Configuration with Modern authentication (DE)

This is our recommended configuration. We can use this if you don't need to back up special mailboxes or dynamic distribution groups.

Details we need: 

  • M365 Global admin username
  • Admin password

Check out this article to create a Global admin in M365.

During the configuration process, we'll:

  • create a self-signed certificate that Veeam can use for authentication 
  • log in to O365 through device log on
  • a new application will be registered named "VeeamM365" on your Azure AD
  • the required permissions will be assigned for the application
  • Optional: log in to Teams in order to start the free Teams Exploratory license (you'll receive an email about it)
  • create the jobs to back up your M365 data

Create connection to the M365 organization

Log in to the SP console and click on Configuration in the top right hand corner.
