AutoUpdate fails trying to update old V3.11 of AutoUpdate on MacOS Sequoia 15.8.1
I have the latest version of AutoUpdate (4.85) installed on my Mac. For several years and versions of MacOS, every time AutoUpdate runs it fails to update AutoUpdate Version 3.11 with a "Check Error..." or Download error. I've searched for solutions but only find how to totally disable AutoUpdate. I want to remove whatever remnants of V3.11 are somewhere on my system so I can run the latest AutoUpdate without this failure. Any suggested fixes...? TIAAutoSave 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.
OneDrive files opened from Finder not recognized as cloud files on Mac
Office for Mac: OneDrive files opened from Finder no longer recognized as cloud files – AutoSave disabled Hi everyone, I am experiencing a persistent issue with Microsoft 365 for Mac and OneDrive that started suddenly around August 10, 2026. The same setup and workflow had worked without problems for more than two years before that. Problem My Office files are stored in OneDrive and synchronized to my Mac via the standard macOS File Provider. When I open an Excel or Word file by double-clicking it in Finder, the Office application opens the file, but it apparently does not recognize it correctly as a OneDrive/cloud file. For example: AutoSave is disabled real-time co-authoring does not work as expected when I try to enable AutoSave manually, Office behaves as if the file were local and asks me to upload/save it to OneDrive – even though the file is already stored and synchronized in OneDrive However, if I open the exact same file from within Excel or Word via the OneDrive/Online Locations option, everything works correctly: AutoSave is enabled immediately co-authoring works changes made by another user appear in real time This behavior is reproducible with multiple files and affects both Excel and Word, so it does not appear to be an issue with one particular workbook or application. Environment MacBook Air M2 current macOS version current Microsoft 365 version current OneDrive version OneDrive Personal files synchronized through the standard macOS File Provider I have also tested opening files directly from: ~/Library/CloudStorage/OneDrive/... The result is the same: when opened from Finder, Office does not appear to recognize the file correctly as a cloud file and AutoSave remains disabled. Troubleshooting already performed I have already: completely reset and reconfigured OneDrive allowed OneDrive to fully resynchronize verified the files and folders in OneDrive on the web confirmed that OneDrive reports everything as synchronized restarted Finder and macOS removed and recreated Finder shortcuts/favorites tested without Finder favorites or aliases tested directly from ~/Library/CloudStorage/OneDrive updated macOS updated all Microsoft 365 applications updated OneDrive None of these steps changed the behavior. Key diagnostic result The following comparison is consistently reproducible: Finder → OneDrive file → double-click → Excel/Word → AutoSave OFF → file appears not to be recognized as an active OneDrive cloud document → co-authoring does not work correctly Excel/Word → Open → OneDrive/Online Locations → same file → AutoSave ON immediately → cloud functionality works → co-authoring works correctly This suggests that OneDrive synchronization itself is functioning correctly. The issue seems specifically related to the handoff between macOS Finder / Apple File Provider / OneDrive and Microsoft 365 for Mac when a OneDrive file is opened from Finder. Important detail This is not a workflow that has never worked on macOS. For more than two years, we routinely opened our synchronized OneDrive Word and Excel files directly from Finder. Office recognized them as cloud files, AutoSave was available, and collaborative editing worked normally. The behavior changed suddenly around August 10, 2026, without us intentionally changing the OneDrive folder structure or our workflow. Question Has anyone else encountered this recently? In particular: Is this a known regression in Microsoft 365 for Mac, OneDrive for Mac, or their integration with Apple's File Provider? Why would Office recognize a file as a OneDrive cloud document when opened through the application's Online Locations, but not when the exact same synchronized file is opened from Finder? Is there a way to reset or repair the Microsoft 365/OneDrive cloud-file recognition or File Provider integration without resetting the entire OneDrive again? Are there any relevant logs, caches or diagnostics that could show why Office considers a Finder-opened OneDrive file to be local? Opening every document through the Office application's Online Locations is a possible workaround, but it is not a practical long-term solution when working with a larger shared folder structure in Finder. I have already contacted both Apple Support and Microsoft Support. Apple referred me to Microsoft, and Microsoft Support subsequently recommended that I raise the issue here in the Tech Community. Any insight from Microsoft staff, MVPs or others familiar with Microsoft 365 for Mac, OneDrive and the macOS File Provider would be greatly appreciated.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.Office Home & Business 2019 license no longer recognized after reinstall ("No license found")
Hello everyone, I'm looking for some help because Microsoft Support has not been able to solve this issue. I own a genuine perpetual license of Office Home & Business 2019 for Mac, linked to my Microsoft account since August 2019. The license is still listed under Services & Subscriptions, but Office no longer activates. My hardware MacBook Pro (Retina, 13-inch, Late 2012) Model: MacBookPro10,2 Intel Core i5 8 GB RAM macOS Ventura 13.7.8 Installed using OpenCore Legacy Patcher Office version originally working: 16.78 Later tested with 16.101 and 16.93 Same result on every version What happened Office had already been successfully activated and worked normally. I was able to: create documents edit documents save documents After restarting the Mac, Office suddenly requested activation again. Since then it has never activated successfully. Initially Office failed to activate with an unknown error. After completely uninstalling and reinstalling Office using Microsoft's installer, the activation process changed. I can now successfully sign in with my Microsoft account, but after authentication Office displays: "No license found for this account." My Office Home & Business 2019 license is still present in my Microsoft account under Services & Subscriptions. Even though my Microsoft account clearly owns Office Home & Business 2019 for Mac. Microsoft account The license appears correctly under: Services & Subscriptions Office Home & Business 2019 for Mac Added to my account on August 7, 2019. The website instructs me to open an Office application and sign in to activate. Everything I've already tried Uninstalled Office completely Installed Office again using Microsoft's installer Installed Office 16.78 Installed Office 16.93 Updated to Office 16.101 Removed Office containers Removed Group Containers Deleted OneAuth cache Deleted Entrabroker cache Removed activation tokens Cleared Office preferences Signed out and signed back into Microsoft account Deleted Office credentials from Keychain Reinstalled Microsoft AutoUpdate Verified no MDM profile exists Verified Internet Accounts Verified Microsoft account Microsoft Support remotely accessed my Mac and repeated all troubleshooting steps Nothing solved the issue. Additional information Running: defaults read com.microsoft.office returns: OfficeActivationLicense = NoLicense although: OfficeActivationEmailAddress = email address removed for privacy reasons is correctly detected. The activation window successfully reaches Microsoft's login page. Office now asks for my Microsoft account credentials. Authentication completes successfully. After a few seconds Office reports: "No license found for this account." It then offers only two options: Buy Microsoft 365 Use another account Microsoft Support remotely connected to my Mac, completely removed Office, installed a newer official installer, and the problem remained exactly the same. My question Has anyone experienced this after reinstalling Office 2019? Could this be: a licensing server issue? an incompatibility introduced after Office 2019 reached end of support? an activation problem related to OpenCore Legacy Patcher? something else? I would really appreciate any suggestions. Thank you very much. Additional notes: The Office license has been associated with the same Microsoft account since 2019. The same installation was successfully activated and worked normally before the problem started. The issue only appeared after restarting the Mac. Microsoft Support has already remotely accessed my computer and could not resolve the problem.
Mac: OneDrive Couldn't Start: Please restart your computer and try again
When OneDrive updated on 9/11, with build 26158.0816, I started to get this error: OneDrive Couldn't Start: Please restart your computer and try again. Error codes: FilterStatus::-3 (0xfffffffd) [Permanent] [SyncRootManagerTools.cpp:128 `Odfs::Fs::CommonPlaceholders::CommonSyncRootRegisterVnop`] I have powered off my Mac and rebooted. Restarting OneDrive does nothing. It keeps giving me this error and as a result, I also cannot live edit docs using the thick clients (Word, Excel, etc). Files I have modified with them are stuck on my Mac. I am looking for tips. Please do not ask me to unlink/de-register all of my Onedrive sync'd shares.
Claude Add-in Error in Excel
Hi Microsoft Community, I'm having an issue with the Claude for Microsoft 365 add-in in Excel for Mac. Environment: Mac Microsoft Excel desktop for Mac Personal Microsoft account (not a work or school account) Claude for Microsoft 365 add-in Excel for the web Issue: When I try to add or use Claude in the Excel desktop app for Mac, I receive this error: “Add-in Error: You don't have permission to use this add-in. Contact your system administrator to request access.” The important point is that I am using a personal Microsoft account, so there is no organizational administrator managing the account. What I've confirmed: The Claude add-in works successfully in Excel for the web using the same Microsoft account. The problem occurs specifically in the Excel desktop application on Mac. This appears to point to an issue with the Mac Office client, add-in authorization, or the Office add-in catalog rather than my Claude account or Microsoft account permissions. I've already tried closing and reopening Excel, but the permission error remains. Has anyone encountered this with Claude for Microsoft 365, or with other Office add-ins, on Excel for Mac? In particular, is there a known issue with personal Microsoft accounts and Office add-ins on the Mac desktop client? Is there a way to reset the add-in/account authorization without reinstalling Office? Thanks.
