Quite possibly if you have more than one account, all those contacts got synced to another account as well. Perhaps they are now also in your Outlook?

To delete all contacts... Delete all the secondary accounts and leave only your Microsoft account. Delete the remaining contacts. Sync the account from the phone.

On your PC Browser, go to each account you will add back to the phone and double check the contacts there before linking it to the phone.
