S/MIME functionality available in Outlook for iOS TestFlight

Ross Smith IV 

I'm eagerly awaiting the S/MIME functionality in iOS, thanks for your very informative post.

Three questions I really hope you can answer:

1) Will Outlook for iOS support fetching public S/MIME details from AD/AAD from the UserCertificate and/or UserSmimeCertificate attribute?

2) Will Outlook for iOS support  fetching public S/MIME details from a connected LDAP Address book, just like Outlook for Windows?

3) Will Outlook for iOS support a way for third party solutions such as MDM or other Certificate Life Cycle Management solutions , to configure a present Outlook for iOS with relevant S/MIME and address book settings?

Reason why I'm asking are all related to end-user experience.

A techie person will understand how to manually configure an S/MIME and manually configure an addressbook, and will likely be annoyed but understand why a recipients certificate will first need to be save and installed onto iOS before being able to send a message.

But most users have no clue and need to be able to simply use the Outlook for iOS app with S/MIME support for encryption and/or signing.

Also you state that not everybody needs S/MIME and likely will have sufficient use with Microsoft's proprietary encryption solution. However many countries are adopting a requirement for example for S/MIME based email signing when privacy sensitive information is shared such as medical data. So expect hundreds of thousands if not millions worldwide of non-techie people who professionally are being forced into  S/MIME simply due to (GDPR) regulations
