Hi, I am having an issue with Autodiscover not passing EXPR attributes which is causing Outlook client connection issues. My auto discover repsonse looks like this:
Autodiscover Account Settings
Autodiscover Account Settings

Basically the response isn't passing EXPR settings at all. I have tried running Remove-OutlookProvider EXPR and then New-OutlookProvider EXPR, Set-OutlookProvider EXPR -CertPrincipalName msstd:mail.domain.com
When I run Get-OutlookProvider everything looks normal with the EXPR settings but they are still not being passed via auto discover. Any ideas on how to resolve this?
