By token do you mean SAML token or Microsoft token signing? Under ADFS, in the section that shows token signing certificate I see some other certificate than one in IdP but when I try to update it I see a warning message that basically says automatic rollover of certificate feature would no longer work if I choose to put my own certificate. However, I have updated IdP certificate in ADFS using Set-MsolDomainAuthentication and when I retrieve this certificate using Get-MsolDomainFederationSettings -DomainName domain.com I see SigningCertificate identical to signing certificate in IdP.
