Your Digital ID name cannot be found by the underlying security system on Microsoft Outlook

You can get rid of the error by trying out different hacks like verifying your certificates, enabling client authentication, tweaking the registry, and more. However, in this article, I will be having a look at the following hacks:

  1. Verify your certificate
  2. Enable the Client Authentication & Secure Email option
  3. Edit Registry
  4. Remove Problematic Senders Certificates

Now let me talk about these fixes individually below:

1] Verify Your Certificate

The first thing you should do is make sure you have a certificate installed. If there is no certificate at all, then it won’t be able to encrypt your email.

To verify this, follow the below steps:

  • Launch Outlook and click on File> Options.
  • Next, click on Trust Center from the sidebar.
  • Then click on Trust Center Settings located under Microsoft Outlook Trust Center.
  • Go to the Email security option, and next to the settings button, look for cert. title.

Now open the certificate title and check whether it is blank or not. Then click on the settings button, and you can select the certificate.

If the certificate is blank, then do install one and then check if you are still getting the same error or not.

2] Enable the Client Authentication & Secure Email option

Many users have confirmed that the issue got fixed after they have enabled client authentication and the secure email option.

So you can do the same by following the below steps:

  • Open Windows Search and type Internet Options
  • Click on Internet Options and go to the Content tab
  • Click on Certificates > Advanced option
  • Now look for the Client Authentication and Secure Email option and place a checkmark next to them.
  • Click on OK to save the changes.

Once done, try to encrypt the email and see if the issue is still appearing or not.

3] Edit Security Settings in Registry

You can also consider editing registry settings. However, editing registry files can put your computer at risk.

So it is recommended that you take a backup of your registry files before editing them. Once you have taken a backup, follow the below steps:

  • Press Windows Key + R to launch the Run box.
  • Type regedit and press shift+ enter to launch Registry Editor.
  • Go to the following path:
  • Now right-click on the blank space on the right-side Window, click on New > DWORD Value and name it as UseAlternateDefaultEncryptionAlg
  • Once created, double-click on it and change the value from 0 to 1
  • Next, follow the same steps to create a value of STRING and name it DefaultEncryptionAlgOID
  • Then double-click on the entry and change the value to 1.2.840.113549.3.7

That’s it. Now go to Outlook and try to encrypt the email and see if it worked.

4] Remove Problematic Senders’ Certificates

There could also be a chance that the error occurs because of a problematic sender certificate. So consider deleting it and see if it works for you.

To delete the sender certificates, follow the below steps:

  • Open Run prompt, type MMC, and press Shift + Enter to launch Microsoft Management Console
  • Next, press CTRL+ M keys to open the Snapin Windows
  • Double-click on Certificates, and select the My User Account option > Finish
  • Go to  Certificates > Current User, then Other People, and then on Certificates.
  • Next, delete the problematic sender certificates
  • Then close and save console settings to Console 1

That’s it. Finally, check if you are still encountering the Your Digital ID name cannot be found by the underlying security system error.
