Autodiscover pointing internally but needs to point to 365

Hi,

I have moved my MX and autodiscover records to office 365 but when I go to add an exchange account in Outlook it is still pointing to our old internal exchange server. Is there a specific dns record I need to add in order for the autodiscover to work for 365?

Depending on your version of Exchange and in general, the domain configuration, domain-joined machines might indeed end up talking to the on-prem server instead of O365. The easiest way to work around this is to instruct Outlook to bypass the local autodiscover query, by populating the reg keys mentioned in this article: http://support.microsoft.com/kb/2212902

All you need for Office 365 is the Autodiscover CNAME dns record, which corresponds to the HTTP redirect method. You can block all other methods and the issue will be solved.

In general, you can also consider other options, such as stopping the relevant services, disabling the virtual dirs, disabling SCP, changing local DNS records, converting mailboxes to MEUs, deleting on-prem mailboxes, decommissioning the local server, etc. All of these are way more disruptive than just using the reg keys, so I'd stick to the simple solution.

Hi,

If you are having Exchange 2007 or above then execute below command to set Autodiscover to null.

Get-ClientAccessServer -Identity "ServerNameHere" -AutoDiscoverServiceInternalUri $null

On your exchange server nslookup:
autodiscover.outlook.com

and create DNS zone "autodiscover.domain.com" in internal DNS then
create blank A records and point then IP Address you received from autodiscover.outlook.com

After above changes restart DNS Service on Server and execute ipconfig /flushdns & ipconfig/registerdns on client machines.

Then try to configure outlook profile.

@Shreedhar  the management shell did not recognize  -AutoDiscoverServiceInternalUri  as a command.

Disregard..the command has to begin with "Set" instead of "Get"
