To communicate with proxy servers, Veeam uses the proprietary component — Veeam Backup Proxy for Microsoft Office 365 Service that is installed on a proxy machine during adding a new backup proxy server. If this component becomes outdated, you will need to upgrade it.
To upgrade the component, do the following:
- Go to the Backup Infrastructure view.
- In the preview pane, select a proxy server you want to upgrade and on the ribbon menu, or using the corresponding context menu command, click Upgrade.
To upgrade all proxy servers simultaneously, select the Backup Proxies node and click Upgrade.
- Select a proxy to upgrade. You can select multiple proxies at the same time.
- Specify user credentials to access the server. The account must be a member of the Local Administrator group on a target server.
Once the upgrade procedure is complete, you will be notified about the results.
