Can I restore my whiteboard created by Microsoft Whiteboard UWP?
I created several whiteboards by MS Whiteboard UWP in 2023. As I cannot transfer the data to new Whiteboard, I kept the old version ( Microsoft.Whiteboard_52.10201.5809.0). But days ago MS Store updated it automatically, and I lost my data. I didn't transfer it to OneDrive, so it should be stored on Azure. When I find the update (when it updated the local data should be already removed from my device) and recover the old version and login again today, I find nothing but a new created empty whiteboard, all of my data lost and I cannot access it from the cloud. How can I recover my data?

Microsoft would very much like Microsoft 365 tenants to use Copilot instead of ChatGPT. A recent comparison between Copilot and ChatGPT outlines some areas that Microsoft thinks are important when deciding which AI tool to use. Microsoft has a point because Copilot is embedded into Microsoft 365 whereas ChatGPT is more of an add-on. The competition for hearts and minds is very intense in the AI space. https://office365itpros.com/2026/02/20/copilot-and-chatgpt/Access to subAddress Property of Hyperlinks in Powerpoint Javascript API
Recently my company has me developing a Taskpane Add-in for Powerpoint using the Javascript API. Right now the API is still missing a 'subAddress' property for the Powerpoint.Hyperlink class. My heart's deepest longing is to add a slide to a presentation with existing slide-to-slide hyperlinks, check those hyperlinks for discrepancies between the slide ID and the text (ie: a Hyperlink reading '13' that now links to slide 14), and finally correct the text to the subaddress ID of the hyperlink in Javascript. It is my burning passion to do this for every hyperlink in my presentation with the push of a button. In the interest of all mankind I would ask that the 'subAddress' property of the hyperlinks be available for use in addition to the 'address' and 'screenTip' properties which now exist. To the microsoft dev who can grant me this boon I offer half my kingdom. Truly there is no dev more favoured than thee.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/
Cancelling Microsoft Customer Agreement (MCA)
I'm a Microsoft CSP provider. My customer wants to cancel their subscriptions because they want to leave the Microsoft. Do I need to cancel their MCA or will it be cancelled automatically?

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/
Bookings Page not sending confirmation emails to customers
Hello, I am the main technician for my company's service desk. We have a Bookings page, but any time anyone books a time slot, they receive a message indicating that they will receive a confirmation email, but no email comes to them. In the settings, it shows the checkbox to send a confirmation email is checked. I have also looked in Exchange Admin and run a message trace and cannot find any confirmation email sent to myself or other testers. In Bookings, I have unchecked the confirmation email checkbox, saved, checked, saved, and tested - same result. Additionally, this Bookings page is only for internal users, and all of them are 'customers' with their full organization email address. In researching, I found that there was mention of the Bookings needing to have an Exchange account as a shared mailbox, which I do not believe we have - when I search the email that confirms for me that someone has booked with me, it is a long string of seemingly random letters and numbers with an internal domain address. I have also tried searching in Exchange Admin for 'IT' 'Service Desk' 'Service', and 'Desk', none of which have any results under Mailboxes (which would include shared mailboxes). Any advice/suggestions would be greatly appreciated. Screenshot: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/
