Microsoft 365 Governance

An MSP checklist for reviewing Microsoft 365 external sharing across customer tenants with explicit coverage, isolation, risk, and remediation guardrails.

A Microsoft 365 external-sharing review is most effective as a repeatable operating process: define scope, observe access, prioritize decisions, remediate carefully, and preserve evidence. Phase 1: define the review Choose the tenant, SharePoint sites, OneDrive accounts, period, owners, and risk questions. Decide whether the review covers link-based permissions only or also direct guest access and…

Anyone and Specific people links solve different collaboration problems. Their main difference is not the color of the sharing dialog—it is how access is associated with identity. Anyone links An Anyone link does not require the recipient to authenticate. Anyone who obtains the URL can use it within the link’s role and expiration. It can…

External sharing is an essential Microsoft 365 capability. Good governance preserves collaboration while making access intentional, visible, reviewable, and proportionate. Common risk patterns Anyone links that can be forwarded without authentication. Edit access where view access would be enough. Links without expiration. Shared folders whose contents keep changing. Guests or recipients whose business relationship ended….

Disabling or deleting an employee account does not reduce every Microsoft 365 sharing scenario to one outcome. Link type, resource location, ownership, retention, guest identity, and tenant policy all matter. Separate access by the employee from links they created Removing the employee’s sign-in access addresses their account. It does not automatically prove that every sharing…

Understand the policy relationship The OneDrive organization-level sharing setting cannot be more permissive than SharePoint. Review both settings, along with default link type, link permission, Anyone-link expiration, guest controls, and domain restrictions. Monitor active sharing—not…

A reliable review separates these mechanisms instead of treating them as one flag. Begin with known content For a specific file or folder, open Manage Access. Review links, direct access, and inheritance. Confirm whether external people must…

Define scope and evidence date Record the tenants, sites, OneDrive accounts, libraries, and time window included. Identify exclusions and failed scans. An audit that cannot explain its coverage should not present absence…
