Exchange Migration to O365 – Known Issues

1. Outlook profiles cannot be created with migrated mailboxes that are not already Kerberized (does not use Kerberos authentication or have a Kerberos password). These mailboxes also cannot be added to another user’s Outlook profile. They are, however, accessible via a web browser using Office 365 (O365).
2. In some cases mailboxes with shared permissions that have granted access to other users (e.g. Inbox or calendar) in order to edit/view content do not migrate successfully. Permissions have to be reapplied.
3. Distribution lists will need to be managed by IS&T at this time in order to add or remove members.
4. A few people have noted that old calendar invitations get re-sent a year or more after the original invite, in particular with those who have invitees outside of BU. One theory may be that some messages were “stuck” in their Outbox. IS&T is investigating this as well.
5. Some credential pop-up problems for Outlook (as well as Skype for Business) after migrating to O365. These have been very few so far, most of these issues have been in the on-premises environment. IS&T is investigating this. They do not know if the Skype fix will also cure the Outlook issue, since they don’t have details from Microsoft on the solution yet.
6. Viewing Shared Calendars across premises
   1. Once your mailbox has been migrated, shared calendars still on-premises may only show free/busy blocks, rather than meeting details.
   2. You cannot set permissions to view a calendar cross-premise. As departments and schools are migrated, this will change.
   3. Those with whom you share calendars who remain on-premises may see a pop-up after your mailbox is migrated, asking them to “quit and restart Outlook”. That allows the calendars to sync cross-prem. Similarly, you may see/have seen this pop-up, as those with whom you share calendars are migrated to O365.
   4. A client may need to re-share their calendar, and it is best done via OWA (Outlook Web App), not the Outlook desktop client.
7. iOS version must v8.3 or greater.
8. Microsoft has introduced something called “Calendar Repair Assistant” that behind the scenes goes and fixes missing calendar items, items that are out of date and had been changed since, etc. It apparently works pretty well, but one thing it does is if there are any notes in the original calendar item, or if there were attachments to the calendar item, they are deleted by the Calendar Repair Assistant. IS&T is looking into this now, as it was just reported very recently by a couple people.
9. Majordomo mailing lists- don’t work if you try to access them via O365. IS&T believe they have a fix for this and it should be resolved fairly soon.
