Post Notifications About Unused Office 365 Licenses to Teams using Azure Runbooks

Comments 0 Comment

I have written several articles on using PowerShell to send alerts and notifications to Microsoft Teams, but up until now they were set up using only the task scheduler. As more and more companies move to the cloud I wanted to see how I could do cloud infrastructure alerting as well. In this article I am using an Azure RunBook to connect to my Office 365 tenant, parse my licenses, and return any that need reconciliation. If you get your Office 365 licenses from a CSP or any other kind of reseller, you may get charged for all of your licenses, applied or not. So it’s a good thing to make sure you don’t have any extra ones lying around.

I created a script that you can just change the variables for and it will create the following … Continue...

ChatOps: Setting up PoshBot for Microsoft Teams

ChatOps: Setting up PoshBot for Microsoft Teams

Comments 6 comments

PoshBot is a chat bot written in PowerShell and created by DevBlackOps. ‘It makes extensive use of classes introduced in PowerShell 5.0. PowerShell modules are loaded into PoshBot and instantly become available as bot commands.’1 PoshBot can do pretty much anything you configure it to do. You can have it create Azure servers, reset Active Directory passwords, create and modify help desk tickets, license Office 365 users, etc. ‘If you can write it in PowerShell, PoshBot can execute it.’1 

Important: PoshBot has some great documentation, make sure you bookmark and review it.

In this guide I will walk you through setting up PoshBot for Microsoft Teams. It’s a little more tedious than Slack (which is a few commands) but once you get it going it works flawless. Keep an eye out as I will be publishing more articles on different PoshBot plugins that I create which … Continue...

Find Un-Migrated Phone Numbers in Cisco Call Manager to Port to Skype for Business / Teams

Comments 0 Comment

Currently I am doing a Skype for Business migration for a large enterprise. The current phone system is Cisco Call Manager and I am migrating everything to Skype for Business / Microsoft Teams in Office 365. I am at a point where I have migrated a majority of my local users but I want to make sure I grab all available phone numbers I can. These phone numbers could be left from old users, systems, etc.

ImportExcel PowerShell Module

To make this work easier, I am going to be using the ImportExcel PowerShell module. I could use Export-CSV but then I will end up with several CSV data files to work with, and it can get confusing quick. Installing the module is easy as it is available on the PSGallery.

Get a Teams Notification the Moment an Active Directory User gets Locked Out with PowerShell Using Webhooks

Get a Teams Notification the Moment an Active Directory User gets Locked Out with PowerShell Using Webhooks

Comments 25 comments

I have been recently using Teams as a central location for my organizations technical notifications instead of email as it provides a way for an entire Help Desk team to openly collaborate on the message and its contents. I recently got a request to get a Teams notification when a user gets locked out of their Active Directory account. By setting up a Webhook connector we can make it happen. The script will be triggered from Task Scheduler on Event ID 4740 which is created when a user gets locked out. By using “Search-ADAccount -LockedOut” we can return an array of locked out accounts, but by ordering it by lockout time we can ensure that we grab the most recent locked out user that corresponds to the security event.

I set the script and scheduled task up on my PDC because as far as I know, the actual lockout event … Continue...

In my previous post I went through setting up a Team’s webhook to send a daily message / notification of all your Active Directory users that have their password expiring in a week or less. This is valuable for an IT team as they can review users and work together on the within the same work space (team). In this post I will be setting up another scheduled task to send a daily message on Active Directory accounts that have not logged on in 90 days or more. I am also returning attributes like LockedOut, LastLogon, Enabled and more. The array of users is sorted, showing the users that have not logged on in the longest to the shortest. You can change the sort order to fit the needs of your environment. By using the cmdlet, “New-Timespan” I can get the amount of days since the user last logged on.… Continue...

Post Users with Expiring Passwords as Microsoft Teams Message with PowerShell

Microsoft Teams has many connectors available including Incoming Webhook. “This provides an easy solution to post notifications / messages from any scripting language through JSON formatted web service call.”1

In this post I will show you how you can gather all of your users who have passwords expiring within a specified time range, and send a notification including all relevant information to a Teams Channel. In my example I will get all users who have passwords expiring in 7 days and less and have it notify my “Help Desk” Teams Channel.  

The current script will parse only enabled users because we don’t need to report on users, ‘passwordlastset’ attribute if the account isn’t even allowed to log in. It will also sort all of our data, so the users with passwords expiring the earliest will always be at the top of the message. The top description under, “Users … Continue...
