Connect to the Microsoft Graph API with PowerShell

March 20, 2018 Brad Wyatt Comments 0 Comment

This article will show you how to work with the Graph API using a PowerShell module. If you want to learn how to work with the API with only PowerShell please visit this article: https://www.thelazyadministrator.com/2019/07/22/connect-and-navigate-the-microsoft-graph-api-with-powershell/

The Microsoft Graph API is a REST API provided by Microsoft for integrating and managing Office 365 Exchange Online, OneDrive for Business, and Azure AD. It allows for application developers to integrate their apps with those Microsoft Services. Management of the environment is also possible but requires understanding of OAuth and REST.¹

By using the PowerShell module PSMSGraph we can interact with the Graph API in a more PowerShell friendly way. The MSMSGraph module is an API wrapper. It seeks to take the “foreign” concepts of REST and OAuth and make them accessible and usable in PowerShell. This module strives to make PowerShell administration and automation tasks via the Microsoft Graph API more like … Continue...

Remotely Install Office ProPlus / Update Office Configuration on Client Computers with PowerShell

March 20, 2018 Brad Wyatt Comments 2 comments

There are some immediate perks for using PowerShell to either install an application on remote computers or update an applications configuration remotely. In this post I will do several things, Install Office 365 ProPlus to a remote computer, and update the configuration of Office 365 ProPlus on the remote machine, having it go from the Monthly channel to the Semi-Annual channel and also removing groove.exe and lync.exe (Skype for Business).

When updating the configuration the install is silent and the EULA is accepted by setting <Display Level=“None” AcceptEULA=“TRUE”/>. When you set FORCEAPPSHUTDOWN to false, Office applications can be used during the upgrade but its recommended to restart the client workstation at the end of the install. I have also seen it not able to update if certain office applications are running. It’s recommended to set FORCEAPPSHUTDOWN to TRUE to close the office applications while … Continue...

Get Friendly License Name for all Users in Office 365 Using PowerShell

March 19, 2018 Brad Wyatt Comments 42 comments

When you want to look up a users license in Office 365 using PowerShell you are presented with a unfriendly Sku. Sometimes the Sku and the actual license name are similar but sometime it’s hard to distinguish the name from the Sku.

Using a hash table we can convert the Sku to its friendly name an have PowerShell do a lookup.

The script will first lookup all users that are currently licensed so it does not attempt to look up a null value. It will then go through each licensed user, take all of their licenses and put it in an array, do a lookup on each license they have and export the user’s Display Name and friendly license name to a CSV file. It will append the results to the CSV so it does not overwrite the file.

Single Tenant:

The results will display the user and their friendly … Continue...

Create Bulk Office 365 Compliance Searches with PowerShell

March 18, 2018 Brad Wyatt Comments 0 Comment

Recently I wanted to find a way to get PowerShell to create compliance searches that followed keyword queries and search conditions. This means I could have multiple values in one search query. For example, “TO brad wyatt AND FROM [email protected]”. This query would search for e-mails sent to Brad which only from [email protected]. To get PowerShell to do this I decided to create a Hash Table that would have the queries listed in the table.

After it would create each compliance search it would then wait for the search to gather all of the results and then export the amount of items it found to a csv file. Each Compliance Search would append its results to the same file so in the end I would have a CSV file containing all of the Compliance Searches and the objects it found for each one.

To keep from having the Compliance Search … Continue...
