Sbs 2011 Migration to 365 - Autodiscover change
If you are migrating from exchange on site to exchange 365 you may notice the machines will still look locally for the auto discover reference and not go to your new 365 setup. In Exchange PowerShell on your SBS server run the below command - Set-ClientAccessServer –Identity “your CAS servername” –AutoDiscoverServiceInternalUri $NULL *Putting your server name in the command. After this has been done the machines will no longer look locally for the auto discover record Buy me a beer :)
