Slack/email/badge exports fractured investigations; ServiceNow + Slack Discovery + Microsoft Purview unified case file

Overview

Internal investigations drew data from Slack, email, badge systems, and HR files, but there was no unified case file. Analysts saved exports to personal folders, legal holds were tracked in spreadsheets, and handoffs between HR, Security, and Legal restarted context. Intelligex implemented a case system that ingests Slack exports, email and file collections, badge logs, and HR data into a single workspace with role?based access and legal approval gates. Evidence carried chain?of?custody metadata, counsel signed off on scope changes, and publication to stakeholders followed a governed path—while Slack, Microsoft 365, the badge system, and HRIS stayed in place. Documentation became complete and consistent, and handoffs were fewer and faster.

Client Profile

• Industry: Technology and services with a global workforce
• Company size (range): Multi?region operations with centralized Legal & Compliance and distributed HR and Security teams
• Stage: Investigations initiated via email; Slack and email exports saved to shared drives; badge logs pulled ad hoc; HR data shared as PDFs; legal holds tracked in spreadsheets; case notes lived in documents
• Department owner: Legal & Compliance (Employment, Ethics & Compliance, and Legal Operations)
• Other stakeholders: HR/Employee Relations, Security/Physical Access, IT/Identity, Privacy, Internal Audit, Executive Sponsors

The Challenge

Each investigation created a new workflow from scratch. HR opened a ticket and emailed Legal, Security pulled badge logs on request, and IT exported mailboxes when time allowed. Slack data was exported separately, often by different people and on different days, so timelines had gaps. Case documents were stored in folders named by investigator, not by matter, and there was no reliable place to see what was collected, from whom, and when.

Scope control and access were inconsistent. Legal holds were announced by email, custodians were tracked in a spreadsheet, and there was no visible link between a hold and the collected materials. Investigators shared draft summaries with broad distribution lists, and case notes commingled confidential allegations with administrative details. When a matter expanded to include new custodians, teams duplicated work because earlier decisions and collections were buried in threads.

Auditability lagged. Evidence arrived as ZIP files without consistent hash or source metadata, exports used different time zones and formats, and redactions were applied in inconsistent ways. When Internal Audit or external counsel asked for a complete record, investigators reconstructed the story across emails, exports, and personal notes instead of producing a single, defensible case file.

Why It Was Happening

Processes were tool?centric rather than case?centric. Slack, email, and file systems offered export and eDiscovery features, but there was no case system stitching them together with a common taxonomy, chain?of?custody, and permissions model. Evidence lived where it was created, not where it would be reviewed.

Roles and approvals were informal. Investigators relied on judgment to determine who could view what, and Legal reviewed sensitive decisions late. Without role?based access and approval gates, privileged analysis mixed with operational notes, and expansions of scope lacked recorded rationale tied to the case.

The Solution

Intelligex implemented a case management workflow that centralizes intake, collections, and review in one permissioned workspace. Slack exports, Microsoft 365 eDiscovery collections, badge logs, and HR data flowed into a standardized evidence library with chain?of?custody and hash capture. Legal approved scope changes and redaction strategies in?flow, and publication to stakeholders followed a governed template. The design used Slack’s discovery capabilities (for example, the Slack Discovery API) and Microsoft 365 eDiscovery collection (Microsoft Purview eDiscovery), and enforced role?based permissions aligned to NIST RBAC. Documentation practices followed defensibility principles recognized in eDiscovery frameworks such as The Sedona Principles.

• Integrations: Slack discovery/export; Microsoft 365 eDiscovery for Exchange, OneDrive, and SharePoint; identity provider for custodian mapping; physical access/badge system feeds; HRIS for role, manager, and employment status; case system (for example, ServiceNow or Salesforce) for workflow, notes, and evidence storage.
• Case intake and triage: Standardized forms to capture allegation, scope, custodians, and urgency; legal hold issuance with confirmation tracking; automated custodian mapping to identity and HR records.
• Collections and evidence: Connectors to ingest Slack conversations, email, files, badge logs, and HR extracts; normalization to a common time zone and format; chain?of?custody metadata and hashes; deduplication and threading for communications.
• Permissions and privilege: Role?based access to evidence, with counsel?only fields for privileged analysis; segregation of administrative notes; redaction profiles for sensitive identifiers and third?party data.
• Review and approvals: Legal approval gates for scope changes, new custodians, and publishing summaries; reason?coded decisions with citations to policy; maker?checker for high?risk matters.
• Timelines and reporting: Auto?generated event timelines from collected data; dashboards for matter status, collection progress, and outstanding holds; exportable packets with intake, collections, notes, approvals, and publication record.
• Security and privacy: Least?privilege defaults; minimal personal data in notifications; immutable logs of access and changes; retention aligned to records schedules and legal hold requirements.

Implementation

• Discovery: Mapped current investigation types and handoffs; inventoried Slack, email, file, badge, and HR sources; sampled recent matters for gaps in chain?of?custody and access; gathered Legal, HR, Security, Privacy, and Audit requirements for evidence handling and approvals.
• Design: Authored the case taxonomy and intake forms; defined custodian mapping and legal hold process; designed connectors and normalization rules for Slack and Microsoft 365 collections; set role?based permissions, counsel?only fields, and redaction profiles; planned approval gates and reason codes; outlined dashboards and export formats; established change control.
• Build: Configured the case system with intake, queues, and evidence library; integrated Slack discovery/export and Microsoft Purview eDiscovery; connected badge logs and HRIS feeds; enabled chain?of?custody capture and hashing; implemented approval workflows and counsel?only notes; instrumented logs, retention, and access controls.
• Testing/QA: Ran in shadow mode on active matters; validated evidence ingestion, time alignment, and deduplication; exercised legal hold confirmations; tested role?based access and redaction profiles; piloted with HR and Security on a mixed set of cases; tuned forms, thresholds, and messages from reviewer feedback.
• Rollout: Launched intake and evidence library for new matters; migrated open cases into the system with supervised backfill of key artifacts; enabled approval gates and publication templates; retired spreadsheet trackers and ad hoc folders after stable cycles.
• Training/hand?off: Delivered quick guides for investigators on intake, collections, and timelines; trained Legal on approval queues and counsel?only notes; briefed HR and Security on role?based access and redaction; updated SOPs and escalation playbooks; transferred ownership of templates, connectors, and dashboards to Legal Ops under change control.
• Human?in?the?loop review: Established recurring reviews of redaction accuracy, scope changes, and access exceptions; recorded decisions with rationale and effective dates; updated workflows, profiles, and permissions accordingly.

Results

Investigations moved through a single, governed path. Intake captured scope and custodians, collections flowed automatically from Slack, Microsoft 365, badge, and HR sources, and evidence landed in a permissioned case file with chain?of?custody. Legal approved scope changes in the system with recorded rationale, and publication to stakeholders used a standard template.

Documentation became complete and defensible. Timelines showed what happened and when, redactions were applied consistently, and exportable packets included intake details, legal hold confirmations, collections with hashes, review notes, and approvals. Handoffs between HR, Security, and Legal no longer restarted context, and teams spent more time on analysis than on assembling artifacts.

FAQ

What tools did this integrate with? The case system connected to Slack discovery and export capabilities (for example, the Slack Discovery API), collected email and files via Microsoft Purview eDiscovery, ingested badge logs from the physical access system, and enriched context with HRIS data. Workflow and evidence lived in a case platform such as ServiceNow or Salesforce, and access followed NIST RBAC principles.

How did you handle quality control and governance? Case templates, approval gates, and redaction profiles lived under Legal Ops change control with owners and effective dates. Every hold, collection, access, edit, and approval wrote to immutable logs. Maker?checker applied to high?risk matters and publication of sensitive summaries. Chain?of?custody and hashes accompanied each artifact, and dashboards surfaced exceptions for review.

How did you roll this out without disruption? The system ran in shadow mode on live matters to validate collections and permissions. New investigations used the case intake first, followed by automated collections and approval gates. Open cases migrated gradually with supervised backfill of key evidence. Spreadsheets and shared folders were retained read?only as a fallback until cycles stabilized.

How were legal holds and custodians managed? Holds were issued from the case, with custodian mapping to identity and HR records. Confirmations and reminders were tracked automatically, and collected materials linked to the hold record. Adding or removing custodians required legal approval with recorded rationale.

How did you protect privacy and privilege? Role?based access restricted who could view specific evidence and notes. Counsel?only fields stored privileged analysis, and notifications carried minimal detail with links back to the case. All access and exports were logged, retention followed records policy, and legal holds overrode standard disposition where applicable.

What about large Slack and email collections? Connectors performed threading and deduplication, normalized time zones, and captured hashes for each item. Batch collections were scheduled when needed, and incremental updates refreshed timelines as new messages arrived.

Can this support external counsel or auditors? Yes. External users received scoped access or export packets containing intake, collections with chain?of?custody, timelines, notes, and approvals. Access was time?boxed and logged, and privileged content remained restricted.
