get-mailbox |  ? {$_.customattribute3} | sort customattribute3 | ft name,customattribute3

get-mailbox |  ? {$_.customattribute7} | sort customattribute7 | ft name,customattribute7
get-mailbox |  ? {$_.customattribute8} | sort customattribute8 | ft name,customattribute8
get-mailbox |  ? {$_.customattribute9} | sort customattribute9 | ft name,customattribute9
get-mailbox |  ? {$_.customattribute10} | sort customattribute10 | ft name,customattribute10
get-mailbox |  ? {$_.customattribute11} | sort customattribute11 | ft name,customattribute11
get-mailbox |  ? {$_.customattribute12} | sort customattribute12 | ft name,customattribute12
get-mailbox |  ? {$_.customattribute13} | sort customattribute13 | ft name,customattribute13
get-mailbox |  ? {$_.customattribute14} | sort customattribute14 | ft name,customattribute14
get-mailbox |  ? {$_.customattribute15} | sort customattribute15 | ft name,customattribute15
