​Hi,

Our mail system is MS Office 365.  We assign incoming students an email address in the form

   [log in to unmask]

The students may customize that address to something like

  [log in to unmask]

(actually, they seem to test different versions of the address).

All of this is fine.  But.  The Registrar's Office provides the original ID assigned (in an Exchange environment, both addresses are proxies for a real address; the students actually only "SendAs" whatever the customized address is -- in Exchange terms, the "PrimarySMTPAddress".  If no customization, the originally assigned one is used), and faculty can typically use a machine-readable version of the class roll to add subscribers to their class discussion lists. 

I change the addresses as the students customize their addresses, but the Registrar's Office will continue to use the original ID.  I have a powershell script to collect the Primary SMTP addresses for all list subscribers (collected one list at a time from the list report on the web).  From that, I can build a file with all the "quiet change listname old-address new-address" in it.  Our listsever is on a Linux box and I can paste the entire "change" file into pine and update all the addresses via CJLI.  Using the web, I can see how to issue a single change at a time (List Management -> Command", but no way to process an entire file of these.  Or have I missed something (very, very possible).

Yes, this is really clunky, for now it is what we have ...
