If you migrate from an on-premise or local Exchange server (to do only AFTER the migration is complete): 

Step 1: Backing up the IIS configuration

First backing-up the current local IIS configuration is very important. If for some reason you need to undo these actions later on, this backup will allow you to do so easily:

  1. Open an elevated Windows command prompt (i.e. run cmd.exe as an administrator).
  2. Run the following command to back up the IIS configuration:

%windir%\system32\inetsrv\appcmd.exe add backup "Before Removing Autodiscover"

Step 2: Removing the Autodiscover Virtual Directory

  1. Open an elevated Exchange Management Shell (i.e. Run as an administrator).
  2. Retrieve the current autodiscover virtual directory with the following command:

Get-AutodiscoverVirtualDirectory | fl Name, Server, InternalUrl, Identity

  1. Copy the entire Identity value to the clipboard, including any space and (Default Website Site), if present.
  2. Remove the autodiscover virtual directory with the command below. The full identity value should be enclosed in quotation marks:

Remove-AutodiscoverVirtualDirectory -Identity "identity value retrieved above"

  1. Check that the autodiscover virtual directory is gone. This command should now return nothing:

Get-AutodiscoverVirtualDirectory | fl Name, Server, InternalUrl, Identity

Step 3: Removing the AutoDiscover Service Internal URI

  1. Open an elevated Exchange Management Shell (i.e. Run as an administrator).
  2. Retrieve the name of your client access server:

Get-ClientAccessServer | fl Name, AutoDiscoverServiceInternalUri

  1. Remove the current AutoDiscover Service Internal URI with the command below. The name of your client access server should be enclosed in quotation marks:

Set-ClientAccessServer -Identity "NAME" -AutoDiscoverServiceInternalUri $NULL

  1. Check that the AutoDiscover Service Internal URI is gone. This command should now return a blank field for the AutoDiscoverServiceInternalUri:

Get-ClientAccessServer | fl Name, AutoDiscoverServiceInternalUri

It is not a certainty, but users may have to create a new Outlook profile afterwards. However, its settings should not revert to the old service anymore.
