Email

The mailbox associated with the Kerberos account is moved as part of the migration process, in turn it's important to know the following:

  • Software clients that handle incoming email for the account being migrated will be interrupted.
  • Forwarding, split or otherwise, may break immediately after migration.
  • Categorization of emails within Outlook clients may break with custom categories.
  • Mail rules will remain untouched.

In addition to this list, IS&T is maintaining a page of Known Issues here.

Calendaring

As the mailbox associated with Kerberos accounts interacts with and determines where some calendars live, here's what to expect will happen to calendars attached to an account being migrated:

  • Permissions for shared calendars with other individuals on Exchange 13 are lost, this includes Resource Calendars. Access beyond viewing Free/Busy times on the calendar is restricted until the calendar is also migrated. The account and the resource mailbox need to be on the same server (whether Exchange or O365); otherwise they cannot edit the calendar.
  • If a non-resource calendar is owned by the individual getting migrated, the calendar gets migrated to O365 alongside the mailbox.
  • If the individual getting migrated to O365 is a delegate on mailboxes or resources that remain on Exchange, this delegation will break as part of the migration.

Shared Calendars / Delegate Access

If you share delegate access to your local Exchange account with others or vice versa, the shared calendar or mailbox may disappear from view and you'll need to supply/be given that access a second time. If you share calendars with others, they will appear as disconnected and may give you errors until those accounts are migrated to O365. Right-click on a calendar and remove it from your view, then re-add it once it has been migrated.

A common example calendar that will need to be reconfigured is "KI: HQ Staff Calendar" or "ki-hq-staff-calendar-res@mit.edu". For instructions on how to do reconnect this calendar as well as others in Outlook, please see below:

Third-Party App Integration

Apps that were connected to the local Exchange mailbox may break their connection, as it has been moved to O365. This includes:

  • No labels
