After your mailbox has moved to Office 365 (Exchange Online), you will no longer be able to manage the distribution list from Outlook, as the distribution lists are still on NMBU’s local mail servers. Don’t worry, you’ll still be able to do this, but in a different way.
To get started, you need to have a new shortcut on your desktop of your PC or in HomeOffice.
This shortcut can be copied from “Y:\Temporary\Temporary\Distribusjonslister” to your desktop
Run the shortcut you copied above. Search and find your distribution list. You have to be owner to edit.
