Related to the outlook add-in for Acumatica... When our users try to authenticate with their azure login, we see the following error.

NOTE:
we have 2 factor authentication on for our users through office 365, but i don't think that is the issue as i disabled and also tried using a app password which would bypass the 2 factor
we have customized the outlook plugin and it works just fine when use a regular login (direct username and pwd into acumatica as opposed to using single sign on)

We are running Acumatica 2020 R1, and have this working. I am not sure if it will work in 2019R1, but you can give it a try.
Our environment is synced with Local AD through Azure AD Connect. We have seamless SSO enabled with Passthrough Authentication, and the group policy trust enabled for the workstations. This allows the users to sign into office 365 from their domain controlled computers.

When we enable automatic signon through AzureAD in the web.config, it works like a charm. We had issues in previous versions of Acumatica with our ADFS deployment. To enable automatic SSO in Acumatica you can modify your web.config:
<externalAuth authUrl="Frames/AuthDock.ashx" silentLogin="Federation" externalLogout="True" selfAssociate="True" instanceKey="" claimsAuth="False">
I would give this a try on off hours to see if it works with Outlook, and maybe change your production instance to sign in this way. You can always get to the login page by visiting https://acumaticainstance/Frames/Login.aspx?SilentLogin=None
Maybe setting auto signin will fix outlook and be easier for those users, and be more beneficial than the non-azure users?
