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.
Recuperação do Onedrive não funciona.
Não sei o que aconteceu, mas nos dias 04 e 08, dois dias que não acessei meu onedrive, milhares de arquivos meus foram deletados. Foram parar na lixeira, tentei de várias formas restaurá-los, mas o onedrive não permite restaurar todos de uma vez e depois de horas tentando, percebi que nunca iria conseguir terminar. Resolvi tentar a restauração do onedrive para o dia 04/09 as 00h00, mas a restauração nunca funciona, para pelo meio do caminho e a todo instante pede nova autenticação, tornando também inviável a recuperação dos arquivos. Não posso perdê-los e amanhã é o prazo de retenção dos arquivos e isso se tornará irreversível. Preciso de ajuda URGENTE para resolver esse problema, pois nada está funcionando e não encontro respostas para solucioná-lo. Tenho várias imagens de tela gravadas provando que depois de horas, nunca sai do 0% e também das constantes solicitações de verificação que impedem a restauração de forma funcional. Espero realmente que resolvam esse problema e restaurem meu onedrive por completo para o dia 04/09 as 00h00 ou precisarei tomar as medidas necessárias por terem eliminado definitivamente meus arquivos sem que eu tivesse a chance de recuperá-los. Agradeço a atenção e aguardo providências URGENTES!Save the Date: Join us October 20 for the OneDrive + Copilot Digital Event

A OneDrive sync failure can be deceptively simple. You edit a document, save it, and expect it to appear in the cloud. Instead, OneDrive displays “This file can’t be synced.” The file remains on your computer, but the cloud copy is missing or outdated link to the post
Did MS disable access to SharePoint through File Explorer today?
Just prior to 1:00 PM Eastern today, my entire company lost the ability to access our SharePoint server through File Explorer - in unison. Our IT dept. claims that MS has been threatening to disable the feature for a while. But I'm not finding any alerts, questions, or discussions about it anywhere online; and we can't be the only ones who would have noticed if this is a Windows-wide change.Mac OS 26.7 and M365 Office Applications- upload block errors only on Office applications.
Mac OS 26.7 and M365 Office Applications- upload block errors only on Office applications. When making changes to an Office document like Excel &/or Word using M365 E5 license since September 19th, I have been getting a message stating "Upload blocked" in autosave, the file is being saved to a OneDrive connected services which has a capacity of 5 tb, having a total of about 860,000 items, about 3.2 TB, but the selected items to sync from the OneDrive application is about 180,000. This happens sporadically to only Office application files such as MS Word and Excel. The syncs in the bar menu of OneDrive all show sync and backed up with no errors. As per MS a M365 SharePoint library can hold 30 million items, and view is limited to 5000 items, and I have such libraries with about 20,000 items and I can access them online and have set views to show items in lists less than 5000. MS also states that OneDrive Business can sync up to 300,000 items only even if the capacity is 5 TB and the number of total items cannot exceed 300,000 items. (1) Does anyone know why a OneDrive storage which leases 5tb storage space can only keep 300,000 items, for it to function? (It’s pointless to lease 5tb and be restricted by number of items). (2) Sync is working for PDFs and screenshots but only Office applications are having problems syncing at times or saving with autosave with versions. When I researched with CoPilot Premium running several terminal commands it concluded it is a MS Office bug and MS Support cannot solve the problem despite opening several tickets. The agents as L1 will scope, then it goes to the backend team called “ Escalations” but there remains no solution for crippled services since past 11 days. OneDrive sync logs were provided as well as requested but no followup. (3) If these are hard limitations on M365 to save maximum of only 300,000 items has anyone considered any other cloud services to replace OneDrive for Business? Has anyone else experienced this in the past? Can anyone offer a solution for this? If OneDrive office applications are dysfunctional then how does one operate AI agents or any automation. Any questions please ask. Thank you.
Working with ONE DRIVE
Good evening, everyone. I’d like to ask a few questions about OneDrive: If I have OneDrive active and am working on a Word document stored on my local drive, when I finish and click "Save," where is it saved—locally or on OneDrive? If I pause synchronization with OneDrive—or, better yet, uninstall the OneDrive app—what happens to the files currently in the OneDrive cloud? Will they be lost? I would appreciate your feedback. Regards. Luis Fernando.Can't drag title bar icon for OneDrive files
Something happened with Mac OS, or OneDrive, or my computer.... Can anyone confirm or replicate? I often have a doc open in word and I want to send to someone, so I save it and drag the title bar icon, maybe called the proxy icon, to an Outlook email or into Teams. There are other ways to do it, but i like that one. At some point in time that stopped working for OneDrive hosted files. Files not in OneDrive it works fine including files in DropBox. Can anyone confirm or deny it works that way for them? Rob.
MCP Integration for OneDrive/SharePoint
Hi OneDrive Team, I'm reaching out to explore Model Context Protocol (MCP) server integration for OneDrive and SharePoint. I am looking to integrate OneDrive/SharePoint data access into ThoughtSpot application using MCP solution. Are there existing MCP server implementations (official or community-driven) for OneDrive/SharePoint? If available, what are the connection endpoints and authentication details needed to set up the MCP server? If no MCP server currently exists, are there any upcoming plan on this and is there any alternate recommended approach present. Also could you please provide a SPOC from your team who can support further discussions and technical guidance on this integration? I'd like to schedule a follow-up conversation to explore the best path forward and discuss the use case. Thanks in advance for your help.
