When testing the Outlook Anyhwere configuration using the Exchange Remote Connectivity Analyzers (ExRCA) you might encounter the following error message:

Autodiscover settings for Outlook Anywhere are being validated.
ExRCA wasn't able to validate Outlook Anywhere Autodiscover settings.
The AuthPackage wasn't specified in the EXPR section of the Autodiscover response.

ExRCA OutlookAnywhere error

If you encounter this error, you need to verify the following two attriobutes of the Outlook Provider configuration:

  • Server attribute
  • CertPrincipalName attribute

Server Attribute

Remove any dedicated server configuration.

Get-OutlookProvider EXPR | Set-OutlookProvider -Server $null

Now the appropriate CAS FQDN will be used.

CertPrincipalName Attribute

The CertPrincipalName attribute must match the common name (CN) of the SSL certificate. If a wildcard certificate is being used, it is required to configure the CertPrincipalName for the certificate

Set-OutlookProvider EXPR | Set-OutlookProvider -CertPrincipalName msstd:*.mcsmemail.de
