4. To add a new CAA record you need to use an UNKNOWN record type. This is because Microsoft Windows does not provide a specific field to add this particular record.

Note: For more information about the introduction of the UNKNOWN record type to support RFC 3597 from Microsoft Windows 2016 Server, go here:
https://docs.microsoft.com/en-us/windows-server/networking/dns/what-s-new-in-dns-server

To add this, please follow the instruction for PowerShell, using the command below:

Add-DnsServerResourceRecord -name your_own_name -RecordData 1800056973737565656E74727573742E6E6574 -Type 257 -ZoneName your_zone_name
 
-nameYour own designated record name. Example: entrustcertlab.com
-RecordData1800056973737565656E74727573742E6E6574
 
NOTE: This is the Entrust designated hexadecimal code. Make sure you don’t mistype or left out any character or number.
-Type257
-ZoneNameYour DNS zone name.
Example: entrustcertlab.com
Note: Entrust Legacy Zone File (RFC 3597 syntax)
example.com.    IN    TYPE257    \# 18 00056973737565656E74727573742E6E6574

5. At this point the CAA Record has been added.

You can run a command to review your zone records by typing the same command from step 3. You will see that the UNKNOWN record is now showing along with other previously existing records:
 
Get-DnsServerResourceRecord -zonename your_zone_name
