- There will be NO notification from IS&T that the migrations are done or that the cutover has happened. It The cutover will just happen at the appointed date and time and when it does, you some users in some clients like Apple Mail will begin to see errors from your their MIT Exchange email client. Users should wait until they start seeing error messages before they do anything.
- When you users see error messages at the appointed cutover date and time, it's time for you the user(with any available local IT help) to delete your 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.

- Internet Update Lag
Because the O365 email servers are no longer on campus, users should be aware of potential internet lag when composing emails via a client program (like Outlook or Apple Mail) to the O365 server at Microsoft. This lag may increase during busier times of the day like noon and 4pm. It is therefore recommended all users wait 3-5 seconds before hitting send(depending on the time of day) after the text of a particularly important email is completed to make sure the last edits made to your important email gets saved to the Microsoft's O365 server before sending. - Windows 10 users
Due to increased data security in Windows 10, MS Outlook may ask you to approve the change to the new O365 Servers. Users should approve the change.
