Recently we've been undertaking a task to move from IBM Domino to Office 365 with particular emphasis on the mail system. One of the first big tasks is to move all of our corporate contacts from the Domino NAB over to the Contacts area of office 365. Corporate Contacts Corporate contacts, in this sense are contacts which are shared by the entire organisation. I'm not talking about actual users who will have an Office 365 licence with your company or about personal contacts, who would normally reside in the personal address book. In our case, we had about 6500 corporate contacts who needed to be migrated. There's a contacts screen in Office 365 which is accessible from the Admin portal. It's under users, then contacts. Exporting from Domino In IBM Notes, open your company's address book and press Ctrl+A on people. If you have your staff and non-staff in the same address book, you'll probably want to sort by company and deselect all the staff. Ne
