I am looking to use the minimal amount of administration to change all of my default e-mail accounts in my domain to a new e-mail address starting October 8th.  I am not sure how to do it with a large number of users outside of going in user by user and changing their account but in 200 users this can be time consuming.  Currently all users have 5 e-mail address.  the would be there default.  I need to make the new default to be be their new default.  I heard there is a way using EMS using a get and a set command which sounds the easiest, but what would the commands be or is there an easier way via the EMC?

I would use the tool ADModify to make these changes.  It's free and will allow you to do all the changes in bulk.

I don't see how that would select a second e-mail address as the new default.  All conditions don't apply so I said all recieptient types on the introduction, on the e-mail address section it looks like I enter my new default e-mail adress, but it dosen't say it will set it as the default.

I reviewed my default policy for some guidence and I can't see where you set the default.  It has one e-mail address selected as the default and is bolded, but I need to set a new bolded (default) account.  What controls that?
