Overview

When OneDrive Business is added as a scan Target, ER2 returns all Microsoft 365 groups and user accounts in each group. You can select specific groups or individual users when setting up the scan schedule, and each group will be presented as a separate location for the OneDrive Business Target.

Example of OneDrive Business structure: OneDrive Business [domain: example.onmicrosoft.com] +- Exchange Online on target MSONE:EXAMPLE.ONMICROSOFT.COM +- Group Engineering +- Group Design

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.

Edit OneDrive Business Target Path

1. Set Up and Scan a OneDrive Business Target.
2. In the Select Locations section, select your OneDrive Business Target location and click Edit.

3. In the Edit OneDrive Business dialog box, enter a (case sensitive) Path to scan. Use the following syntax:

   Folder to Scan	Path
   All user accounts in a specific group	Syntax: <Group Display Name> Example: Engineering (SG)
   Specific user account in group	Syntax: <Group Display Name>/<User Principal Name> Example: Engineering (SG)/user1@example.onmicrosoft.com
   Specific folder for user account in group	Syntax: <Group Display Name>/<User Principal Name>/<Folder> Example: Engineering (SG)/user1@example.onmicrosoft.com/ProjectA
   Specific file for user account in group	Syntax: <Group Display Name>/<User Principal Name>/<Folder>/<File> Example: Engineering (SG)/user1@example.onmicrosoft.com/ProjectA/example.html

   If there are multiple Microsoft 365 groups with the same display name in your domain, ER2 will only retrieve the first group occurrence. For example, if there are three groups with the same display name, "Engineering", ER2 will only probe, scan and return results for the first "Engineering" group for the OneDrive Business Target.
4. Click Test and then Commit to save the path to the Target location.

User Account in Multiple Groups

A OneDrive Business-enabled user account that belongs to multiple groups

• is scanned each time a group the user belongs to is scanned.
• consumes only 1x data allowance usage regardless of how many times it is scanned as part of different groups.
