Hi,
I am facing the same issue and have not been able to configure it. I actually even paid for the license and contact the support and ran a dead end there.
I’ve been browsing here and looking on various sites and trying to work with our security/system’s team at work to help configure but not able to get around.
I receive the error “The server was found, but authentication failed. Check the email address and password”.
I have tried the registry edit from a knowledge article and various other steps that support suggested but stalled with support when I received a certificate installation pop up from the emclient, in which I was referred to systems team to install it.
It’s installed, but I am still not able to authenticate through MFA to get the account setup in emclient.
I hope this gets resolved. I tried mailbird and a few other clients and preferred emclient, but it does not function right now and I could not recommend it based on this.
