Using Dev Proxy with the Microsoft Graph PowerShell SDK
Dev Proxy is a Microsoft tool built to help developers figure out the most effective way of using Microsoft Graph API requests. On the surface, Dev Proxy doesn’t seem like a tool that would interest people who use the Microsoft Graph PowerShell SDK to write scripts for Microsoft 365. But all tools have some use, and Dev Proxy can help. https://office365itpros.com/2026/02/19/dev-proxy-graph-sdk/PowerShell Basics: Don't Fear Hitting Enter with -WhatIf
Chances are you've run into this situation. You've built a script, or a one-liner, to perform a specific task, but you don't have a way to thoroughly test it without hitting Enter. That moment before hitting enter can be difficult. Knowing this need, there is a switch available with many PowerShell commands called -WhatIf .How to Use Scoped Graph Permissions to Access SharePoint Files
Scoped permissions grant apps granular access to files and folders in SharePoint Online and OneDrive for Business sites using the Files.SelectedOperations.Selected Graph permission. The permission allows apps to access specific files or all the files in a folder. It’s a great way to make sure that apps don’t have unfettered access to confidential documents. Not that any app would try to have that kind of access… https://office365itpros.com/2026/02/18/scoped-access-files-and-folders/Primer: How to Use RBAC for Applications to Control App Use of the Mail.Send Permission
The temptation to use the Mail.Send application permission in scripts can lead PowerShell developers into trouble because the permission allows access to all mailboxes, including sensitive executive and financial mailboxes. Fortunately, RBAC for Applications allows tenants to control the access that apps have to mailboxes and other Exchange content. All explained here with an example script to test RBAC of Applications. https://office365itpros.com/2026/02/17/mail-send-rbac-for-applications/Exchange Online PowerShell Dumps the Credential Parameter
On February 12, Microsoft announced the deprecation of the Credential parameter for the Connect-ExchangeOnline cmdlet in the Exchange Online PowerShell module. The deprecation won’t affect interactive sessions (which should all be protected by MFA), but it might stop some background jobs running when Microsoft retires the server components that currently support the ROPC authentication flow. Time to check scripts! https://office365itpros.com/2026/02/16/exchange-online-powershell-ropc/How to Deactivate an Entra ID Application
This article explores how to deactivate applications (aka disable apps) in Entra ID. Everything is done through PowerShell and the Microsoft Graph PowerShell SDK because the feature isn’t currently available in the Entra admin center. We’ve even included a fully functional example script to show you how the process works. Feel free to fix or enhance our code in GitHub! https://office365itpros.com/2026/02/11/deactivate-application-entra/
Document libraries added programmatically as tabs to Shared Channels are not visible
With the recent Teams UX updates, any document libraries added programmatically to Shared Channels no longer appear in the Teams interface even though they do show up when queried through PowerShell. Following the guidance in https://learn.microsoft.com/en-us/graph/teams-configuring-builtin-tabs%22https://learn.microsoft.com/en-us/graph/teams-configuring-builtin-tabs%22https://learn.microsoft.com/en-us/graph/teams-configuring-builtin-tabs%22https://learn.microsoft.com/en-us/graph/teams-configuring-builtin-tabs%22as well as the approaches I outlined in my blog post https://reshmeeauckloo.com/posts/powershell-teams-add-documentlibrary-as-tab/%22https://reshmeeauckloo.com/posts/powershell-teams-add-documentlibrary-as-tab/%22 using Microsoft Graph or PnP PowerShell, the tabs still fail to surface in the new Teams experience. The behaviour is inconsistent: The same tab‑creation methods work perfectly in standard channels. They also work for users who haven’t yet received the new Teams UX. And if the document libraries are added manually, they appear as expected in shared channels. At the moment, I’m trying to determine whether there is a supported way to add document library tabs to shared channels programmatically so that they remain visible in the new Teams interface. Any insights or confirmed workarounds would be appreciated.How to Report Adaptive Scope Membership
The Get-AdaptiveScopeMembers cmdlet reveals details of adaptive scope membership to make it possible to report this information programmatically. The task is not as simple as you might imagine. Summary records must be separated from member records, which can reflect add or remove operations. And there’s the question of pagination for large adaptive scope. All explained here with a PowerShell script to help. https://office365itpros.com/2026/02/09/adaptive-scope-membership/
File Type Version Limits
Hi all, In trying to solve an old issue I stumbled across this new feature currently in preview and am wondering if the file type arrays will be editable or if new arrays could be or will be added? I have a handful of file types which do not need 100 versions, let alone a version every 2-5 minutes, requiring frequent culling...
