How to Permanently Remove Mailbox Items with the Graph API

Permanent deletiion of mailbox items

Some new Graph APIs were announced on April 1 to close a feature gap with EWS. The new APIs permanently remove mailbox items and other objects, including folders, calendars, and calendar items. Permanent deletion means that items cannot be recovered through clients because they end up in the Purges folder in Recoverable Items. This article explains how the new APIs work, including a practical example.

Microsoft Attempts to Fix Microsoft Graph PowerShell SDK Problem with Azure Automation

Buggy Microsoft Graph PowerShell SDK

V2.26 and V2.26.1 of the Microsoft Graph PowerShell SDK were low-quality, buggy disasters. Microsoft aims to fix the problem in the next version to make it possible for the SDK to work with Azure Automation runbooks again and address many of the obvious problems that should never have appeared outside Microsoft. It will take time for customer confidence to be restored.

Reporting the Creation of SharePoint Agents

Sharepoint agents and audit records

Any site member can create a SharePoint agent. There’s no out-of-the-box method to report the creation of agents, but agents are created like any other file, and SharePoint Online captures audit records for file creations. Some PowerShell retrieves the file creation events and extracts the necessary information about who is creating agents and what sites the agents are created in.

Transferring Meeting Ownership From an Ex-Employee Can Be Hard Work

Transfer meeting ownership

Neither Outlook nor Teams includes a transfer meeting ownership feature for user calendars. Moving meetings owned by an ex-employee to give someone else the ownership requires manual intervention to find and reschedule meetings. Administrators can cancel future meetings for a user. In this article, we explore how to generate a report of meetings that might need to be rescheduled.

Artificial Intelligence, PowerShell, and Microsoft 365 Administration

artificial intelligence and powershell

Artificial Intelligence and PowerShell should be a good thing to help hard-pressed Microsoft 365 tenant administrators cope with common tasks. The early signs are there with Copilot in the Microsoft 365 admin center. However, the current state of the art depends on what’s gone before and can’t handle the kind of complex automation that tenants sometimes need, like generating a licensing report from Entra ID, product information, and license costs.

SharePoint Online PowerShell Module Gets Modern Authentication

SharePoint Online PowerShell Module Upgraded from IDCRL to OAuth

Microsoft has announced that the SharePoint Online PowerShell module will be upgraded from the very old and now obsolete IDCRL protocol to use modern (OAuth) authentication in versions released from March 28, 2025. The update to OAuth should not affect scripts, but it’s always wise to test in case your use of the module is an edge case that Microsoft doesn’t test.

Microsoft Graph PowerShell SDK V2.26.1 Remains Flawed

Microsoft Graph PowerShell SDK V2.26.1 remains flawed

The developers rushed out Version 2.26.1 of the Microsoft Graph PowerShell SDK to fix some obvious issues. Alas, problems persist in PowerShell SDK cmdlets, including licensing failures and an issue that prevents the Connect-MgGraph cmdlet from being able to obtain an access token from Entra ID. My advice is to stay with V2.25 until Microsoft resolves the problems and generates a new stable version of the SDK.

Processing Multiple Message Attachments with the Microsoft Graph PowerShell SDK

Add attachments to email with the Graph SDK

Many examples are available online to explain how to add a single attachment to messages using the Microsoft Graph PowerShell SDK. Here we look at the principles behind how to add attachments (one or many) to messages before sending them with the Send-MgUserMail cmdlet. Get the principles right and you’ll never go wrong!

Microsoft Graph PowerShell SDK Needs to Fix Its Password Problem

Graph SDK plain text passwords problem

The Microsoft Graph PowerShell SDK offers developers easy access to data across the Microsoft 365 ecosystem and that’s good. However, there’s a problem with Graph SDK plain text passwords that must be fixed. In today’s threat climate, passwords should be passed as secure strings. It’s a small but important step to improve overall security.

Primer: Using Exchange Online PowerShell in Azure Automation Runbooks

Using Azure Automation to process Exchange Online data

In this primer, we cover how to create and execute Azure Automation Exchange Online runbooks (scripts) using cmdlets from the Exchange Online management module. Some setup is necessary before runbooks can process Exchange cmdlets, but once the necessary resources and permissions are in place, it’s all plain sailing. The next challenge is how to output data created in a runbook…

Primer: How to Schedule Azure Automation Runbooks to Process Microsoft 365 Data

Use automation schedules to execute Azure automation runbooks

After creating a runbook to process Microsoft 365 data, registering the runbook with an automation schedule means that the runbook will execute on a reliable basis. This article discusses how to publish and register a runbook so that an automation schedule takes over the burden of running the job. In addition to describing the necessary steps in the Azure portal, we also give you the PowerShell commands.

Primer: Output Data Generated with an Azure Automation Runbook to a SharePoint List

The second part of the Azure Automation runbook primer brings us to output, specifically how to create items generated by a runbook in a SharePoint Online list. Once in the lists, items can be processed using Power Automate, Power Apps, or Power BI or exported to Excel. It’s a great way of capturing information generated by background jobs.

How to Replace Group Owners When They Leave the Organization

Replace group owners. (Microsoft 365 Groups)

Deleting an Entra ID user account can result in ownerless groups if the account being removed is the only group owner. Before deleting accounts, it’s a good idea to proactively replace group owners. This article explains how to replace group owners in the fastest and most scalable manner using the Microsoft Graph PowerShell SDK.

Final Days for the MSOnline and AzureAD PowerShell Modules

After many twists and turns since August 2021, the MSOnline module retirement will happen in April 2025. The AzureAD module will then retire in the 3rd quarter. It’s way past time to upgrade PowerShell scripts. The question is whether to use the Entra module or the Microsoft Graph PowerShell SDK. I know which option is best and say why in this article.

Using the SharePoint Pages Graph API

Microsoft released the SharePoint Pages API in mid-2024. This article describes how to create and publish a news item using cmdlets from the Microsoft Graph PowerShell SDK based on the API. The net result is that the API appears to work well but some problems are evident in the cmdlets. Or maybe it’s just my lack of knowledge!

All About the Office 365 for IT Pros GitHub Repository

The Office365ITPros GitHub repository holds over 300 PowerShell scripts showing how to interact with Microsoft 365 and Entra ID. Anyone can contribute to Office365ITPros by forking the code to a copy of the repository and making changes to scripts there. If you want, you can push the changes back to us so that we can consider their inclusion in Office365ITPros. It’s a great example of community in action.

Processing Microsoft 365 Retention Labels with the Microsoft Graph PowerShell SDK

Two types of retention labels are in use: Microsoft 365 retention labels and MRM retention tags. Clients hide the difference, but the Microsoft Graph PowerShell SDK cmdlets can only process Microsoft 365 retention labels for files stored in SharePoint Online and OneDrive for Business. EWS can manage MRM retention tags, but it’s on a fast path to retirement in 2026…

Using the Audit Log to Generate a Daily Action Summary for a User

This article describes how to report the audit events for a user over a single day. The task seems simple, but inconsistency in audit payloads makes it harder. Workloads don’t help by the variations in audit events. In any case, persistence and knowledge about what the audit event captured for an action helps to decode the data, as illustrated by the script detailed here.

Use the Audit Log to Find the Last Accessed Date for Documents

File Operations Audit Events

The unified audit log is full of interesting information about who did what and when they did it. In this article, I describe how to use file operations audit events to find the last accessed date for documents in a SharePoint Online site. It’s data that isn’t available in the Microsoft Graph, but it is in the unified audit log.

Manage PIM Role Assignments with the Microsoft Graph PowerShell SDK

This article describes how to create eligible and active PIM role assignment requests using cmdlets from the Microsoft Graph PowerShell SDK. Although the PowerShell code is straightforward, Microsoft recommends using the Entra admin center for Privileged Identity Management. But you can automate the management of role assignment requests if you want to.

How to Use the Graph SDK to Manage Group-Based Licensing

Group-based licensing is a mechanism to make it easier to assign and manage product licenses for large sets of user accounts. In this article, we discuss how to use Microsoft Graph PowerShell SDK cmdlets to manage group-based license assignments in a Microsoft 365 tenant. Assigning licenses to groups is very much like direct assignments, but some differences exist.

How I Write PowerShell Scripts for Microsoft 365

The question of how best to write PowerShell for Microsoft 365 was asked during a TEC 2024 PowerShell workshop. There are many variables, and one has the right answer. To start the ball rolling, this article describes how I write PowerShell for Microsoft 365 using a variety of modules such as Exchange, SharePoint, Teams, and the Microsoft Graph PowerShell SDK.

Microsoft Retires the Revoke-SPOUserSession Cmdlet

Unsurprisingly, Microsoft announced the deprecation of the Revoke-SPOUserSession cmdlet for November 2024. The cmdlet is replaced by the Revoke-MgUserSignInSession cmdlet, which works across Microsoft 365 rather than just SharePoint Online. All of this happened while the 2nd annual PowerShell Script-Off happened at TEC 2024 and competitors struggled with what to do to secure a user account for an ex-employee.

Installing the Entire Microsoft Graph PowerShell SDK Seems Like the Right Idea

An article described some benefits that could be gained from not installing the complete Microsoft Graph PowerShell SDK. The question is whether the claimed benefits are more theoretical than actual. It’s hard to say because it all depends on how someone uses the SDK for development or to run scripts. Anyway, it’s a topic worth discussing.

How to Add Contacts to User Mailboxes From a CSV File

Import contacts from a CSV File

A recent script demonstrated how to import contacts into user mailboxes using a list in a SharePoint site as the source. With a quick change, a CSV file becomes the source. This is a great example of how adaptable PowerShell is and how to update code found in articles to meet your needs. If you do ask an author to change their code, remember to try to make the change yourself first, and if you fail, explain to the author why the change should be made.

Transferring Reusable PowerShell Objects Between Microsoft 365 Tenants

People often need to transfer objects or code between Microsoft 365 tenants. When it comes to dealing with objects, the Microsoft Graph PowerShell SDK’s ToJsonString method is very useful. The method outputs a string containing JSON content, but only for object properties that have a value. This makes the much easier to use the output as the basis for a template object or as the payload body to create an object in another tenant.

PnP PowerShell Changes Its Entra ID App

On August 21, 2024, news emerged that the PnP PowerShell module will transition from using a multi-tenant Entra ID app to a tenant-specific app. The change is scheduled for September 9, 2024, which doesn’t leave a lot of time available for developers to review, update, and test PowerShell scripts based on PnP PowerShell. Some extra warning would have been nice.

Handling the Too Many Retries Error and Dealing with Odd Numbers of Audit Events

The AuditLog Query Graph API remains in beta status but cmdlets are now available in the Microsoft Graph PowerShell SDK. This led to some oddities in results when the number of audit events found by a search didn’t match those reported by the Purview compliance portal. It all worked out in the end. In other news, the Set-MgRequestContext helped sort out some retry problems.

The Maddening Side of the Microsoft Graph PowerShell SDK

All software has unique quirks, and the foibles of the Microsoft Graph PowerShell SDK are well known. But it’s much harder when the underlying foundation contributes to the craziness as described in this article. Graph pagination works in a specific way and Microsoft tunes the Graph to deliver great performance by reducing the set of properties returned for objects. Both can cause concern for developers.

Adding Cost Center Reporting to the Microsoft 365 Licensing Report

Microsoft 365 LIcensing Report

The Microsoft 365 licensing report now supports a cost center analysis based on cost center values stored in an Exchange custom attribute. The new analysis is entirely optional, but it seems like many tenants store cost center values in custom attributes, so this update might work well for them. That is, if the cost center data stored in Exchange is accurate… Rubbish in always means rubbish out…

Upgrading the Teams and Groups Activity Report to 6.0

The Teams and Groups activity report is a popular script that helps administrators identify inactive teams and groups within a Microsoft 365 tenant. The script code has been developed over the years. The last version converted to Graph API requests to improve performance. This time, the upgrade is to use the Microsoft Graph PowerShell SDK to make the code easier to maintain.

The Right Way to Replace the Remove-SPOExternalUser Cmdlet

Microsoft says they will remove the Remove-SPOExternalUser cmdlet starting July 29. They recommend using Remove-AzureADUser as a replacement. It’s a bad call because that cmdlet is part of a now-retired and soon to be deprecated module. Overall, recommendations like this make you think that Microsoft doesn’t know what’s happening across the whole of Microsoft 365. And you might be right.

Adding Details of Authentication Methods to the Tenant Passwords and MFA Report

V1.2 of the User Passwords and MFA report includes the names of authentication methods registered for user accounts. V1.3 expands the amount of detail reported for each method, such as the phone number used for SMS challenges, or the email address used for SSPR. It’s a small but important detail that’s useful to administrators. However, it also comes with a potential privacy issue, so the script must handle that too.

Planner User Policy Stops Task and Plan Deletions

The Set-PlannerUserPolicy cmdlet allows Microsoft 365 tenant administrators stop users deleting tasks created by other users. However, an undocumented consequence of setting the policy for user accounts is that it stops those accounts removing plans too. The unexpected block imposed by Set-PlannerUserPolicy caused me problems when attempting to delete a plan with PowerShell. It would be nice if the modules created by Microsoft worked as expected (and as documented).

Version 1.9 of the Microsoft 365 Licensing Report

The Microsoft 365 Licensing Report is a popular PowerShell script that’s just been updated to V1.9 with a bunch of changes to highlight different aspects such as license costs for disabled user accounts and inactive user accounts. Copious use of some very dubious color choices makes the HTML report created by the script look very nice (if you’re color blind) and the new version can generate an Excel worksheet.

Working with Calendar Permissions using the Microsoft Graph PowerShell SDK

The Set-MailboxFolderPermission cmdlet is usually used to set calendar permissions, including the permission for the default user to allow everyone in an organization to see each other’s calendars. But you can use cmdlets from the Microsoft Graph PowerShell SDK too. The Graph SDK cmdlets are faster, but not enough to warrant replacing the Exchange cmdlet in scripts. We explain why here.
