Hi,
I have migrated a customer of mine off exchange 2010 on premise to office 365 and I have amended the registry on the local clients so that they connect directly to office 365 and ignore the local autodiscover for old local exchange server.
I now want to remove the exchange 2010 from the domain, is there a migration guide for the safe removal of the exchange server?.
Also prior to removal of the exchange server is there a command that can be run to remove the local autodiscover records from AD so that the clients auto matically look to the office 365 servers?.
Here is the guide you need Uninstall Exchange Server 2010 from SBS 2011. If you have completed this the AD no longer has information about autodiscover on the SBS and the clients should be fine.
