I was trying to upgrade VBO 365 from V3 to V4, everything looks fine except upgrading Default Backup Repository, the status shows Upgrade failed “Access is denied”, it has never happed with other customers for upgrading VBO 365 from V3 to V4.

I checked the logs from C:\ProgramData\Veeam\Backup365\Logs and found a warning and error, they show “Warning: Authorization denied. Identity: ENG\VEEAM01$ (expected: WORKGROUP\VEEAM01$)” and “Error: Access is denied”, I recall my memory, we have the Backups for VBR and VBO at the same server, the server was non-join domain, it was an issues for settings VBO Backup Proxy Servers, because “A server with Veeam Backup for Microsoft Office 365 and backup proxy servers must be deployed within the same or a trusted domain” (check the detail from https://helpcenter.veeam.com/archive/vbo365/30/guide/vbo_backup_proxy_servers.html ), so I join the server to domain after installed VBO 365 V3, this is the root cause. The server name (or join domain) cannot be change after install VBO 365, because the register account won’t change at VBO 365 configuration after you change server name and it will happen access denied error when you upgrade it.
