  • Discovery Management
  • Public Folder Management

Granting Permission for Application Impersonation & Mail Search

This permission allows users added under the Members section of the Discovery Management group (refer to the previous section for setup) to back up and/or restore user item(s) not only for their own account, but also the accounts of other users in the same Members section. To grant permission for this feature, you have to add the Application Impersonation & Mail Search role by following the steps below.

Granting Permission for SharePoint Global Admin

The Global Admin permission allow SharePoint account to list other account’s  Personal Site and OneDrive in the backup source tree. So before using AhsayOBM to create backup set, please ensure the SharePoint account has already owned the permission in order to apply AhsayOBM to back up and/or restore user item(s) not only for their own account, but also the accounts of other users.
