At the TEC 2023 conference in Atlanta, Greg Taylor (Microsoft) analyzed the four-year project he led to remove basic authentication from Exchange Online. Microsoft will reuse the methods and tools developed for this project when it removes other features from Microsoft 365.
A beta version of a Graph API to delete Teams chat threads allows administrators to remove unwanted chats. This article reviews how the API requests work to delete, list, and undo deleted chat threads using cmdlets from the Microsoft Graph PowerShell SDK. The first step is to find chats to remove, so we wrote a script to report all the chat threads for the signed-in user.
Many questions arose from the announcement of the Microsoft 365 multi-tenant organization (MTO) feature, In this article, I examine some practical aspects of multi-tenant organizations and examine why MTO does not replace the need for tenant-to-tenant migrations.
Microsoft has changed the way that the Search-UnifiedAuditLog cmdlet works without saying anything to Microsoft 365 customers. The results is that some scripts don't work and others won't return the expected results. This article explains what's happened and offers a workaround. Microsoft's actions are unexplainable, but it's the norm in this area where audit log changes happen without communication all the time.
A reader asked how to use a CSV file for bulk license assignment with the Microsoft Graph PowerShell SDK. We didn't have one to hand, so we wrote a new script to illustrate the principles of how to process license assignments for a set of user accounts (which don't necessarily have to come from a CSV file). We even included some error handling!
The multi-tenant organization (MTO) is a Microsoft 365 solution built on top of Entra ID cross-tenant synchronization. An MTO can span up to five tenants each with up to 100,000 synchronized users. It's an interesting solution that should be of interest to many large enterprises.
The Microsoft Graph PowerShell SDK uses a default enterprise app to hold its permissions. Over time, the SDK can accrue many permissions, so it's important to control interactive access to it. In this article, we review how to lock down the SDK app and how to create new registered apps for use with the Graph SDK.
Microsoft 365 Copilot is only available for 4 Microsoft 365 SKUs. There's no technical reason why this is so. Instead, Microsoft is using Copilot as a selling point to convince customers to upgrade to Microsoft 365 E5 (preferably). All's fair in love and business, and this is just an example of product management for maximized profit.
Microsoft 365 makes it easy for administrators to get mail activity usage data for users. However, if you want to know which domains are sending most mail, you need to do some work. In this article, we cover how to use cmdlets from the Microsoft Graph PowerShell SDK to create reports about user mail activity over time and the traffic sent by different domains.
From mid-August 2023, Exchange Online will enforce the action defined in the sender DMARC policy for inbound messages detected as spoof (by spoof intelligence). Tenants have the chance to amend their anti-phishing policy to decide what to do with these messages. I favor an outright rejection.
The TEC 2023 PowerShell Challenge Champion will be known after three rounds of frenetic script coding at The Experts Conference in Atlanta on September 19, 2023. Competitors will need a working knowledge of Microsoft 365 PowerShell, including Exchange Online, Teams, and Azure AD. Being able to think on your feet and come up with working solutions to problems is possibly a more important attribute than coding genius.
Microsoft 365 Copilot is priced at $30/user/month. At that price level, you don't want to assign Copilot licenses to all and sundry in your tenant. That's a recipe for dramatic overspending. In this article, we consider how to select people to receive Copilot licenses on the basis of real need rather than want.
