Office 365 Post-Migration - Outlook for Windows 10

Reconnecting Your Mailbox

Once your account has been migrated, we recommend performing the steps in the following procedure to reconnect to your mailbox in Outlook for Windows.

  1. Upon launching Outlook for Windows, you will receive the following error. In order to resolve it, enter your MIT email address and password, check the box for "Remember my credentials" and press OK.
    • If your computer is tied to a domain, you may need to enter "exchange\" before your email address. For example: exchange\

  2. Once you enter this information, you will receive the below prompt. Press "OK" and restart Outlook.

  3. As your mailbox begins to retrieve your emails once more, you may see the notifications below.

Resource Calendars

If you make changes to resource calendars still present in your Outlook client that were not migrated alongside your mailbox, you will receive the following notification.

In order to remediate this issue, we recommend you:

  1. Remove the calendar from your Outlook client
  2. Restart Outlook
  3. Navigate to your Calendar window > Right-click "My Calendars" > Select "Add Calendar from address book"
  4. Set the search to "More columns" and the "Address Book" field to Global Address List (GAL)
  5. Search for the resource's name and press "Go"
  6. Select the calendar and press "OK"
Note that your account and the resource both need to be on the same server (whether Exchange 13 or O365); otherwise you will not be able to manage permissions or modify, edit, and delete entries on the resource. You will however, be able to see the times the resource is free and busy.
