OoO not working because AutoDiscover does not work
1 First: Always check Certificates and DNS 1.1 Check if your certificates are configured correctly and if they have expired. Open the Exchange Management Console and run: Get-ExchangeCertificate | fl Review your certificates and ensure that they have not expired 1.2 Check DNS A good way to test DNS is using NSLOOKUP.
