ChatOps: Setting up PoshBot for Microsoft Teams

ChatOps: Setting up PoshBot for Microsoft Teams

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.’

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...

Connect and Navigate the Microsoft Graph API with PowerShell

Connect and Navigate the Microsoft Graph API with PowerShell

Graph is Microsoft’s RESTful API that allows you to interface directly with Azure AD, Office 365, Intune, SharePoint, Teams, OneNote, and a whole lot more. By using the Invoke-RestMethod PowerShell cmdlet we can connect and interact directly with the Graph API. The Invoke-RestMethod cmdlet sends HTTP and HTTPS requests to Representational State Transfer (REST) web services that returns richly structured data. PowerShell formats the response based on the data type. For an RSS or ATOM feed, PowerShell returns the Item or Entry XML nodes. For JavaScript Object Notation (JSON) or XML, PowerShell converts (or deserializes) the content into objects.1 In this article, I will walk you through setting up the Azure Application, assigning proper  permissions, Authentication and finally running queries against the Graph API. Once you understand how to properly authenticate and format queries you will see how powerful Graph can be for you and your organization.

PowerShell Function to Connect to All Office 365 Services With Support for MFA

PowerShell Function to Connect to All Office 365 Services With Support for MFA

I usually have to connect to Office 365 via PowerShell at least once per day. I had the following function stored in my PowerShell Profile:

This allowed me to just open PowerShell and type Connect-O365 to connect to Office 365 instead of looking up the Session information and all of the cmdlets needed. One of the issues I faced was the lack of multi-factor authentication support. To connect to Exchange Online or Security and Compliance Center using multi-factor authentication you must use another module that is found in your tenant. Also, … Continue...

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

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...

Post Inactive Users as a Microsoft Teams Message with PowerShell

Post Inactive Users as a Microsoft Teams Message with PowerShell

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

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...

Sync Office 365 / AzureAD down to ADDS

Sync Office 365 / AzureAD down to ADDS

I recently found myself needing to build out an on premise Active Directory environment and populate it from objects found in Office 365 (AzureAD). The local Active Directory would then be configured as the identity source and would sync up to AzureAD using Azure AD Connect. Unfortunately, Azure AD Connect is currently a one way sync from your on premise Active Directory Domain Services environment to AzureAD and wont sync objects down. AADConnect does have the ability to match our AzureAD objects to their corresponding Active Directory objects but, if an attribute like City, Phone Number, Department, Title, etc. is present in your existing AzureAD and not in ADDS, the attribute may remain in AzureAD but not replicate down to ADDS. So we will want to copy over as many attributes from AzureAD to our local Active Directory as possible in preparation for the Azure AD Connect sync. We will … Continue...

Configure and Deploy Intune MDM

Configure and Deploy Intune MDM

Description

In this article I will be configuring and deploying Intune as a stand-alone MDM solution. This article will walk you through deploying applications to devices, configuring your Company Portal, enrolling end user devices, creating policies and more.

Solution

Configure MDM Authority

  1. First we must configure Intune as my MDM authority. Since I am doing a stand alone I want Intune as the only authority and not Configuration Manager. By logging into portal.azure.com I can expand the Itune node and select “Device Enrollment”
  2. Select  “Intune MDM Authority” and then click “Choose”
  3. I will get a notification that my changes were saved successfully

Configure APN Certificate
