When attempting to execute Veeam PowerShell commands, the following error occurs: Unable to connect to the server with MFA-enabled user account.
This error occurs when MFA (Multi-Factor Authentication) is enabled within Veeam Backup & Replication and the account you are logged in as is not designated as a service account. As noted in the MFA Requirements and Limitations: MFA is not supported for PowerShell (either interactive logon or non-interactive connections). To use PowerShell cmdlets with Veeam Backup PowerShell Module or Microsoft Windows PowerShell, run the Veeam Backup & Replication console or Microsoft Windows PowerShell under the service account with disabled MFA.
To enable the execution of PowerShell commands, either run PowerShell as a dedicated service account (see note below) or disable MFA for your account by temporarily assigning it as a service account. Note: Once a user has been marked as a service account, MFA is not disabled until the Edit User and Users & Roles windows are closed by clicking OK. The PowerShell window does not need to be reopened if it was open before the change. If you temporarily mark a user as a service account, remember to remove that user's service account status to restore MFA requirements after executing the PowerShell commands. Some PowerShell scripts may not operate correctly when launching PowerShell using the "Run as different user" feature, and require further troubleshooting.
