Export 365 Users Mailboxes Size and Unit in separate columns

Question

I have good script that export 365 Users Mailboxes Size to csv file.

The results looks like that:

Today it display the Total Size with the Unit (KB/MB/GB) inside the same column.

As for the Total Size (Bytes)- i dont really need that column.

So, i want to separate the Total Size column into 2 separate columns of Size and Unit columns.

Like that:

So at the end, the results will be:

Here's the code:

Param(
    [Parameter(Mandatory = $false)]
    [switch]$MFA,
    [switch]$SharedMBOnly,
    [switch]$UserMBOnly,
    [string]$MBNamesFile,
    [string]$UserName,
    [string]$Password
)

Function Get_MailboxSize{
    $Stats=Get-MailboxStatistics -Identity $UPN
    $IsArchieved=$Stats.IsArchiveMailbox
    $ItemCount=$Stats.ItemCount
    $TotalItemSize=$Stats.TotalItemSize
    $TotalItemSizeinBytes= $TotalItemSize –replace “(.*\()|,| [a-z]*\)”, “”
    $TotalSize=$stats.TotalItemSize.value -replace "\(.*",""
    $DeletedItemCount=$Stats.DeletedItemCount
    $TotalDeletedItemSize=$Stats.TotalDeletedItemSize

    #Export result to csv
    $Result=@{'Display Name'=$DisplayName;'User Principal Name'=$upn;'Mailbox Type'=$MailboxType;'Primary SMTP Address'=$PrimarySMTPAddress;'IsArchieved'=$IsArchieved;'Item Count'=$ItemCount;'Total Size'=$TotalSize;'Total Size (Bytes)'=$TotalItemSizeinBytes;'Deleted Item Count'=$DeletedItemCount;'Deleted Item Size'=$TotalDeletedItemSize;'Issue Warning Quota'=$IssueWarningQuota;'Prohibit Send Quota'=$ProhibitSendQuota;'Prohibit send Receive Quota'=$ProhibitSendReceiveQuota}
    $Results= New-Object PSObject -Property $Result  
    $Results | Select-Object 'Display Name','User Principal Name','Mailbox Type','Primary SMTP Address','Item Count','Total Size','Total Size (Bytes)','IsArchieved','Deleted Item Count','Deleted Item Size','Issue Warning Quota','Prohibit Send Quota','Prohibit Send Receive Quota' | Export-Csv -Path $ExportCSV -Notype -Append 
}

Replace line:

$Results | Select-Object 'Display Name','User Principal Name','Mailbox Type','Primary SMTP Address','Item Count','Total Size','Total Size (Bytes)','IsArchieved','Deleted Item Count','Deleted Item Size','Issue Warning Quota','Prohibit Send Quota','Prohibit Send Receive Quota' | Export-Csv -Path $ExportCSV -Notype -Append

With:

$Results | Select-Object 'Display Name','User Principal Name','Mailbox Type','Primary SMTP Address','Item Count',@{Name = 'Total Size'; Expression = {($_."Total Size").Split(" ")[0]}},@{Name = 'Unit'; Expression = {($_."Total Size").Split(" ")[1]}},'Total Size (Bytes)','IsArchieved','Deleted Item Count','Deleted Item Size','Issue Warning Quota','Prohibit Send Quota','Prohibit Send Receive Quota' | Export-Csv -Path $ExportCSV -Notype -Append

I have replaced 'total size' with the 2 following calculated properties:

@{Name = 'Total Size'; Expression = {($_."Total Size").Split(" ")[0]}}
@{Name = 'Unit'; Expression = {($_."Total Size").Split(" ")[1]}}

This splits the value into an array and will put them into the specified properties of "Total Size" & "Unit"
