Identity	Key	String	The Identity parameter specifies the DKIM signing policy that you want to modify. This should be the FQDN.
AdminDisplayName	Write	String	The AdminDisplayName parameter specifies a description for the policy.
BodyCanonicalization	Write	String	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 'Simple' or 'Relaxed'. 'Relaxed' is the default.	Simple, Relaxed
HeaderCanonicalization	Write	String	The HeaderCanonicalization parameter specifies the canonicalization algorithm that's used to create and verify the message header part of the DKIM signature. This value effectively controls the sensitivity of DKIM to changes to the message headers in transit. Valid values are 'Simple' or 'Relaxed'. 'Relaxed' is the default.	Simple, Relaxed
KeySize	Write	UInt16	The KeySize parameter specifies the size in bits of the public key that's used in the DKIM signing policy. Valid values are 1024 and 2048	1024, 2048
Enabled	Write	Boolean	The Enabled parameter specifies whether the DKIM Signing Configuration is enabled or disabled. Default is $true.

Credential	Write	PSCredential	Credentials of the Exchange Global Admin
ApplicationId	Write	String	Id of the Azure Active Directory application to authenticate with.
TenantId	Write	String	Id of the Azure Active Directory tenant used for authentication.
CertificateThumbprint	Write	String	Thumbprint of the Azure Active Directory application's authentication certificate to use for authentication.
CertificatePassword	Write	PSCredential	Username can be made up to anything but password will be used for CertificatePassword
CertificatePath	Write	String	Path to certificate used in service principal usually a PFX file.
ManagedIdentity	Write	Boolean	Managed ID being used for authentication.
