Combine multiple foreach results into a single report - powershell

Question

$results = foreach ($Mailbox in (Get-Mailbox -ResultSize Unlimited))
{
get-MailboxFolderPermission -identity "$($Mailbox.Name):\Calendar" -ErrorAction SilentlyContinue |
Where-Object {$_.User -notlike "Default" -and
$_.User -notlike "Anonymous" -and
$_.AccessRights -notlike "None" -and
$_.AccessRights } |
Select #{N="Mailbox";E={$Mailbox.SamAccountName}}, FolderName, User, AccessRights
}
$results
I am still learning powershell (only 1 full year of experience). I'm using this code to report on calendar permissions for all end user mailboxes in our environment. The code works well but it only reports on the Calendar object. I need to run three separate reports to get the Calendar, Contacts, and Inbox permissions.
I have tried creating an array but it throws multiple values all on one line. (Some end users have more than one person with access to their Calendar/Contacts/Inbox. Does anyone have a good idea of how to combine these results?
thanks
Here is an example of what results I would like:

Answer 1

Iterating Mailboxes only once with an additional
ForEach ($Folder in 'Contents','Calendar','Inbox')
Should be more efficient:
#Date
$date = (Get-Date -f yyyy-MM-dd)
#Pull Permissions
$Permissions = ForEach ($Mailbox in (Get-Mailbox -ResultSize Unlimited )) {
ForEach ($Folder in 'Contents','Calendar','Inbox'){
Get-MailboxFolderPermission -identity "$($Mailbox.Name):\$($Folder)" -ErrorAction SilentlyContinue |
Where-Object {$_.User -notlike "Default" -and $_.User -notlike "Anonymous" -and $_.AccessRights -notlike "None" -and $_.AccessRights } |
Select #{N="Mailbox";E={$Mailbox.SamAccountName}},
#{N="Folder";E={$_.FolderName}},
#{N="User With Access";E={$_.User}},
#{N="Access";E={$_.AccessRights}}
}
}
#Export to Desktop
$Permissions | Sort User | Export-Csv "$env:USERPROFILE\Desktop\ExchangePermissions-$Date.csv" -NoTypeInformation

Answer 2

#Date
$date = (Get-Date -f yyyy-MM-dd)
#Pull Permissions
$Permissions = ForEach ($Mailbox in (Get-Mailbox -ResultSize Unlimited )) {
$userInfo = get-user $Mailbox.name | select Title
ForEach ($Folder in 'Contacts','Calendar','Inbox'){
Get-MailboxFolderPermission -identity "$($Mailbox.Name):\$($Folder)" -ErrorAction SilentlyContinue |
Where-Object {$_.User -notlike "Default" -and $_.User -notlike "Anonymous" -and $_.AccessRights -notlike "None" -and $_.AccessRights } |
Select #{N="Mailbox";E={$Mailbox.SamAccountName}},
#{N="Office";E={$Mailbox.Office}},
#{N="Title";E={$userInfo.Title}},
#{N="Folder";E={$_.FolderName}},
#{N="User With Access";E={$_.User}},
#{N="Access";E={$_.AccessRights}}
}
}
#Export to Desktop
$Permissions | Sort User | Export-Csv
"$env:USERPROFILE\Desktop\ExchangePermissions-$Date.csv" -NoTypeInformation
