Automatically Schedule Microsoft Teams Do Not Disturb Presence Based on Outlook Calendar Events

Automatically Schedule Microsoft Teams Do Not Disturb Presence Based on Outlook Calendar Events

Comments 1 comment

In this article I will be showing you how you can automatically have Microsoft Teams set its presence to Do Not Disturb, or any other presence, based on events in your Outlook Calendar. I also looked into leveraging Power Automate but it began to require premium connectors and at that cost, going the serverless automation route was much cheaper.

An overview of this automation is as follows:

  1. Run on a set schedule.
  2. Get all users within the tenant, if the user does not have a mailbox, proceed to the next user, if the user does have a mailbox proceed to the next step.
  3. Get the users events that will occur within the next 1 hour (configurable value)
  4. See if there is an event that matches what we are looking for. In my instance, if an event title/subject is “DND” (not case-sensitive) then proceed to the next step, otherwise go to

Automated Alerts on Azure (Entra ID) Application Secret Expirations

Automated Alerts on Azure (Entra ID) Application Secret Expirations

Comments 42 comments

Monitoring Azure AD (Entra ID now) application secret expirations in an enterprise is a critical aspect of maintaining robust security and ensuring uninterrupted service. When application secrets expire without timely renewal, it can disrupt business operations by causing application failures. Proactive management of application secret expirations helps enterprises avoid last-minute issues, enabling a more secure and efficient operational environment.

During my brief research in finding an automated approach to monitoring application secret expirations, I found multiple write-ups and articles but many only showed the code on how to get the expiration property without walking through setting up the automation itself. Another issue was not converting the default UTC time to local time to get more accurate expiration datetimes, and also dealing with applications with multiple secrets that expire at different times.

This article will walk one through the code’s logic, including converting time and dealing with multiple values, and creating … Continue...

The Microsoft Graph Command-Line Interface (CLI)

The Microsoft Graph Command-Line Interface (CLI)

On November 22nd, Microsoft announced that the Microsoft Graph CLI was now generally available at version 1.0.0. The command-line tool provides convenient methods to access Microsoft Graph API capabilities on any operating system and any shell. The CLI uses the Microsoft Graph v1.0 endpoint. Microsoft does provide a Beta CLI that interacts with the Microsoft Graph Beta endpoint.

The CLI not only allows you to get objects but update, create and delete objects using the Microsoft Graph REST API.

Download the CLI

MacOS

Download the CLI from here.

  • If you have an ARM based Mac (M1, M2, etc) computer, download the msgraph-beta-cli-osx-arm64... package.
  • If you have an Intel processor, download the msgraph-beta-cli-osx-x64... package.

Extract the files to a directory you can reference later. For my purposes, I created a folder called, ‘MSGraph CLI’ in my Home Directory.

Next, we will update PATH permanently by editing your shell profile (… Continue...

Microsoft Graph API Endpoint Adds Last Successful Sign-In Date Time

Microsoft Graph API Endpoint Adds Last Successful Sign-In Date Time

Comments 3 comments

Previously, if you wanted to find a user’s last successful sign-in to your Microsoft 365 tenant using the Microsoft Graph REST API, you would have to iterate through Entra ID sign-in logs. With new recent additions to the Microsoft Graph API Beta Endpoint, you can now return the UTC value just by parsing the user details and properties. The Microsoft documentation regarding the signInActivity resource type can be found here.

LastSignInDateTime vs LastSuccessfulSignInDateTime

The difference between lastSignInDateTime and lastSuccessfulSignInDateTime property is:

  • lastSignInDateTime: The last interactive sign-in date and time for a specific user. You can use this field to calculate the last time a user attempted to sign into the directory the directory with an interactive authentication method. This field can be used to build reports, such as inactive users. The timestamp represents date and time information using ISO 8601 format and is always in UTC time. For

Centrally Manage Company Contacts and Deploy to Built-In Contacts App Using Intune, SharePoint, PowerShell and Graph API.

I recently met with a company that was looking for a better way to get contacts to their employee’s work phones. Currently, they are sending a .vcf file and then having the employees manually save the contacts. While this works, the problem is if you need to send a new contact, you now need to send a new .vcf file to every employee and instruct them on how to save it. Similarly, if you ever need to remove a contact, you need to instruct your employees to manually delete that contact.

One of the first things I thought about, is creating an App Configuration Policy to force Outlook to sync contacts to native apps. Most of the contacts I need to sync to the phone were employees of the company so I figured it would sync from the Global Address List and then maybe I could create contacts in … 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.
