OIM 11g R2 - How to allow OIM with duplicate email address.

By default OIM does not allow duplicate email address for users but some time due to business requirement we have to allow.

Click on create as highlighted below.

Add the below Property and click on "Perform".

Property Name = Email Uniqueness
