Export Personal Information Exchange – PKCS #12 (.PFX) Option Greyed Out

Before configure Out of Band (OOB) Management role on the SCCM server, you'll need to export the .PFX file from the AMT Provisioning Certificate. But for my case, the option to export the .PFX file is greyed out, and hence restrict me to proceed to the OOB configuration step.

Solution:

1. In the Certificates snap-in, double-click the imported/installed certificate.

2. In the Certificate dialog box, click the Details tab. 

3. Click Serial Number in the Field column of the Details tab, and copy down the serial number. 

4. Open Command Prompt, and type the following:

    certutil -repairstore my "SerialNumber"

    the SerialNumber is the serial number you copied on step 3.

5. In the Certificates snap-in, click Refresh.

6. The certificate should has an associated private key now (notice that the certificate icon is now with a key on it).

After going thru this solution, you should be able to export the .PFX file and proceed to the OOB configuration step.
