If impersonation was not granted, Veeam Backup for Microsoft Office 365 will display an error message when checking organization parameters. Further mailbox processing will not be possible. If impersonation was granted manually using PowerShell with some accounts filtered out ("partial impersonation"), then you will see the corresponding message. If you decide to fully grant impersonation, you can re-run parameters check after granting the impersonation.
