The Last backup parameter is displayed in the job sessions history while should be hidden from the job results.

Upgrading to version 5b

If you're running a previous version of Veeam Backup for Microsoft Office 365 and want to be prepared for the release of Veeam Backup & Replication v11 and Veeam Cloud Connect v11, now is a great time to upgrade to the updated version. You can simply upgrade to version 5b from versions 3.0 (build 3.0.0.422) and upwards.

However, upgrade from the beta version of Veeam Backup for Microsoft Office 365 5.0 are not supported. Additionally, Veeam Backup for Microsoft Office 365 5b is not applicable to installations of Veeam Backup for Microsoft Office 365 on top of Veeam Backup & Replication 9.5 Update 4, 4a, or 4b and Veeam Cloud Connect 9.5 Update 4, 4a, or 4b.
