Configuring / Publishing S/MIME X.509 Certificates in M365

Hi,

 

we have the possibility to gather free S/MIME Certificates. Since we are Cloud-Only in a M365 E1-License I wonder, how I could make use of that. Since we don't have a AD/ADDS Server to collect and sync S/MIME Certificates, I wonder how it is possible to publish those within a Cloud-Only Situation.

All Setup-Guidelines from Microsoft refer to a ADDS Server and no reference on what to Do when Cloud-Only.

 

Does anyone here have an idea to follow suite and make those Certs available (especially in OWA)?

    First make a cup of coffee and wait, by the way, check the Microsoft service health page, do not rush when this happens.
