Hello!

Thanks for getting back to me. 

Just to be sure, like I had mentioned in my original post, I had 3 certificates that were expired which I simply pressed renew and it renewed them. 

Is it possible that the renew didn't complete correctly?

Here is what my OAUTH looks like now

 

One think I did notice was on a working server vs this non working server the certificate called 

WMSVC-SHA2 is different. 
The working server has SMTP checked off as a service and the non working server has SMTP not checked off.
 
Would that be a possible cause also?
 
Thank you!

    Hello everyone,
    It's been a long time since I've posted regarding this issue but I must admit I am at wits end. I do not know what the issue is. I recreated the Microsoft Exchange Server Auth Certificate, it expired on 4/17/2028 but I still cannot log on to OWA (or connect any new user email to any mobile device)
    I really have no idea what the issue is.

    The original poste said it was Exchange 2019 but it's actually 2016. I don't think that makes a difference but I really need some help I don't understand what the issue is.

    Thanks
