Hello,
I have to clear AutoComplete before and after migration to Exchange Online.
I would prefer to create a GPO in order to enable/ disable it.
I need a powershell too (working with Exchange 2013).
Thanks in advance for your help.

    Hello @Diego-6531 ,
    There is no effective GPO to clear autocomplete cache in all outlook profile. Instead, you try using an X500 address.
    Please refer the below link
