I've installed Exchange 2013 SP1 (current patch level). I'm tying to install the Exchange Plug-in per vmware-data-protection-administration-guide-60.pdf, age 169. VMware VDP Exchange Backup User Configuration Tool start and tells me "Current user is not a Domain Administrator" (see screen shot). I'm logged into the machine using a Domain Administrator credentials, not the local machine. The Exchange sever, Storage group, Mailbox store dropdowns are empty, apparently from an authority problem.
The KB Creating a VMware vSphere Data Protection (VDP) backup user account for exchange plugin with VDP Advanced (2073168) talks about creating a VDPBackupUser account manually. Before I trot down this road, I thought I'd see if there is something obvious or basic that I have missed.
