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.Making Mac OneDrive Faster and More Reliable
OneDrive on macOS is getting a major update to how it syncs! The Native Sync Engine is rolling out to Insiders today with version 26.098. It's up to 2x faster on initial sync and on-disk state changes, uses less CPU, memory, and battery, and removes the hidden cache folder that's been the source of most reliability issues since 2022. It's the latest in an ongoing effort to make OneDrive feel native on Mac. Earlier this year we shipped a redesigned Activity Center with Liquid Glass and native dialogs, and the Native Sync Engine is a major step in that journey. The cache folder problem When we moved OneDrive to Apple's File Provider platform in 2022, we needed a way to bridge the existing sync engine with how File Provider expected things to work. Broadly, there are two parts to OneDrive sync: the sync engine itself, and the code that OneDrive uses to work with files. To support File Provider, we had to change how OneDrive interacted with the file system. However, to reduce risk, we decided to use a hidden cache folder that mirrored your OneDrive contents, so the sync engine could remain largely unchanged. That cache folder solved the immediate problem and unlocked features like Known Folder Move. Over time, however, feedback and telemetry showed us that it was root cause of many of the reliability and performance issues users have reported since. The Native Sync Engine removes it. What’s changed Over the past several years, we’ve been working behind the scenes on the Native Sync Engine. Building it required us to completely rebuild large portions of our code and build a new sync platform that allows OneDrive to work better with the File Provider system. The Native Sync Engine provides the fastest, most reliable experience we’ve ever delivered on the Mac. It has a simplified architecture, eliminates entire classes of errors, and integrates more deeply with macOS. In our performance testing, the new system is about 2x faster for initial sync and on-disk state changes. It also uses fewer system resources, helping preserve your Mac’s battery life while improving overall responsiveness. We’ve also put the new system through multiple tests that simulate usage well beyond what the average user would ever do, and it has held up extremely well in those scenarios. It’s a massive improvement, and one we are very excited to bring to you. On the surface, the Native Sync Engine looks and feels very similar to what we had before, but there are a few important changes. Let’s walk through a few of them. Hidden folders no longer hold data OneDrive's hidden folders now contain metadata only. Your file data only lives in the OneDrive folder you interact with directly. There are a few cases where a copy of file data will exist in the hidden folder: Files you've created or changed that haven't uploaded yet. The copy is removed once the file has fully synced to the cloud. OneNote shortcuts and similar "link" file types. These are typically a few hundred bytes at most, and we retain them in the hidden folder indefinitely. Some kinds of macOS packages, such as GarageBand files, .app bundles, and certain older iWork files. Copies of these files are retained for longer than most files. Files and folders are always browsable Files in a folder used to be created on disk only the first time the folder was accessed. That led to Finder showing "Loading..." while you browsed and apps hanging while they waited for folders to materialize. Now, every folder and file is always browsable on disk. Navigating your OneDrive folder feels like navigating any other folder. It’s snappy, responsive, and just works. Note that Files On-Demand is unchanged with the Native Sync Engine. Files you haven't opened remain online-only unless you either open them or mark them Always On This Device. External drive support The Native Sync Engine also supports external drives, such as USB drives you can plug into your Mac. If your system and your external drive meet the requirements, all of your files and OneDrive's metadata folder will be placed on this drive. On older versions of macOS and on drives that don't meet the requirements, your files and OneDrive metadata will be stored on the home volume. Syncing shared folders and libraries If your organization has disabled the “Sync” button on SharePoint and your users are using “Add shortcut to My Files”, you can skip this section, as you are already in the ideal state! If you are still using synced libraries, each synced library now appears as its own root in the Finder sidebar, instead of nested under a single tenant entry. Add shortcut to OneDrive remains the modern way to access shared content. Admins can hide the Sync button via aka.ms/HideSyncButton. Identifying the Native Sync Engine You can identify whether your Mac is using the Native Sync Engine by inspecting the OneDrive version in the Preferences dialog: If the version ends with a value such as "(26K)", you are running the Native Sync Engine. If the version ends with the version of macOS, you are not yet running the Native Sync Engine. Rollout Starting today, we’ll be gradually rolling out this new experience to our Insiders audience. This rollout will take several weeks to complete. If you aren't already in Insiders and want to try the new update, simply open OneDrive preferences, click on the About tab, and check the box to join the Insiders program. Your Mac will upgrade to the Native Sync Engine automatically when it receives the update. It might take a couple of minutes for OneDrive to complete the upgrade, and a little while longer for File Provider to finish with the upgrade, but you can still use your OneDrive while this is taking place.

Today, we’re introducing native Markdown support in SharePoint and OneDrive, now rolling out to general availability across both consumer and commercial audiences. As AI and agents increasingly create and update Markdown files to carry out work, teams need a reliable place to manage that content. SharePoint and OneDrive make it easy to view and edit these files in the browser when precision, intent, or changes are required, with built‑in versioning and governance. Markdown files are now fully integrated into the Microsoft 365 file experience, behaving like any other file in your workflow.
A few questions to the new Outlook365 on Windows
Hey. After many years, i switched from Office2021 to Office365, mostly because of the 1TB OneDrive storage and more up2date software. I installed the so called "new Outlook365" desktop on my Windows computer. The program says: Microsoft Outlook-Version 1.2024.807.100 (Production). I am not sure if its already a final product or a beta version 😕 I use outlook for many of my e-mails and to manage my calendar/tasks/to do lists. My questions: 1) I added in the new Outlook365 several IMAP e-mail accounts and found nowhere a possibility to change the senders name, which is shown normally next to the e-mail adress. I changed the name in the webmail client from my webhosting account, but that didnt help either. --> Is it not possible in the acutally version for IMAP e-mail accounts to change the senders name? 2) How can i customize the left app bar in the new Outlook365? I see there only a few app icons, but no option to change them or to add for example OneDrive, To Do, etc. 3) How i can integrate my To Do List & One Note from Microsoft365 in Outlook? I have looked everywhere, but have found no option, how i can integrate them in the new outlook. Hope the community can help to resolve my problems. Thanks in advance.

OneDrive Access Issue – User Unable to Access OneDrive Despite Multiple Troubleshooting Attempts
Hello Community, We are facing an issue with a user who is unable to access their OneDrive. Whenever the user tries to access OneDrive, the same error message continues to appear (screenshot/error attached). We have already performed the following troubleshooting steps: Removed and re-assigned the Microsoft 365 license. Executed the required PowerShell commands and confirmed that the user has a valid OneDrive URL and access permissions. Verified OneDrive and SharePoint settings from the SharePoint Admin Center. Used Microsoft Support and Recovery Assistant (SaRA) and reviewed the recommendations provided. Attempted to re-provision the user's OneDrive site. Despite completing all the above steps, the issue persists and the same error continues to be displayed. Additional Information: User has a valid Microsoft 365 license assigned. OneDrive service is enabled for the user. SharePoint Online is functioning normally for other users. Re-provisioning OneDrive did not resolve the issue. Has anyone encountered a similar issue or can suggest additional troubleshooting steps to identify the root cause? Any guidance would be greatly appreciated.

Please helpHave OneDrive or SharePoint files/folders on home screen of iPad without internet connection?
This. I'm on a big iOS project. We have several users who need files on an ipad when traveling, and be able to open them when there is no internet connectivity. These files aren't intended to be edited, just 'read only.' These files do not contain any sensitive corporate data. The content lives in SharePoint online and I'm using OneDrive as a bridge to their sharepoint site. BUT the files can only be viewed on the ipad within the OneDrive app without internet access. These are devices using user affinity enrollment. Initially, the solution for users was to use the 'Mark Offline' feature within the OneDrive iOS app. I used Power Automate to have it fetch new files found in OneDrive and move them to the teams SharePoint site. These shared devices are locked down (an understatement). These will be used by the least computer savy/literate people and so having them dive through OneDrive folder after folder, even offline, is a tall order to ask. I totally get it and don't want them doing that either. So now I have to move onto plan B. How can we put the files that live within OneDrive/Sharepoint onto the home screen without an internet connection when the ipad is 'out in the field.?' This would make it infinitely easier for them. The key here is to not have end users manually moving files around. We don't want them to even have to go into OneDrive and mark folders/files offline, if possible. We don't have the SharePoint app on them. I tried the SP app a while back, and it is a hot mess of garbage. I could revisit it. Whatever I can get to work of course we'll have to modify our Intune polices. Thoughts?SharePoint Online Site Deletion blocked by Retention Policy although no content is retained
Hi everyone, I'm trying to understand whether this behavior is expected or if other organizations are experiencing the same issue. Environment SharePoint Online (Microsoft 365) Microsoft Purview Retention Policy Retention duration: 180 days Trigger: based on last modified date After retention period: Do nothing The intention of the policy is not to automatically delete content. We only want to prevent deletion for 180 days and allow deletion afterwards. Microsoft previously explained to us that retention applies to the content/items, not to the container (the SharePoint site itself). Problem We are currently unable to delete SharePoint sites. When attempting to delete a site from the SharePoint Admin Center we receive the following message: This site can't be deleted at this time because it is blocked by a compliance policy. What we already checked For the affected site: CompliancePolicyIds = empty ArchiveStatus = NotArchived SensitivityLabel = empty The Preservation Hold Library is empty: Preservation Hold Library => Items = 0 We also inspected the internal DLC properties of the site and found entries such as: dlc_sitehaspolicy dlc_sitehasexpirationpolicy dlc_webhasexpirationpolicy Even after clearing these values for testing purposes, the site still could not be deleted. Important Observation If we explicitly exclude the site from the retention policy, deletion becomes possible. This makes it appear that the retention policy is blocking deletion of the site container itself, even though our understanding was that retention should only protect retained content and not permanently prevent deletion of the entire SharePoint site. Has anyone else observed this behavior? Additional OneDrive Issue We are seeing a similar problem with unlicensed OneDrive accounts. Many of these OneDrive sites: are already archived are shown as blocked by retention/compliance cannot be deleted remain present for years For example: ArchiveStatus = FullyArchived CompliancePolicyIds = empty The accounts appear in the list of unlicensed OneDrive accounts, but we are unable to permanently remove them while the retention policy is in effect. Has anyone found a practical way to clean up or remove these orphaned/unlicensed OneDrive sites when a tenant-wide retention policy is configured? Questions Has anyone seen a situation where: CompliancePolicyIds is empty the Preservation Hold Library is empty but site deletion is still blocked by a compliance policy? Does a retention policy configured as: Retain for 180 days Then Do nothing intentionally block deletion of the entire SharePoint site container? Is it expected that excluding a site from the retention policy immediately makes deletion possible? How are other organizations handling site lifecycle management when tenant-wide retention policies are enabled? Has anyone experienced similar issues with unlicensed OneDrive accounts that cannot be deleted because of retention/compliance requirements? Any experiences, recommendations, or explanations would be greatly appreciated. Thanks!
