Solved: Troubleshooting Guide for Error 0x80042707

Error Code 0x80042707 Summary

The error code 0x80042707 is typically encountered when working with Microsoft Outlook or Exchange Server, particularly in scenarios involving Active Directory or email configurations. This issue often arises due to permissions problems, misconfigured profiles, or issues with the user account and its attributes within Active Directory. The resolution of this error usually involves troubleshooting profile settings, checking for correct permissions on server-side resources, and ensuring that the necessary registry keys are properly set up on a client computer running Outlook.

Description of Error 0x80042707 and Where It Might Occur

This error can occur in several situations related to Microsoft Outlook or Exchange Server environments:

1. User Profile Issues: When an Outlook profile is improperly configured or corrupted, it may cause this error. This includes incorrect email settings, server details misconfigured, or the lack of necessary permissions for accessing resources like mailboxes and calendars.

2. Active Directory Permissions: A user account might lack the appropriate permissions to access required Active Directory objects such as Distribution Groups or Mailbox Rights. Ensuring that the user has all necessary rights is crucial, especially in large organizations where resource access control is strict.

3. Email Configuration Errors: Incorrect email configuration can lead to this error, including issues with Autodiscover service settings which are essential for automatically configuring Outlook clients. The Autodiscover URL or settings might be incorrect or unreachable due to network restrictions or misconfigurations.

4. Client Registry Settings Problems: Malformed or missing registry keys on the client machine can also result in this error, particularly if Outlook is trying to reference non-existent configuration values or paths that are outdated or incorrectly specified.

5. Outlook Add-ins and Third-party Software Interference: Occasionally, third-party software installed alongside Outlook or add-ins within Outlook might interfere with the application’s ability to connect properly to Exchange Server, causing this error due to conflicts in configuration settings or API usage.

Howto solve error code 0x80042707

To resolve the 0x80042707 error, follow these steps:

1.

  • Delete and Re-create Outlook Profile: Go to Control Panel > Mail, then select Show Profiles. Remove any problematic profiles and restart Outlook; it should prompt you to create a new profile.
  • 2.

  • Verify Exchange Server Settings: Ensure that the Autodiscover service is correctly configured and accessible. Test connectivity from your client machine by pinging the Exchange server or running an nslookup command for the relevant domain names (e.g., autodiscover.domain.com).
  • 3.

  • Check Active Directory Permissions: Confirm that the user account has adequate permissions to access necessary resources on the Exchange Server and within the Active Directory environment.
  • 4.

  • Review Client-side Registry Keys: Use regedit to inspect relevant Outlook client registry keys (e.g., HKEY_CURRENT_USER\Software\Microsoft\Office\x.x\Outlook\Profiles). Ensure no conflicting entries exist, especially those related to network paths or server names.
  • 5.

  • Run Outlook Repair and Scanpst.exe: If the profile deletion does not resolve the issue, consider running Outlook’s repair utility (scanpsts.exe) against any problematic PST files to fix corruption issues within them.
  • 6.

  • Disable Third-party Software/Outlook Add-ins: Temporarily disable all third-party software and add-ins that may be conflicting with Outlook’s operation; re-enable one by one to identify the culprit if necessary.
  • 7.

  • Contact System Administrator or Support Team: If none of these steps resolve the error, escalate the issue to your organization’s IT support team for further investigation and resolution specific to your environment.
