IdFix

IdFix 2.6.0.3, released by Microsoft Corporation, is a directory-hygiene utility designed for IT administrators who need to audit and remediate on-premises Active Directory objects before synchronizing them to Azure Active Directory. Operating in the identity-management category, the tool scans the local AD forest for user, group, and contact records whose display names, SMTP addresses, proxyAddresses, sAMAccountNames, or other directory attributes violate Azure AD naming and formatting rules. It then presents a sortable grid of detected issues—such as duplicate or invalid SMTP suffixes, illegal characters, or exceeding length limits—and allows the operator to fix the attributes in bulk or one by one directly within the same interface. Because changes are written back to Active Directory, the cleaned data flows seamlessly through Azure AD Connect during subsequent sync cycles, reducing the risk of failed exports or sync errors that could delay a cloud migration project. Typical use cases include enterprise tenants preparing for Office 365 onboarding, hybrid identity deployments, or periodic directory-health audits intended to keep the on-prem and cloud directories aligned. IdFix supports multi-domain forests, can target specific organizational units, and generates CSV logs for change tracking and rollback purposes. The single-version lineage (currently 2.6.0.3) is lightweight, requires no server-side components, and runs on any Windows workstation that has .NET Framework 4.5 and read access to the global catalog. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
