The TRANSITION

On Monday September 19th 2022, Albert and Dan were migrated from MIT Exchange to MIT O365 Email. As Apple Mail and iCal users these are the notes of what we saw.

When the cut over from MIT Exchange to MIT O365 occurs you may see errors. As Apple Mail users this is what we saw. This means that your email has been transitioned to O365 and you should stop using MIT Exchange.

What To Do

The IS&T O365 representative will notify you at the pre-determined date and time when your Emails have been cut over. This means the email migration has completed and access to the old MIT Exchange Email has been cut off.

You will need to delete your old MIT Exchange from Apple Mail and add the new MIT O365 Mail account.
