In a Windows environment, particularly when dealing with Microsoft Exchange Server, administrators often need to manage mailbox data. One common task is exporting mailbox data to PST files. After initiating an export request, it's crucial to monitor the progress and status of these requests. This is where the Get-MailboxExportRequestStatistics cmdlet comes into play.

The Get-MailboxExportRequestStatistics cmdlet is used in Exchange Management Shell (EMS) to retrieve detailed information about mailbox export requests. This cmdlet provides insights into the status, progress, and any errors associated with the export process.

Examples:

Example 1: Retrieve Statistics for a Specific Mailbox Export Request

To get the statistics for a specific mailbox export request, you need to know the identity of the request. Here’s how you can do it:

Get-MailboxExportRequestStatistics -Identity "MailboxExportRequest1"

This command retrieves the statistics for the export request named "MailboxExportRequest1".

Example 2: Retrieve Statistics for All Mailbox Export Requests

If you want to get the statistics for all mailbox export requests, you can use the following command:

Get-MailboxExportRequest | Get-MailboxExportRequestStatistics

This command first retrieves all mailbox export requests and then pipes them to Get-MailboxExportRequestStatistics to get their statistics.

Example 3: Retrieve Detailed Statistics for a Mailbox Export Request

For more detailed statistics, including the number of items processed and the size of the data, you can use the -IncludeReport parameter:

Get-MailboxExportRequestStatistics -Identity "MailboxExportRequest1" -IncludeReport

This command provides a detailed report on the export request named "MailboxExportRequest1".

Example 4: Export Statistics to a CSV File

To export the statistics of all mailbox export requests to a CSV file for further analysis, you can use the following command:

Get-MailboxExportRequest | Get-MailboxExportRequestStatistics | Export-Csv -Path "C:\ExportRequestsStatistics.csv" -NoTypeInformation

This command retrieves all mailbox export requests, gets their statistics, and exports the data to a CSV file located at "C:\ExportRequestsStatistics.csv".

Understanding the Output

The output of Get-MailboxExportRequestStatistics includes several important pieces of information:

• Status: Indicates the current status of the export request (e.g., InProgress, Completed, Failed).
• PercentComplete: Shows the completion percentage of the export request.
• BytesTransferred: Indicates the amount of data transferred so far.
• ItemsTransferred: Shows the number of items transferred so far.
• FailureCode and FailureMessage: Provide details if the request has failed.

Conclusion

The Get-MailboxExportRequestStatistics cmdlet is a powerful tool for Exchange administrators to monitor and manage mailbox export requests. By using this cmdlet, you can ensure that your export processes are running smoothly and address any issues promptly.
