SMTP settings, please help!!!!!!

Hi there,

We are using the AD Manager Plus and Exchange 2010.
My organizations SMTP naming convention is Firstname.Lastname@Domain.com.

Our problem. Currently if the new SMTP address conflicts with the pre-existing SMTP address. A legacy mailbox is created with no associated email address which then affects the creation of the users Lync account.

If a user already has an SMTP address e.g. John.Doe@domain.com and a new user is being created in AD Manager Plus with the same names (John Doe),
when it comes to making the new SMTP address for this user is it possible to automatically make it John.Doe2@domain.com?


Look forward to your reply,

Regards,

Willus
