Enable Teams Graph API Backup on Proxies
Note: Enabling Teams Graph API Backup for a proxy is irreversible. Once a proxy has been configured to use the Microsoft Graph Export API for Teams, it cannot be reverted to use EWS.
On the Veeam Backup for Microsoft 365 server, in an Administrative PowerShell window*, perform the following steps to enable usage of the Graph Export API for Teams on each of the Proxies that will use the new API to backup Teams Chats.
*Alternatively, right-click the Veeam Backup for Microsoft 365 PowerShell shortcut on the desktop and select Run as Administrator.
- Run the following PowerShell Command to retrieve a list of all available Proxies and their Proxy IDs.
You will need the proxy IDs for the next step.
