Listing Outlook mailbox rules for all users

June 25, 2014 | Technical Solutions

Does your company use Outlook email forwarding? As your organisation has grown, have the rules become hard to manage?

We have a customer using Exchange Server for a few dozen users. They use mailbox rules so they can delegate various activities when staff are out of the office. Occasionally they lose track of what’s being forwarded, and it’s a pain to get this information from each user one by one. Here’s a little PowerShell script I threw together to automate it. I ran this on their server from the “Exchange Management Shell”. It’s my first PowerShell script ever; I’m used to Linux shell scripts and up till now haven’t made complex scripts under Windows. That may change:

PowerShell Script to list Outlook mailbox rules for users in an organisation

$users = get-mailbox

ForEach ($user in $users)
{
        $rules = get-InboxRule -Mailbox $user.name
        if ($rules.length -gt 0) {
                echo ""
                echo $user.name
                echo ""
                $rules | select name, priority, description | fl
                echo ""
        }
}

Save this in a file with the extension “ps1” (that’s a one on the end) and run it from PowerShell to get the output – use > to redirect to a file if necessary. If you put the script in the current directory, you may need to explicitly specify the path, for example: .\run.ps1 > rules.txt Note that this only shows the server-side rules, such as placing messages in a folder, forwarding, etc. Anything that interacts with the client machine such as a popup will not appear in this report – this suits our customer because they want the rules to work when a user is not even logged in. The customer is pleased they can see the server-side rules in one report, and I’ve learned that it’s not just Linux that can support powerful scripting!

    Thanks for your script above. It was very useful. By any chance do you have something similar that would work for Public Folders?
    Thanks,

    can you help with a means to search all email mailbox rules and look for a specific set of words in the body or subject
