Hello - I'm an Exchnage newbie and have the following issue - we have an Exchange 2010 server accepting mail for multiple domains and want to migrate one of them to O365. I found that if you:
Set-ClientAccessServer –Identity “CASxx” –AutoDiscoverServiceInternalUri
$NULL
you're essentially removing the on-premises information with regard to Autodiscover; thus eliminating the conflict that your end users are experiencing between the O365 autodiscover and the on-premises one.
Does this ps command disable AutoDiscover for ALL the domains?
How would you remove AutoDiscover for just 1 of them?
I do have a CNAME record pointing to autodiscover.outlook.com in DNS for this domain.
