Hello My proxy settings for my clients who use SBS 2011 are all of the sudden disappearing. This has been working fine for over a year now. I use one domain as the primary domain which I set the certificate up for. I have a SRV in place for this domain and when I use Microsoft Analyser to test the Autodiscover it passes. I used Shell commands and see the external host matches what is on our certificate. The one odd thing I am seeing is when I run Get-Outlookprovider I do not see a a EXPR Name. Would be great full for any assistance in troubleshooting this. Seems odd everything was working and now its stopped.
