ACL (Access Control List) Encryption on Lotus Notes Database

Summary: NSF to PST file converter software is used by those users who are migrating from IBM Lotus Notes to MS Outlook. Many users have tried the conversion process manually, but they failed to export every Single item of NSF to PST. So the optimum solution for NSF to Outlook conversion is a third party tool because the professional tools give the guarantee of conversion without losing a single data from the file. The easy shortcut for Lotus Notes to Outlook migration is NSF to PST Converter.

Being a data well-wisher I have provided the NSF to PST converter to a needy Manager who was working in a multinational company. His company has decided to switch the email client service from Lotus Notes to Outlook and therefore he bought our software. But while converting NSF file to PST he was facing a Database Cannot be open, it is encrypted error. Let’s see what he has to say to us:-


“Hi Sir, Recently I have purchased NSF to PST converter from your website to convert NSF files to PST. As I am migrating from Lotus Notes to Outlook so it is necessary to convert Lotus Notes NSF files to Outlook PST. But when I was converting NSF files to PST then I faced an error This Database has local access protection and you are not authorized to access it. Well, I am in the worst scenario and I don’t know what todo? Kindly help me out because I want to view my NSF file data in my Outlook account. I don’t want to face Encryption error again and again. If there is any shortcut method to fix this issue then inform me immediately.”

Type of Error - database Cannot be Open, it is Encrypted.

Cause - NSF file is encrypted and therefore it can’t be accessed in Software and MS Outlook.


You can decrypt the NSF files with the help of Lotus notes email account where it had been encrypted. You should access the account of that NSF file and from there you can easily decrypt the data.

  • Go to the File Menu on the Top-Left corner of the page.
  • Point the Cursor on Security and then Click on User Security.
  • Click on Notes Data and then select Databases.
  • Select Do not Locally Encrypt option and Click on OK.
    Do not Locally Encrypt

Now you must resume the conversion process and I suppose now you’ll not face any kind of encryption error. You can easily convert and export NSF files to Outlook and access all of them in the software without any encryption error.
