PowerShell combining objects

Question

In the following script I am attempting to pull some basic data from Exchange and combine the objects into a single output. I believe the problem is tied to the output assigned to my $Usage variable, as there are going to be multiple results for each database.
I'd also like to sort the data by the "Time In Server" column.
The output I get currently looks like this:
Database     | Display Name | Time In Server
DB01
DB02
DB03
The output I'd like to achieve:
Database     | Display Name | Time In Server
DB01             User 3              250
DB01             User 4              225 
DB03             User 2              190
DB03             User 1              100
# Create a new variable with today's date.
$todaysDate = (Get-Date).tostring("MM-dd-yyyy")
# Retreive a list of mailbox databases
$Databases = (Get-MailboxDatabase | where {$_.Name -like "DB*"} | select Name)
# Create an array to store the output
$Output = @()
# Go through each database and retreive the usage statistics
foreach ($Database in $Databases) {
$Usage = (Get-StoreUsageStatistics -Database $Database.Name | where {$_.TimeInServer -gt "5000"} | Select DisplayName, TimeInServer)
# Create a new object to store this information
$OutputItem = New-Object PSObject;
$OutputItem | Add-Member NoteProperty "Database Name" $Database.Name;
$OutputItem | Add-Member NoteProperty "Display Name" $Usage.DisplayName;
$OutputItem | Add-Member NoteProperty "Time In Server" $Usage.TimeInServer;
# Add the object to our array of output objects
$Output += $OutputItem;
$Output | Export-CSV "$todaysDate.csv" -NoTypeInformation

Hi ImageGuy,
good going so far :).
Your main issue is that you are not handling the possibility of multiple usage cases on a single Database. Here's a rewrite example on how to do this:
# Create a new variable with today's date.
$todaysDate = Get-Date -Format "MM-dd-yyyy"
# Retreive a list of mailbox databases
$Databases = Get-MailboxDatabase | Where-Object { $_.Name -like "DB*" }
# Create an array to store the output
$Output = @()
# Go through each database and retreive the usage statistics
foreach ($Database in $Databases)
# For each usage that exceeds limits
foreach ($Usage in (Get-StoreUsageStatistics -Database $Database.Name | Where-Object { $_.TimeInServer -gt "5000" }))
# Collect information into a hashtable
$Props = @{
"Database Name" = $Database.Name
"Display Name" = $Usage.DisplayName
"Time In Server" = $Usage.TimeInServer
# Add the object to our array of output objects
$Output += New-Object PSObject -Property $Props
$Output | Sort-Object "Time In Server" | Export-CSV "$todaysDate.csv" -NoTypeInformation
Also, as it will only perform the inner loop if at least one case of excessive usage exists, you won't get entries for DBs that do not have anyone using it in excess of limits.
I simplified the object creation a little (though there certainly are other methods that work just as well including your previous one).
Finally, on the last line you see an example for sorting.
Cheers,
Fred
