You don't need a tweak the only thing you need is Outlook SP3 install and up to date in your system

NOTE:  Microsoft is diminishing support for Outlook 2010 - consider upgrading to Outlook 2016 to have the latest features.

In order to use Outlook 2010 with Microsoft Office 365, you must be running the most recent version of Outlook 2010.

After the account configures, click Finish.
Start Outlook if you aren't already in it.  Outlook will open, but it may take several minutes as it prepares for the first use.
