In the meantime if the contacts were just added there's a good chance that they just aren't turned on or visible in the contacts app. It will depend on which app is being used but;
In Google Contacts>press the 3 lines, in the upper left next to search>Settings>Accounts. See and make sure the Outlook account is listed there. If not use the (+) to add the account.
In Samsung Contacts>press the 3 lines, in the upper left under profile pic>Manage contacts>Sync contacts. See if the Outlook contacts are listed here and the slider is active. If not use the Add account to add the account.
Contacts on Android are some times buggy. On older versions of Android it would some times take up to 24 hours for contacts to be restored. I'm not saying that is what is happening here but you might give it a few hours or so to see if they appear. I'm not sure if this is due to when something syncs or refreshes but I've seen a lot of panic over not having all contacts immediately and then have them all be there the next day.
