How to Fix "Access to Data Denied" Error 4005 in IBM Notes?

Getting the “Access to Data Denied” or Error 4005 message in IBM Notes is another headache users often face. This typically happens when your user account doesn’t have proper access rights, or the NSF file itself is damaged. Start by checking the ACL for the affected database and verifying that your role has the required permissions. If everything looks good but you still can't access your data, it might be a sign of corruption in the NSF file.
You can try running the ncompact.exe utility to clean up and optimize the file. But if you’re still locked out, don’t worry—eSoftTools NSF to PST Converter can rescue your data. It bypasses access issues and retrieves all mailbox content, including emails, calendars, tasks, and contacts. Once recovered, you can save the data in Outlook PST format while keeping the folder structure and metadata intact.
