When we add or include some contact in our Yahoo Mail account; we usually don’t get much time to review the contact list and find the duplicate entry. This happens to users who are always running out of time.
Sometimes users accidentally added some contacts multiple times. This creates a problem when you try to get the contact information from your Yahoo Mail account and confuse with multiple entries. You need to review each contact carefully. Sometimes users find themselves in a situation of using the incorrect contact.
