Step 15. Add Veeam ONE Service Account to Veeam ONE Administrators Group
When Veeam ONE installation completes, the installer will prompt you to perform the logoff and logon procedure to create new user groups that will be used to accommodate user accounts for accessing Veeam ONE locally and remotely.
Check that the Veeam ONE service account is included in the Veeam ONE Administrators user group. If this account is not a member of the Veeam ONE Administrators user group, add it to the group manually.
For details on Veeam ONE user groups, see Security Groups.
