Update Get-MessageTrackingReport.md

When you do something like:


$Temp = Search-MessageTrackingReport -Identity "Jane" -Recipients [email protected] -TraceLevel High

You are storing several instances in the $Temp variable (which means $Temp is essentially a collection). 

When running this next command:

Get-MessageTrackingReport -Identity $Temp.MessageTrackingReportID -ReportTemplate Summary -Status Delivered

You're providing multiple MessageTrackingReportIds at once—but this particular cmdlet expects just one identity at a time. 

Hence, you receive an error saying PowerShell couldn't transform an ArrayList into an expected single identity.

Solution:

Handle this using a loop, iterating over each MessageTrackingReportId one-by-one. Here's an easy method:

# Loop through each MessageTrackingReportId stored in $Temp and retrieve detailed tracking report summary

foreach ($reportId in $Temp.MessageTrackingReportId) {
    Get-MessageTrackingReport -Identity $reportId -ReportTemplate Summary -Status Delivered
}
