Office 365 Domain Disable AutoComplete Option

[RanchoJack]

I have a client that would like to disable Outlook's Auto-Complete for the whole domain. 

Running Office 365 ProPlus Version 2002 (Build 12527.21104) 

Is there a way either by scripting or registry edit to disable the "Use Auto-Complete" option?  I've already looked in the registry.  We can instruct the users to disable the option but would like to set a policy to enforce the setting.

Just use the reg key:

REG ADD "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Preferences" /t REG_DWORD /v ShowAutoSug /d 0 /f
