If you are like me and have multiple machines you work on with different profiles, it can be difficult to remember which profile contains which functions. So, I wrote a quick function that will display all the functions for me on start up.

I've always developed and ran scripts locally through VS Code. I'm just getting started with Azure Automation and am not a fan of waiting for the job to complete before seeing my results. In fact, it's very frustrating. I'd rather develop and test my script locally first before running it in Azure Automation.

I'm using a user-managed identity to run scripts against Exchange Online. VS Code has an Azure Automation plugin that provides an option to run script locally, but the script bombs out when attempting to use the user-managed identity, as the user-managed identity may only be run in Azure.

For those of you who use Azure Automation, I can't imagine that you develop significant portions of the script and wait for automation jobs to complete each time to verify changes.

How do you develop locally? Do you use an app registration w/ client secret in key vault and call that from your local machine? Do you have a process for developing locally for scripts that specify managed identities?

Thanks everyone!

Azure Automation Run As Account will retire on September 30, 2023 and will be replaced with Managed Identities. Before that date, you'll need to migrate your runbooks to use managed identities.

However, just the presence of a Run As account doesn’t mean a it is being used. Often these were just created during the automation account provisioning. This script help to determine if you are using the Run As account by search through the runbooks to find references to the Run As Account actually being called. Then finds the last time the runbook was executed. If no date is returned, then the runbook has not executed in the last 30 days.

Enums were introduced to PowerShell in version 5.0 and can be used as a simple way to validate script and parameter input.

Hi everyone, I created this little tool in Rust to generate obfuscated looking glob patterns for paths by utilizing the default environment variables in Windows PowerShell.

You can check it out here: https://github.com/lavafroth/envy-rs

This can probably be used in conjunction with some other tools to bypass AV/EDR.

As you can guess, I'm not a PowerShell ninja. I did not come up with the idea. I learned about it from this video by John Hammond. I merely implemented the code.

  • Function cannot be created because function capacity 4096 has been exceeded for this scope
    I had a long day today when my long-running script (10 hours) gave me weird errors with Microsoft Graph for Teams. Finally, I solved my mistakes and reran the hand to see if the report would be complete this time. Surprisingly, it gave me an error I'd never seen before. "Function cannot be created because function capacity 4096 has been exceeded for this scope". The error is at least weird because it's shown on a production server where I've just a handful of PowerShell modules installed, and I've never seen it on my development machine where I've over 200 modules.

    The TEC 2023 PowerShell Challenge Champion will be known after three rounds of frenetic script coding at The Experts Conference in Atlanta on September 19, 2023. Competitors will need a working knowledge of Microsoft 365 PowerShell, including Exchange Online, Teams, and Azure AD. Being able to think on your feet and come up with working solutions to problems is possibly a more important attribute than coding genius.

I know there are a lot of options out there for DMARC report gathering, but as a project to get used to MSGraph API I wanted to write a script to send a csv report of our DMARC mailbox. It includes calls to our password manager to get the connection info for the application I made to interact with graph. It gives a csv that looks like this

I have seen a lot of calls around Lemmy for more moderation tools. I have been working on Lemmy PowerShell module for a few weeks now, and I went ahead and released a preview version with multiple moderation tools now available. The module has the ability to perform the following tasks using a simple command line tool:

  • Search posts and comments
  • Remove a post
  • Remove a comment
  • Lock and unlock posts
  • Add and remove moderators
  • Create new posts and comments

You can get started now by installing the module through the PowerShell gallery.

Install-Module Lemmy-preview
Import-Module Lemmy-preview

If you are not familiar with PowerShell, I've include detailed instruction in the GitHub repo with lots of example. https://github.com/mdowst/Lemmy-PowerShell

If you run into any issues please let me know either here or by submitting an Issue to the repo.

What happens to PowerShell scripts using Azure AD, Azure AD-Preview, or MS Online modules on June 30, 2023?

There will be no impact to PowerShell scripts using these legacy modules on or after June 30, 2023. They will continue to function and be supported until deprecation announcement.

What happens to PowerShell scripts using Azure AD, Azure AD-Preview, or MS Online modules after March 30, 2024?

We plan to deprecate Azure AD, Azure AD-Preview, and MS Online PowerShell modules on March 30, 2024. After this date, the only support offered for these PowerShell modules will be support in migrating to Microsoft Graph PowerShell SDK. Only security fixes will be offered for these PowerShell modules after deprecation is announced. Once these modules are deprecated, they will continue to work for a minimum of six (6) months before being retired.

I've been writing PowerShell code for almost 10 years now, and I love it when I come across someone who uses interesting techniques and patterns that I haven't seen before.

Do any of you have a list of users in the community from which you've taken inspiration in your own code? Who are they? I'd like to follow them :-)

PowerShell Weekly is a hand curated list of PowerShell news, blogs, scripts, etc. that I discover each week and feel are worth passing on. In other words it is not just me reporting everything with a PowerShell hashtag.

There is nothing to sign-up for and there are no ads. It's just my little way of giving back to the community. I also do not accept any sponsored content, but I do take recommendations and suggestions from the community, so feel free to send things my way.

I try to get it published by 9 am US central time (2 pm UTC) each and every Friday. (Expect for the week between Christmas and New Years, I give myself that week off)

It has been going strong for 4 years now and the entire back catalog is searchable and tagged with categories, authors, and timeframes.
