Administers the email, chat, meeting and file-sharing platform the organization runs on — tenant and domain configuration, mail authentication and routing, phishing and spam controls, shared mailboxes and distribution groups, external sharing and guest access, permission sprawl in file storage, and retention and legal hold. Use this to configure a tenant, tighten sharing, investigate a mail delivery or phishing problem, or work out who can see a file and why.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Collaboration platform administration This platform holds most of the organization's unstructured information and nearly all of its external communication. It is usually configured once during migration, by whoever ran the migration, and then never revisited. ## Get mail authentication right, and keep it right SPF, DKIM and DMARC together determine whether your mail is delivered and whether someone else can send as you. All three need to exist and agree. - **SPF** breaks quietly as third-party senders accumulate — marketing platforms, ticketing systems, invoicing tools — and has a hard limit on lookups that a growing list eventually crosses. - **DKIM** has to be enabled per sending domain and per service, not once for the tenant. - **DMARC** starts in monitoring and only protects once it moves to enforcement. A policy left at none for two years is a report nobody reads. Every new tool that sends mail on your behalf is a change to this configuration. Route that through the same process as any other change, or the first sign will be a customer saying your invoices go to spam. ## Phishing controls are configuration, not awareness training …

How to install
mdr add cbrock84/headcount/collaboration-platform-administration@sha256:d0a772dad8876909The line at the top of this page pins the label git:20260917.16ae2bd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
