Modern Authentication with Veeam, In this article I will explain how to configure the modern authentication with Veeam Backup for Office 365.
What is Modern Authentication visit Microsoft
Veeam Office 365 Modern Authentication
The release of version 4 of Veeam Backup for Office 365, now we are able to use the so-called modern authentication. This means using service accounts enabled for MFA (multi-factor authentication).
We need an Azure Active Directory custom application and a service account that has MFA (Multi-Facture Authentication) enabled. The custom application (App application) registered in Azure Active Directory will allow Veeam Backup for Office 365 to access the Microsoft Graph API. With this access, we can pick up the data from the “Microsoft Office 365 organization tenant”.
In this strategy, the service account will be used to connect to the EWS and PowerShell services.

Assign roles to the service account
The user needs the correct permissions and roles to backup Exchange Online and SharePoint Online. We have the choice to do this via the Exchange Admin Center.
For Exchange Online (Global Administrator or Exchange Administrator) role. Additionally, you need the ApplicationImpersonation role.
For SharePoint Online (Global Administrator or SharePoint Administrator) role.
I have this as testing purposes and for this blog post. I would not recommend assigning the Global Administrator in a production environment. Either uses the Exchange Administrator and the SharePoint Administrator role.
1- Select user account (veeam_vbo).
2- Click on Assigned roles under manage and then click on + Add assignments.
3- Select the role in the Directory role wizard on the left hand side and then click add.
4- Successfully assigned the roles.
SharePoint Admin Center
1- Login with SharePoint Admin Center, select access control, and then Apps that don’t use modern authentication.
2- Verify allow access is selected.
How to grant a service account required roles and permissions
1- Add ApplicationImpersonation role via the Exchange Admin Center. Select the permission tab on the left-hand side. Under admin, roles click the + button to add a new role.
2- Type a role group name and description. Select the Write Scope to default and then click the + button.
3- Under Roles to add the ApplicationImpersonation, Mail Recipient, Mail Search, View only configuration, View only recipient role from the list, and then click ok.
5- Add a member, it means our service account for this new role group. For that click on the + button under Members.
6- Select your newly created service user, click on add button and then click OK.
7- Click on save button.
8- The user has been granted the ApplicationImpersonation role.
To get an app password for an MFA-enabled service account
1- The last thing we need to do before adding our tenant to Veeam Backup for Microsoft Office 365 is to collect your app password. Login with new user account & go through the additional security verification methods for this new account.
2- Now we need to select if we would like to receive text messages or if Microsoft calls you within the configuration of the phone verification. I am going to select an Authentication phone option (country code phone number) and select send me a code by text message and then click Next.
3- Type the verification code and then click on verify button.
4- This app password is wanted within the Tenant configuration in Veeam Backup for Office 365. Copy it in notepad or save it for our later use. Click on the done button.
5- After login to user office 365 account, click on my account icon and then click my account
6- You will be redirected to https://portal.office.com/account. Under my account select the Security & Privacy tab to create and manage your passwords. Click on create and manage passwords.
7- Additional security verification (app passwords) click on create button.
8- Enter a name and then click next.
9- Copy your password and save it in notepad and then click close.
10- You will need to sign in with this user if you have an existing service account. In the right-hand upper corner, select the settings and then your app settings (Office 365).
I have created a new user, so I don’t want to do that here.
