Open a new Exchange PowerShell and see if it connects to Active Directory properly.

1. The configured user account did not have the required privileges (Check the Exchange User Guide).
2. Other backup software was installed (For example, Avamar client or NetWorker client).

1. Configure admin user with the AppAgent Exchange Admin configuration tool if it is not done properly to grant the backup account access permission with the Admin role.
2. Uninstall the other backup software (for example, Avamar or NetWorker) and reboot the host.
