ADManager Plus enables you to define a custom format for different naming attributes in AD. Once you have created a custom naming format, you can apply it to multiple AD users, at once. 

Steps to create a custom naming format using ADManager Plus:

Let's assume that the new logon name of a user whose FirstName is John and LastName is Smith, must be S.John@domainname.com

For this:

1. Login to ADManager Plus and go to the Admin tab. 


2. In the Custom Naming Format section, click on Add New Format.


3. Enter a suitable Format Name.


4. Expand the drop-down situated beside Select Data, and select LastName. In the drop-down field beside with, select the First option, and enter 1 in the adjacent field. In the field next to Characters, select the Given Case option, and click Add. 


5. Similarly, expand the drop-down situated beside Select Data again, select Dot and click Add.


6. Expand the drop-down located beside Select Data once again, and select FirstName. In the drop-down field beside with, select All. In the field next to Characters, select the Given Case option, and click Add. 


7. Click Save. 

Steps to apply a custom naming format for logon names of all AD users:

1. Click the Management tab.
