Tutorial / Cram Notes
Before deploying Microsoft 365 or implementing Azure AD Connect, it’s essential to clean up Active Directory to avoid synchronization issues. Synchronization problems can manifest as duplicate identities, invalid attributes, or other inconsistencies that disrupt service functionality and user experience.
IdFix is designed to help IT administrators:
- Detect and remediate identity objects and their attributes in Active Directory.
- Prepare for directory synchronization by identifying and resolving issues with objects such as users, groups, and contacts.
- Facilitate the updating of AD objects in bulk, saving time and reducing manual effort.
Running IdFix
To prepare for synchronization using IdFix, you should follow these general steps:
- Download and Run IdFix: Obtain the latest version from the Microsoft Download Center and run it within your environment.
- Analysis: IdFix will scan your AD and flag potential errors, such as duplicates or formatting issues that don’t comply with Azure AD requirements.
- Review results: After the scan, review the findings to understand the type of issues detected. Common problems include:
- Duplicates: Identical entries in two or more attributes that should be unique.
- Invalid formats: Entries that do not conform to the expected attribute format.
- Uniqueness violations: When an attribute that should be unique across all objects in AD isn’t.
- Fixes: Apply the recommended actions provided by IdFix to correct errors. You can either:
- Perform a manual update for individual objects.
- Use the bulk-editing feature to fix multiple issues at once.
Common Errors and Recommendations
| Issue Type | Description | Recommended Action |
|---|---|---|
| Duplicates | Two users have the same email address. | Resolve conflicts by renaming or removing the duplicate. |
| Invalid Formats | An email address doesn’t contain a valid format, such as user@domain.com. | Correct the format to meet Azure AD requirements. |
| Uniqueness Violations | A user’s ProxyAddress conflicts with another object. | Ensure that proxies are unique across all objects. |
Important Considerations
Before using IdFix, there are important considerations to keep in mind:
- Backup: Always back up AD before making changes. If a mistake occurs, you will have a recovery point.
- Permissions: The account running IdFix needs to have appropriate permissions to make the necessary changes in AD.
- Limitations: While IdFix is a powerful tool, it doesn’t cover every possible scenario. Some manual review and adjustments might still be required.
- Privacy: Be aware of privacy concerns when reviewing and modifying personal user data.
Conclusion
By utilizing IdFix as part of your preparation for identity synchronization, you can ensure a more reliable and error-free integration between your on-premises Active Directory and Azure Active Directory. It can significantly reduce the administrative burden of resolving identity issues post synchronization and support a more streamlined migration to Microsoft 365 services.
Practice Test with Explanation
True or False: The primary purpose of using IdFix is to identify errors such as duplicates and formatting issues in Active Directory before synchronization with Azure AD.
- A) True
- B) False
Answer: A) True
Explanation: IdFix is used to identify and remediate errors in Active Directory, such as duplicates and formatting issues, before syncing with Azure AD to ensure a smooth synchronization process.
Which of the following issues can IdFix help identify? (Choose all that apply)
- A) Syntax errors in directory objects
- B) Security vulnerabilities
- C) Duplicate attributes
- D) Expired user passwords
Answer: A) Syntax errors in directory objects, C) Duplicate attributes

Prior to running IdFix, you should?
- A) Disable directory synchronization
- B) Have administrative privileges on the local domain
- C) Ensure all user accounts are disabled
- D) Update all user passwords
Answer: B) Have administrative privileges on the local domain
Explanation: You need administrative privileges on the local domain to run IdFix and make the necessary changes to the directory objects.
True or False: After remediation, IdFix automatically applies the fixes to the directory objects.
- A) True
- B) False
Answer: B) False
Explanation: IdFix suggests fixes for identified directory objects issues, but it does not automatically apply these fixes. The administrator must review and apply the recommended changes manually.
What does IdFix use to perform its analysis of directory objects’ attributes?
- A) Azure AD Graph API
- B) Active Directory Domain Services (AD DS)
- C) Microsoft 365 compliance center
- D) PowerShell cmdlets
Answer: B) Active Directory Domain Services (AD DS)
Explanation: IdFix interacts with Active Directory Domain Services to perform its analysis of directory objects’ attributes.
True or False: IdFix requires an internet connection to perform its directory synchronization error identification.
- A) True
- B) False
Answer: B) False
Explanation: IdFix operates on the local domain environment to identify errors before synchronization. It does not require an internet connection to perform this analysis.
Which version of the .NET Framework is required to run IdFix?
- A) .NET Framework 0
- B) .NET Framework 5
- C) .NET Framework 5
- D) .NET Framework 7
Answer: C) .NET Framework 5
Explanation: IdFix requires .NET Framework 5 or newer to run.
True or False: IdFix supports remediation for multiple domains within the same forest simultaneously.
- A) True
- B) False
Answer: B) False
Explanation: IdFix is designed to work with one domain at a time. It does not support remediation for multiple domains within the same forest simultaneously.
Which attribute must be unique for each user in the directory?
- A) displayName
- B) userPrincipalName
- C) cn (Common Name)
- D) givenName
Answer: B) userPrincipalName
Explanation: The userPrincipalName (UPN) must be unique for each user as it is used as the login name within Azure AD and other services.
True or False: You should run IdFix on a domain controller.
- A) True
- B) False
Answer: B) False
Explanation: It is not recommended to run IdFix directly on a domain controller. It should be run from a separate administration workstation.
What type of action does IdFix suggest for most directory synchronization errors it identifies?
- A) DELETE
- B) UPDATE
- C) CLEAR
- D) CONTACT SUPPORT
Answer: B) UPDATE
Explanation: For most synchronization errors, IdFix will suggest an UPDATE action, which involves making corrections to the attribute value as recommended by the tool.
