The IS&T O365 representative will work with each DLC's Administrative Officer or Program Administrator to determined the date and time when the emails for everyone in the DLC will be migrated from the MIT Exchange servers. When the cut over from MIT Exchange to O365 Email happens it will happen it is be up to each user (with any available local IT help) to delete their old email settings and add an Exchange Email account back into the client program, if needed. Most MS Outlook client users won't need to do anything. Apple Mail users will need to remove their old broken Exchange accounts and add a new Exchange email account for O365. There will be NO notification from IS&T that the migrations are done or that the cutover has happened. It will just happen at the appointed date and time and when it does, you will begin to see errors from your email client.
At the cutover date and time the migration will have completed and access to the old MIT Exchange Email will be cut off and access to your emails on O365 is online and active.
