On 4.1, I was able to view the number of users per server via Blackberry Manager > Servers. This would display each server and Number of Users.
On 5.0, I'm not able to find such a screen. in BAS, I select Manage Users > Blackberry Enterprise Server > (server name) > Search. Get the number of users, then repeat for each server.
Is there 'one' screen that will list all servers and number of users per server?
