PRE-TRANSITION

What needs to be done pre-transition

  1. Read/skim the IS&T O365 Pre-transition information: https://kb-mit-edu.ezproxyberklee.flo.org/confluence/display/istcontrib/Office+365+Pre-Migration+Information
    1. Make a note if any of the listed conditions apply to you.
    2. Plan contingencies if a condition applies to you.
  2. Clean up your emails including purging deleted emails and junk emails .
  3. Notify IS&T of ANY AND ALL shared MIT Exchange calendar resources as they will need to be migrated as well.
  4.  

The TRANSITION

On Monday September 19th 2022, Albert and Dan were migrated from MIT Exchange to MIT Outlook 365O365 Email. As Apple Mail and iCal users these are the notes of what we saw.

When the cut over from MIT Exchange to MIT Outlook 365 O365 occurs you may see errors. As Apple Mail users this is what we saw. This means that your email has been transitioned to Outlook 365 O365 and you should stop using MIT Exchange.

 

What To Do

You will need to delete your old MIT Exchange from Apple Mail and add the new MIT Outlook 365 O365 Mail account.

For me with about 42k email messages the download took 5 hours on campus over an Ethernet connection. At home I left my machine on and running overnight. Home internet speeds will vary depending on your plan. Since the end of Net Neutrality, cheaper plans usually mean slower speeds.

During the Download

Apple Mail was NOT really usable on the Mac at all during the download as it was hung most of the time. We recommend users leave Apple Mail running to download the emails but do NOT use it to check your email while it is busy downloading your emails from the Outlook365 cloud from Microsoft. Instead, use the NEW O365 OWA webmail on your preferred browser which can be found at outlook.office.com . Users who have been migrated to Outlook 365 O365 should stop using the old Exchange OWA (owa.mit.edu). It will no longer work for you.

Instructions on how to access the new O365 OWA Webmail at outlook.office.com can be found here:

Mobile Devices

All iOS and Android devices will need to have the email accounts deleted off the devices and added again as the old Exchange accounts are now on Outlook Office 365.
