The error 'network access is denied' when trying to attach files from a local shared drive in OWA on IE8 can be frustrating for users. This issue affects individuals who are using Exchange Server with Outlook Web Access (OWA) and attempting to send emails that include attachments from a mapped local shared drive.
This problem can hinder productivity, as users may need to navigate through multiple drives or folders to find the required files. In this troubleshooting guide, we will walk you through possible causes and solutions to resolve the 'network access is denied' error.
💡 Why You Are Getting This Error
- The primary cause of this issue is related to the way Windows handles file access permissions when using OWA in IE8. When attaching a file from a local shared drive, the application may not properly authenticate the user's credentials or may not account for the specific security settings applied to the mapped drive.
- Another possible reason for this error could be related to the configuration of the Exchange Server or the Windows operating system itself. In some cases, specific services or processes might interfere with file access permissions, leading to the 'network access is denied' message.
🚀 How to Resolve This Issue
Enabling the NTLMv2 protocol and adjusting Windows security settings
- Step 1: Step 1: Open the Control Panel in Windows 7 and navigate to "User Accounts" > "Manage another account". Click on the user account associated with the local shared drive and click on the "Change" button next to "Location". Select the mapped drive letter (e.g., H:) and click "OK".
- Step 2: Step 2: Open the Start menu, type "regedit" in the search bar, and press Enter. Navigate to the following key path: HKEY_LOCAL_MACHINE\System/currentcontrolset\Control oaudits. Create a new DWORD (32-bit) value named "EnableLVM" and set its value to 1. Restart the Windows Explorer service by clicking on the "Stop" button next to it in the Task Manager.
- Step 3: Step 3: Open the Command Prompt as an administrator, type the command `netsh http add urlacl url=h: o iles user=DOMAIN\껜4cEa` (replace DOMAIN and uAeDc4cEa with your actual domain username), and press Enter. This will grant access to the mapped drive for the specified user account.
Configuring Exchange Server settings
- Step 1: Step 1: Open the Exchange Management Console (EMC) on your server, navigate to the "Organizational Settings" > "General" > "Web Client Configuration". Click on the "Advanced" tab and ensure that the "Use NTLMv2 authentication for web client connections" checkbox is enabled.
- Step 2: Step 2: In the same EMC console, go to the "Organization Configuration" > "AD DS Attributes". Ensure that the "Default authentication protocol for web clients" is set to 'NTLMv2'.
✨ Wrapping Up
By following these steps, you should be able to resolve the 'network access is denied' error when attaching files from a local shared drive in OWA on IE8. If you have tried both methods without success, it may be necessary to consult with your Exchange Server administrator or IT support team for further assistance.
