Bulk addition of new SMTP addresses
Posted on 2004-11-10
We have a large number of distributed sites running various flavours of Exchange from V5.0 up to Exchange 2003. Each of these Exchange boxes hosts a number of mailboxes. We have a requirement to add a new Internet mail address to every mailbox and to make this new address the primary SMTP address. Any ideas on the best way to do this considering the different Exchange platforms? In total there are over 25,000 mailboxes spread over 34 boxes so manual updates is just not feasible.
We will be totally upgrading our setup soon but we need to implement this for business reasons now
I know that we can do a directory export to a csv file, modify and then re-import on the 5.0 and 5.5 boxes. Can this be done on the Exchange 2000 and 2003 boxes as well?
Are there any limits to the number of records that can be imported in this fashion?
This is an urgent requirement
