autopilot, GPO policies)
- Identity status (dsregcmd, machine AND interactive-user context), certificates, network info
- Intune Management Extension (IME) logs
- Defender support files, Windows Update logs, system reports
- Co-management, Defender for Endpoint onboarding, Delivery Optimization state
- Disk space, time sync, TPM status
- Status of relevant services and scheduled tasks
Result: a single zip file in C:\Temp (or a custom path), plus a
_MANIFEST.json describing the run (version, profile, per-step outcome).
.PARAMETER OutputPath
Folder where the zip file will be created. Default: C:\Temp
.PARAMETER Remote
Slim profile for unattended/Intune use: skips the slow and large sections
(msinfo32, Get-WindowsUpdateLog, Defender -GetFiles cab, full-range event
log export, full mdmdiagnosticstool area zip) so the run stays well under
the Intune script timeout and the Sherlog upload size limit, while keeping
the IME logs, event logs (last 14 days), registry, identity and network data.
.PARAMETER UploadUrl
When set, the resulting zip is uploaded to this Sherlog drop-off endpoint,
e.g. https://sherlog.nl/api/diagnostics . Requires -UploadToken. Must be
https:// - a plain http:// URL is refused so the token is never sent in
cleartext.
.PARAMETER UploadToken
The self-chosen secret the admin generated on the Sherlog /inbox page. It
authorizes the upload and is the key to view the uploads at /inbox. It is
always redacted from every collected text file (including the transcript,
which PowerShell stamps with the full command line it was invoked with),
regardless of -Anonymize.
With -UploadUrl and -UploadToken set, the script also pings
<base>/api/collect-status at the start of the run and again if it knows the
run failed, so the inbox can show the device as "collecting" instead of
staying empty for the minutes the collection takes. The ping carries only
the phase, the profile, the collector version and the same (optionally
anonymized) device label as the upload - never log content.
.PARAMETER MaxUploadMB
Client-side size guard matched against the server's MAX_UPLOAD_MB (default
100). A package over this size is not uploaded (it would be rejected with
413 anyway); the local zip is kept.
.PARAMETER Proxy
Explicit proxy URL for the upload (e.g. http://proxy.contoso.com:8080). If
omitted, the script tries to auto-detect one from `netsh winhttp show
proxy`, since a SYSTEM-context run has no per-user WinINET proxy settings
and would otherwise fail on any proxy-only network.
.PARAMETER Anonymize
Best-effort redaction of tenant and company data from the package: tenant id,
tenant/company name, domain(s), UPN/e-mail, device name and user name are
replaced with placeholders in all TEXT files, and the zip name + upload device
name are anonymized. Well-known system principals (SYSTEM, NT AUTHORITY, ...)
are never redacted, since doing so would corrupt registry paths like
HKEY_LOCAL_MACHINE\SYSTEM\... and break Sherlog's SYSTEM-context detection.
This is best-effort, NOT a guarantee: binary files (event logs .evtx, Defender
.cab, the nested mdmdiag .zip) are NOT scrubbed and may still contain
identifiers - review the package before sharing.
