[Windows Central Question]

I have all contacts mixed up so want to upload a new contact list. I have deleted all contacts from my primary hotmal account however in phone book all contacts are still showing

[RumoredNow]

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.
