Detailed requirement: I have Account lookup field(Field Name is "Existing_Account__c") on Lead object. In lead conversion page salesforce by default displays "--None--" option for Account Name. But my business requirement is that- Instead of --None-- option I have to pre-populate account present in custom field Existing_Account__c. So that whenever users click on Convert button Account Name should have valid account instead of --None-- option. enter image description here

You have to specify AccountId 3 times.
