Domain user how to associtae different email address to him/her

Question

Hi

We are using Active Directory with Exchange server 2003 and client PCs are XP SP3.

I have got a user Allen (his position is a manager) currently he is using an object user called NMA with an associated  email address : [email protected] ,,,,(fake address)

Right now he has got 230 555 items in that mailboxes ([email protected]).

He asked me that he wants to use a different email address because his position in a company is a manager and he should not be using the [email protected].,,,instaed he should be using:  [email protected]


When I checked " Active Directory Users and Computers " I have seen an user object  for a manger (created while ago) with an email associated to it as [email protected] (no one is using it) ,,,,,,has few emails 95 in it (95 items)

1- How can I migrate (move) all emails and profiles from previous outlook for [email protected] to [email protected] ????

2- I do not like to disbale [email protected],,,,because it will used by another employee

3- Is there away that we can keep 95 items within [email protected] ?

I found those two when I googled
