Turn off Suggest names while completing TO, CC and BCC fields in outlook through Intune

Copper Contributor



I have recently received a request to turn off this particular option from Outlook. As we do not have any on-prem AD, the way to manage all applications is via Intune.


I have researched and found the settings under Configuration profiles-> Settings Catalog

Outlook Options > Preferences > E-mail Options > Advanced E-mail Options


The option works fine when applied and pushed initially, but once the device is rebooted/ outlook is restarted the options revert back to default.


The same case happens when i try to edit the registry manually using powershell.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Preferences - D-Word "ShowAutoSug" = 0


HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\outlook\preferences - D-Word "ShowAutoSug" = 0


Does anyone know the reson behind this?
