If you have multiple Front-End servers, your account will be randomly homed to one of them, and it’s not revealed if you just
get-csuser. You need to
Get-CsUserPoolInfo <username>. This won’t spell it out for you, but you should be able to figure out which FE is which.
Get-CsUserPoolInfo <username> | Select-Object -Expand PrimaryPoolMachinesInPreferredOrder will ID the server, down to its FQDN. I’m yet to find a way I can move a user to a different Front-End. Call me fussy, but I always like to have MY account on the first FE.
The other way to find the home server’s much more painful. If you
get-csuser <username> | fl * it dumps EVERYTHING.
Piping to “fl *” will often reveal hidden information you didn’t even know was there. Try it sometime!
