Interesting! I used below trick in mine and it produces same result as yours. The crazy part is I search everywhere for something like this before I decided to resolve it myself.

-------------------------------

$stats = $mb | Get-MailboxStatistics | Select-Object TotalItemSize,ItemCount,LastLogonTime,StorageLimitStatus,TotalDeletedItemSize

$lastlogon = $stats.LastLogonTime

$TotalItemSize = [double]$Stats.TotalItemSize.SubString($Stats.TotalItemSize.indexof("(")+1, $Stats.TotalItemSize.indexof(" b")-$Stats.TotalItemSize.indexof("("))

$TotalItemSizeGB = $TotalItemSize / 1073741824

$TotalItemSizeGB = "{0:N2}" -f $TotalItemSizeGB

$TotalItemSizeMB = $TotalItemSize /1048576

$TotalItemSizeMB = "{0:N0}" -f $TotalItemSizeMB
