AutoSave disabled when opening SharePoint-synced files from Finder after macOS Tahoe 26.6 update
Files stored in SharePoint Online and synchronized locally through OneDrive are opened as local documents when launched from Finder. Office applications display "Saved to my Mac" and AutoSave is turned off by default. However, opening the exact same files through Word/Excel > Open > Sites, or via SharePoint "Open in Desktop App", correctly identifies them as cloud documents. In that scenario, AutoSave is enabled and collaboration/version history features work as expected. Troubleshooting already performed: OneDrive reset and re-linked SharePoint library re-synced Signed out and back into both Office and OneDrive Removed Microsoft credentials from macOS Keychain and re-authenticated Recreated local OneDrive sync relationships Verified OneDrive File Provider extensions are enabled Verified Office applications and OneDrive are fully up to date Tested with newly created files and existing files Tested "Always Keep on This Device" with no change in behavior The issue appears to be specific to the Finder-to-Office launch path after upgrading to macOS Tahoe 26.6. Before upgrading to macOS Tahoe 26.6, opening the same SharePoint-synchronized files directly from Finder correctly preserved cloud document identity and AutoSave was enabled as expected. I discussed this issue in detail with Apple Support, but they quickly dismissed it, saying that the problem is not on Apple's side and that I should contact Microsoft instead.
Locked out of Microsoft 365 Business Tenant
I am the sole global admin for my Microsoft 365 Business tenant and I have been completely locked out due to an MFA issue. I cannot access the admin portal, cannot reset MFA, and cannot verify my identity through the automated system. When I call Microsoft support, the automated system incorrectly states that I am not a global admin and immediately disconnects. All UK support numbers (0800 026 0329, 0344 800 6006, etc.) hang up instantly before reaching an agent. No callbacks have been received despite multiple requests. I now have an open case with the Data Protection team: Microsoft 365 Data Protection – TrackingID#2609030040002192 This situation has caused: Business disruption Financial loss Inability to manage users or services Customer service impact Complete loss of administrative control over our tenant I urgently need escalation to the Data Protection team for identity verification and MFA reset. The normal support channels are not functioning, and I cannot reach a human through any published phone number. Any assistance or escalation from Microsoft moderators or engineers would be greatly appreciated. Thank you.
Turning off email notifications about new comments in one certain file
Hi All! I found a solution to turn off all email notifications on new comments in my shared files (through settings on SharePoint), but it doesn't really solve my problem. In project files I work on with my colleagues, email notifications are helpful for monitoring workflows and streamline the process. At the same time, I'm an owner of yearly excel files shared with a big team in order to monitor the work on all clients and automate the visualization of it, but it gets commented on a lot and I don't need to get all of that on my Outlook. Is there any way to turn off email notifications about new comments for just one file without turning them off on all my shared files? Kind regards, Jakub BanasikBC SharePoint External File Storage view threshold exceeded
I recently set up External File Storage in Business Central. The view and folder structure were automatic, and the file links and communication between the two applications seems tenuous. Very quickly I ended up with a view threshold exceeded error in the SharePoint library. I was told that this is a known issue and Microsoft suggested the below mitigations. I plan to do the indexing when I don't have users logged in. I simplified the default view. I can't apply a retention policy in BC because the associated table is not included in the allowed tables. I'll give some thought to the Azure Blob storage option. My question, however, is what do they mean by "Partition attachments across multiple libraries"? This option intrigues me but how do I do that without breaking the file link between BC and SP? TIA. Recommended Mitigations Action Purpose Index key columns on the BC-managed library Enables filtered views past 5,000 Simplify default view (remove sorting/grouping/lookup columns) Avoids unnecessary joins that trigger LVT Partition attachments across multiple libraries (per company/environment/year) Keeps each library under threshold Apply BC attachment retention/archival Controls long-term volume Consider Azure Blob/Files for high-volume scenarios No equivalent list-view constraint
How much of your Microsoft 365 environment can you actually see at once?
Not how many users you have. Not how many sites, teams, apps or flows you have. How much of it can you actually see connected together? I've been working across Microsoft 365 environments for a while, and I kept running into the same thing. There is no shortage of information. If anything, there is probably too much of it. Users, groups, permissions, SharePoint, Teams, Power Apps, Power Automate, Power BI, Dataverse, OneDrive, Exchange, Intune, licensing, configuration... It's all there. But when you're actually trying to understand how everything fits together, it can be a different story. You open one blade. Find something. Open another. Cross-check it. Go back. Open something else. Before long, you're jumping between different parts of the tenant trying to build the bigger picture in your head. And if you're working with larger environments, that gets difficult pretty quickly. The information isn't necessarily missing. The relationships between the information are what can be difficult to see. That got me thinking about a slightly different question: Instead of "where do I find this information?" "Show me what's connected to this." That's where VisibleState started. Start anywhere. Follow the connections. Imagine starting with a single user. Instead of seeing that user simply as a record with a list of properties, imagine being able to explore the relationships around them: User → Groups → SharePoint → Teams → Power Apps → Power Automate → Power BI → Dataverse → OneDrive → Exchange → Intune Then the questions become different: What does this user have access to? Is that access direct or coming through a group? What resources are connected to them? What depends on something they're associated with? Which licenses are involved? Are there relationships that look unusual? If something changes, what else might be affected? Those questions aren't necessarily about finding another piece of information. They're about putting information that already exists into context. A report can tell you that something exists. A connected view helps you understand what it is connected to. Illustrative example below — not a real customer environment. I'm not suggesting Microsoft 365 doesn't already give us this information Quite the opposite. Microsoft 365 already gives administrators an incredible amount of information and tooling. The thing I've been thinking about is what happens when you want to look across those boundaries. Sometimes I don't want another export. I don't want another list. I don't necessarily want another dashboard. I want to start with something I'm looking at and ask: "What's connected to this?" And then keep following the trail. That's the idea I'm exploring with VisibleState. The interesting part is what happens when you change the viewpoint The same relationships can be useful for completely different reasons. For example: Administrators may want to understand access, permissions and dependencies. Security and governance teams may want to find unusual relationships or exceptions. Compliance teams may need to understand who can access something and why. People managing multiple environments may want a consistent way to understand what's there without rebuilding the picture manually every time. Leadership may not need to see the graph at all. They may simply want to know what's important, what's exposed and what could be affected. It's still the same underlying environment. You're just looking at it from a different angle. And that's where I think things get interesting. Where I'm at with it VisibleState started as something I was building to make my own work easier. I was spending a lot of time investigating environments, tracing access and putting information together for reports. The individual tasks weren't necessarily difficult. It was the jumping between different places and reconstructing the bigger picture that took the time. So I started building something that would let me approach the environment through the relationships instead. It's grown quite a bit from where it started, and I'm continuing to build it. I'm not posting this as a product launch, and I'm not looking for people to sign up. I'm genuinely interested in whether the problem I'm seeing is familiar to other people working with Microsoft 365. So I'm curious... If you could start with any object in your Microsoft 365 environment and immediately see what it's connected to, where would you start? Would it be: Users and access Groups and permissions SharePoint and Teams Power Apps, Power Automate, Power BI and Dataverse Licensing and resources Governance and unusual relationships Something completely different Maybe you've already got a good way of doing this. Maybe you still find yourself jumping between different services and piecing things together manually. Or maybe I'm looking at the problem from the wrong direction. What's the one relationship in your Microsoft 365 environment that you wish you could see instantly?Backout Plan for EWS to MS Graph API upgrade for SharePoint|sapiens
Microsoft has announced the retirement of Exchange Web Services (EWS) in Exchange Online, effective October 1, 2026. After this date, EWS-based integrations will no longer be supported. To ensure uninterrupted email functionality, all affected SharePoint|sapiens solutions must be upgraded to use the Microsoft Graph API. My question is this - if we upgrade to Graph and our SharePoint|sapiens solution goes sideways somehow, is backout / rollback to EWS an option? I realize we could only roll back until 10/1 since that's the EWS retirement date, but our leadership may request that we make our solution functional temporarily (if the upgrade causes a problem) by rolling back.The Case of the Massive Loop Container
Why would a seemingly simple Loop workspace develop into a monster SharePoint Embedded container? That’s the question to answer when a Loop container grew to fill nearly 88 GB of SharePoint Embedded storage. The workspace had been through many hundreds of edits, but that’s an unlikely reason to spread and occupy so much storage. Loop and SharePoint Embedded are black boxes when it comes to administration, so we must wait for Microsoft to explain. https://office365itpros.com/2026/08/27/loop-workspace-big-container/What Are Some Best Practices for Securing SharePoint?
SharePoint has become an important part of how modern organizations store documents, share information, collaborate on projects, and manage business processes. But as more sensitive information moves into SharePoint, security needs to become a priority rather than an afterthought.

SharePoint makes it easy for teams to store, share, and work on files from almost anywhere. But when you click on a document and it refuses to open, that convenience can quickly turn into frustration. You may see a blank page, an error message, an endless loading screen, or nothing at all. Sometimes the problem affects only one file, while in other cases, an entire SharePoint library seems to stop working. Link to the post
How can I test block download policies in SPO?
I have a Microsoft 365 E5 developer tenant. However, I am unable to activate the SharePoint Advanced Management trial from the SharePoint Admin Center. I need to verify my code in this configuration. Specifically - I need to check how `File.OpenBinaryStream()` behaves. Please advise.
