This section covers the following topics:

Scanning a OneDrive Business Target

To scan OneDrive Business, you must add your Microsoft 365 organization as a Target. Each user's OneDrive Business account is represented internally by Microsoft as a "My Site" Site Collection. For ER2 to scan the OneDrive Business user account, we have to be granted permissions to scan these Site Collections.

On the Web Console, browsing an added OneDrive Business Target lists all Office 365 user accounts within the domain. Select only user accounts that have OneDrive Business enabled to add them as scan locations. Scanning a user account that does not have OneDrive Business enabled will result in ER2 reporting it as an inaccessible location.

Licensing

For Sitewide Licenses, all scanned OneDrive Business Targets consume data from the Sitewide License data allowance limit.

For Non-Sitewide Licenses, OneDrive Business Targets require Client Licenses, and consume data from the Client License data allowance limit.

See Target Licenses for more information.

Preparing to Add Target Location

Before adding OneDrive Business as a Target, you have to perform the following on your Microsoft 365 organization:

  1. Add OneDrive Business User Accounts to a Group
  2. Add Secondary Site Collection Administrator to All OneDrive Business User Accounts

To automate the above steps, see Configuring OneDrive for Business Organization for ER 2.0.26.

Once done, see Set OneDrive Business as a Target Location.

Add OneDrive Business User Accounts to a Group

  1. Create a new Microsoft 365 group. This group will be used to hold all Microsoft 365 users with OneDrive Business enabled. Name it "ER2OneDrive" or similar. See Microsoft: Create a group in the Microsoft 365 admin center for more information.
  2. Connect to SharePoint Online using the SharePoint Online Management Shell. Using the Management Shell, get a list of all Microsoft 365 users with OneDrive Business enabled. See Microsoft: Get a list of all user OneDrive URLs in your organization for more information.
  3. Add the list of Microsoft 365 users with OneDrive Business enabled to the "ER2OneDrive" group.

Add Secondary Site Collection Administrator to All OneDrive Business User Accounts

  1. Create a service account to scan OneDrive Business, or use an existing service account. This service account should be assigned Global Administrator permissions.

  2. Add the service account as a secondary administrator for the "My Site" Site Collection on all target OneDrive Business accounts.

    1. Connect to the SharePoint Online Admin Center.
    2. Navigate to user profiles > Manage User Profiles.
    3. Search for a specific user profile and click on Manage site collection owners.
    4. In the site collection owners window, add the service account as the secondary site collection administrator.
    5. Repeat this for all OneDrive for Business accounts.
