How to manage Enterprise environments
Part 2 - Creating PowerShell scripts with a Filtered query

Previously -

In my previous tutorials I have showed how to create basic PowerShell scripts using the import-csv and export-csv functionalities.

This knowledge will help you create scripts for your daily reports and administration.
However sometimes, due to the size and complexity of your organization, you may need to create a filtered query to help refine your target. The best way to do this is to create a PowerShell script that uses a filtered query.

There are countless 'queries' that you can perform using this method and I will run through a few options which will help you manage what sometimes may look unmanageable. The following examples will provide inspiration on how you can create filtered queries for your day to day management.

----------------------------------------------------------------------------------------------

Example 1 - 
Filtered Query using Custom Attributes -
Get-Mailbox -ResultSize "unlimited" -Filter {CustomAttribute1 -eq "Managed Account"} |
Get-MailboxStatistics |
Select DisplayName,Database,DatabaseName,ServerName,ItemCount,TotalItemSize,AttachmentTableTotalSize |
export-csv -NoTypeInformation c:\scripts\MailboxStatistics-ManagedAccounts.csv

Below is the csv file that is generated.




----------------------------------------------------------------------------------------------

Example 2 - 
Filtered Query using Mailbox Type -
Get-Mailbox -ResultSize "unlimited" -Filter {RecipientTypeDetails -eq "SharedMailbox"} |
Get-MailboxStatistics |
Select DisplayName,Database,DatabaseName,ServerName,ItemCount,TotalItemSize,AttachmentTableTotalSize |
export-csv -NoTypeInformation c:\scripts\MailboxStatistics-SharedMailboxes.csv

Below is the csv file that is generated.





-----------------------------------------------------------------------------------------------

Example 3 - 
Filtered Query using Active Directory / Exchange Attribute -
Get-Mailbox -ResultSize "unlimited" -Filter {Office -eq "Singapore"} |
Get-MailboxStatistics |
Select DisplayName,Database,DatabaseName,ServerName,ItemCount,TotalItemSize,AttachmentTableTotalSize |
export-csv -NoTypeInformation c:\scripts\MailboxStatistics-SingaporeOffice.csv

Below is the csv file that is generated
