If I want to use oAuth, with or without HMA, will I still be able to certificate-based auth besides for Exch 2016/19?

May I know if it is possible to only enable HMA of part of the user in my organisation?

Would like to implement it by phases.

Thank you

Carlos

Hi Bala,
you can check your VDirs by the steps outlined here:
https://docs.microsoft.com/office365/enterprise/configure-exchange-server-for-hybrid-modern-authentication#verify-virtual-directories-are-properly-configured
OAuth should be listed.
Ciao,
Ingo

Thanks for the blog, if i am having Exchange 2013 (CU19) how can i enable OAUTH for my clients. Is the HMA feature in Exchange 2013 (CU19) automatically accepts OAUTH tokens? or i need to run any scripts?

Hi Carol,
I think it’s going to be hard to remove the Hybrid config. But what you can do is removing the on-premises namespaces from the config.

Any instructions or should I just work backwards?

Hi Kiran,
these clients doesn’t understand that the server is offering Modern Auth and will ignore it as they don’t understand. That’s why you need to enable MA on 2013 clients.
Short answer:
Nothing for these clients.
Ciao,
Ingo

Whats is the end user impact if we enable HMA. IF organisations have legacy mail clients like outlook 2010,2007 and legacy protocols imap and pop3 configurations?
