Powershell formatting text output to e-mail

This is a very basic and simple Powershell question, but I'm not sure what terms to search on and my MS Powershell book doesn't cover the topic.  Sorry I'm very much a Powershell newbie.

I want to format e-mails so they say something like:

Dear X, your Outbox folder is currently Y MB is size.  Please review.

The problem I'm getting is the variables are coming out like @{Name=X} @{$_.FolderAndSubFolderSize.ToMB()=Y

I know this must be the most basic of formatting questions, or I'm just not approaching it right.  Any suggestions?  Sample from the script and how I'm trying to extract the variable:

Add-PSSnapin Microsoft.Exchange.Management.PowerShell.Admin
foreach($mailbox in get-mailbox) {
      foreach($outbox in (Get-MailboxFolderStatistics -identity $mailbox -FolderScope Outbox | where {$_.FolderType -ne "User Created" -and $_.FolderAndSubfolderSize -gt 20000000})) {
            $name = $mailbox | select Name -last 1
            $folder = $outbox | select Identity
            $foldersize = $outbox | select {$_.FolderAndSubfolderSize.ToMB()}
            write-host "$name $foldersize"

try debug the script in PowerGui script editor and check the properties of $name and $foldersize.
it support intellisense so while debug you can dig in and view the object properties.

Looks like the % is key to just pulling the value, so should give me something to google.  So the following seems to work, I guess I just need to find out why (and buy a better book).

Add-PSSnapin Microsoft.Exchange.Management.PowerShell.Admin

foreach($mailbox in get-mailbox) {
      foreach($outbox in (Get-MailboxFolderStatistics -identity $mailbox -FolderScope Outbox | where {$_.FolderType -ne "User Created" -and $_.FolderAndSubfolderSize -gt 20000000})) {
            $name = %{$mailbox.Name}
            $folder = $outbox | select Identity
            $foldersize = %{$outbox.FolderAndSubfolderSize.ToMB()}
            write-host "$name $foldersize"
An expression like this:
$yourcomplexobject | select-object oneproperty

creates a simple object from the complex one, but it is still an object, with one property. Converting an object to a string - which you did when you used write-host - is a risky operation, because you can not always predict what will happen, how the string will look like. In your case you got that string in the @{...} form.

To make PowerShell's life easy you should help him by creating the string or some other raw data type to write-host. What I did is:

$yourcomplexobject | foreach-object {$_.oneproperty.withsomemethod()}

(% is the alias for foreach-object) I selected the VALUE of the result of the method of the property, which was a number (raw data type), so there was no problem with converting it to a string.

And I also did:
$yourcomplexobject | select-object -expandproperty oneproperty

Which has very similar result to
$yourcomplexobject | %{$_.oneproperty }

With the expandproperty parameter select-object "grabs" the selected property to one level higher, so it is now not just a property of an object but THE object. If it is a string, there is no problem writing it to the console.
Thanks for the additional information, this is what I assumed was happening.  From my very limited experience I think the object concept works really well in PowerShell.  Just being able to query one field without having to try and parse the information out is pretty good.  I'd randomly tried {$_.oneproperty.value} and $object.oneproperty.value to see if it works, but obviously not.  All queries on Google had come back with formating the text for console (fl, ft etc) and not returning just the value of a property.

I'd tried the -expandproperty but it didn't work, returning error messages.  But the % works perfectly.  Thanks again for your help.
select-object -expandproperty works really on properties, not on methods called on properties...
