For years I have been able to save documents and powerpoints to onedrive flawlessly until about 2 months ago.

I updated the Office 365 and now I always get the "Upload Blocked: We ran into a problem with this file and cannot save any new changes. Please save a copy to avoid losing your work"

I have tried all the disconnect and reconnecting account recommendations, update all OS and Office products. There is an issue that happened in the last update of Office or Onedrive. \

When will Microsoft fix this known issue?

Microsoft 365 and Office | OneDrive | For business | Windows

    Hi fal wil,

    I understand why you suspect the update, especially since this started after years of working normally. However, I could not find a current Microsoft advisory confirming this exact “Upload Blocked” error as a known Office/OneDrive issue with a published fix date.

    Since reconnecting the account and installing updates did not help, first save affected files locally to avoid losing changes. Because this is OneDrive for Business, I would also ask your Microsoft 365 administrator to check Service Health and open a support case with Microsoft, including your Office and OneDrive version numbers and the exact error.

    I would not keep disconnecting/reconnecting OneDrive, as you have already ruled that out.

    Thank you, and feel free to respond back for more assistance.
