Hi,

One of our customers is evaluating to change to Zoho Business. He want to preserve the organization usernames, but searching we found that some of their usernames are already taken.

I mean, a user logs in the existing mail server as name.lastname/password but in Zoho Services name.lastname is already taken.

Does exist some way to got same username for several organizations without LDAP authentication?, something like this:

      Organization1
            username1
            username2
            username3
      Organization2
            username1
            username2
            username3
