Upload Blocked error keeps recurring

Question

I have Microsoft 365 for Mac and am using OneDrive to sync my files. When using Word I am very frequently getting an error that says "Upload Blocked" We couldn't verify you have the necessary permissions to upload the file." Recently I have started getting another error that says "Error - Something went wrong and we can't apply the label to this SharePoint or OneDrive file right now. Please try again later or download the file to your computer." Usually the second "error" will not reappear after i close it but the Upload Blocked error reappears every time i save the file to my OneDrive folder.

I have saved copies of files per the Upload Blocked error and get the same error on the saved copy.

I have deleted One Drive and reinstalled it. The problem persisted.

I have disconnected my Microsoft 365 account from One Drive and then reconnected it. The problem persisted.

I have reset One Drive using the ResetOneDriveAppStandalone.command

I have only one Microsoft 365 account that is associated with my email and I have confirmed that I am logged into that account when I am getting this error. I am the only user of my MS 365 subscription (meaning I don't have anyone else in my "organization").

I have attempted the steps suggested here: https://answers.microsoft.com/en-us/msoffice/forum/all/upload-blocked/7009c27f-4abc-4cbd-af40-3a159284d204

For this troubleshooting suggestion: "a. Try to backup the content which is not synced to the cloud by saving the Excel as a different file to the desktop location.

b. Quit all Office apps except Excel> Sign out from the Excel app> Quit the Excel app as well

c. Open the Finders> Applications> Utilities> Keychain Access> Remove all the credentials related to Microsoft Office

d. Restart your Mac> Open the Excel app> Sign in with the Office account> Open the Excel and check whether you can upload without any problem."

I went to Keychain Access and searched for "microsoft". I tried to delete entries related to "passwords" but they did not delete. Also, I do not know what the agent means by "credentials" since that is not a term used in Keychain Access.

I also tried to find the checkbox "Use Office applications to sync Office files that I open" suggested in the linked answer. Currently, when I go to preferences for One Drive there is no tab that says "Office". In the past I had seen that checkbox but since i reinstalled One Drive it no longer appears.

I also followed the steps to remove my license files and reactivated them. The problem persists.

Details:

Microsoft Word for Mac version 16.72

Microsoft OneDrive version 23.071.0402.0001 (Standalone)

License: Microsoft 365 Subscription

MacBook Pro 2.4 GHz Quad Core Intel Core i5

MacOS Ventura 13.3.1

Dear A Gold,

Good day! Thank you for posting to Microsoft Community. We are happy to help you.

As per your description, it seems that you are having issue using OneDrive synced files in Word, error prompts and you have already tried reinstalling OneDrive, delete entries in keychain, clear credentials and remove license files and then reactivate them.

If the understanding above is right, as per the error message you are getting, we'd recommend you refer to below suggestions and hope they can help:

1. Unlink and re-link OneDrive - Microsoft Support
2. Reset OneDrive - Microsoft Support
3. Reinstall office, for your reference: Download and install or reinstall Microsoft 365 or Office 2021 on a PC or Mac - Microsoft Support
4. At meantime, to confirm if the problem is caused by the local environment, we'd also recommend you create a new user profile on Mac and see if any improvement. It is worth trying because it will help narrow down whether the issue is caused by a specific corrupted user profile. ***Third-party link disclaimer:***Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites, or any support related to technology.

For the checkbox "Use Office applications to sync Office files that I open", we've also done a quick test, and we can reproduce a similar situation on our side, no Office tab showing up in OneDrive >

Preferences. We've done a lot of searches and we can't find an official article that has documented this situation. More resources need to be involved in.

If the issue still persists or you want to know more about Office tab in OneDrive sync client, as you mentioned that you are the only user of your M365 subscription, we notice you post this question in For business category, so we suppose you have Microsoft 365 for business subscription, and you are the administrator. In this situation, we sincerely recommend you follow steps in this article to contact Online Support. The support team over there has higher permission than us, they can remotely help check the situation on your side, involve more resource to collect logs and help you do troubleshooting. This would be a more efficient way in handling this case for you.

For reference: How do I find my Microsoft 365 admin?

If our understanding of the scenario is not consistent with yours, feel free to point it out.

Thanks for your understanding and cooperation! Have a good day.

Sincerely,

I am having a similar problem with upload blocking. I spent the afternoon working on a file and then began having this problem. I tried some of the options listed by A Gold, but not all. Today, the most recent version of the file is about an hour old and it appears that my final document is lost.

I am at a university and all employees have OneDrive through the university.

I might have found a fix. Before I had tried all the same steps as well and had identical two banners on Word.

• Open MS Word, click Word -> Sign out -> Quit MS Word. Launch again.
• I accidentally typed wrong University email (not sure if this has any impact, but I mention it as it usually has saved the login credentials for currently active MS account and this could have reseted something), clicked sign in, corrected email, entered password and signed in.
• For me it asked for permission to access CloudStorage folder, which I granted as it contains OneDrive folder
• Interestingly, it showed that my MS365 subscription does not support Word for Mac. I clicked Word -> Activate, it did the rest itself more or less.

Now all the files open without problem and the sync works, except for one document which shows that I have read-only access.
