They keep trying to brute force a login. I block them after too many attempts but they just switch to a different IP in the same address range assigned to MS Virtual Desktop.
As explained in the original post, blocking an individual IP is ineffective and blocking the entire range is impractical because other legitimate customers use Virtual Desktop too.
