- The IS&T O365 representative will work with each DLC's Administrative Officer or Program Administrator to determine the cutover date and time when the emails for everyone in the DLC will be completely migrated from the MIT Exchange servers to Office 365 Email and access to MIT Exchange will be cut off and access to Office 365 Email will commence.
- There will be NO notification from IS&T that the migrations are done or that the cutover has happened. The cutover will just happen at the appointed date and time and when it does, some users in some clients like Apple Mail will begin to see errors from their MIT Exchange email client. Users should wait until they start seeing error messages before they do anything.
- When users see error messages at the appointed cutover date and time, it's time for the 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 (except maybe approve the change to the new O365 servers in Windows 10). Apple Mail users will need to remove their old broken Exchange accounts and add a new Exchange email account for O365.
