In a few weeks I need to replace the SigningCertificate in Office 365
and I tried to replace the Office 365 SigningCertificate, in the same
way as it is described to set up a new domain in the documentation.

Set-MsolDomainAuthentication -FederationBrandName $dom -Authentication Federated -PassiveLogOnUri $url -SigningCertificate $certData -IssuerUri $uri -ActiveLogOnUri $ecpUrl -LogOffUri $logouturl -MetadataExchangeUri $mex

But it doesn't seems to change the SigningCertificate after the command
has been issued.

Has anyone of you managed to do this in this way?

Best Regards Magnus
