An asterisk * in the title indicates the field is mandatory.
If a field has a default value, it is shown in the Description column.
If the field type is an array, the Field Name has a .[n] suffix, where n is the array index placeholder.
Object and array field names are listed to provide context. If a field belongs to an object or an array, the full field name is shown in dot separated notation.

Title		Description	Details
AdminDisplayName		The AdminDisplayName parameter specifies a description for the policy. If the value contains spaces, enclose the value in quotation marks (").	Field Name: AdminDisplayName Type: String MaxLength: 1024
RotateOnDate			Field Name: RotateOnDate Type: String MaxLength: 1024 Format: date-time
DomainName *		The DomainName parameter specifies the domain in your organization that you want to enable DKIM message signing for. By default, DKIM message signing is enabled for the initial .onmicrosoft.com domain in the organization (for example, contoso.onmicrosoft.com).

BodyCanonicalization		The BodyCanonicalization parameter specifies the canonicalization algorithm that's used to create and verify the message body part of the DKIM signature. This value effectively controls the sensitivity of DKIM to changes to the message body in transit. Valid values are: • Changes in empty lines at the end of the message body. Simple Only changes in empty lines at the end of the message body are tolerated.	Field Name: BodyCanonicalization Type: String MaxLength: 1024

Simple No changes to the header fields are tolerated.	Field Name: HeaderCanonicalization Type: String MaxLength: 1024

KeySize		The KeySize parameter specifies the size in bits of the public key that's used in the DKIM signing policy. Valid values are 1024 or 2048. The default value is 1024.	Field Name: KeySize Type: String MaxLength: 1024
NumberOfBytesToSign			Field Name: NumberOfBytesToSign Type: String MaxLength: 1024
Selector2PublicKey			Field Name: Selector2PublicKey Type: String MaxLength: 1024
Identity		The Identity parameter specifies the DKIM signing policy that you want to view. You can use any value that uniquely identifies the policy. For example: Name The domain name (for example, contoso.com). Distinguished name (DN) GUID	Field Name: Identity Type: String MaxLength: 1024
DistinguishedName			Field Name: DistinguishedName Type: String MaxLength: 1024
OriginatingServer			Field Name: OriginatingServer Type: String MaxLength: 1024
Name			Field Name: Name Type: String MaxLength: 1024
Algorithm			Field Name: Algorithm Type: String MaxLength: 1024
