How to Fix “Upload Blocked. Sign In.” in OneDrive

Some users reported having issues when trying to upload files to OneDrive. As they try to save a file or folder to OneDrive, they get an error that says that their OneDrive upload is blocked. Some error messages go into a bit more detail, stating that the user experiencing the error needs to register. However, no further information is given as to why the error occurred and what you can do to solve it.

If you are running into this issue when using OneDrive, it’s a good thing you are reading this post. Below, we will look into how to resolve “Upload Blocked” in OneDrive. Plus, we will also introduce you to a file sharing solution that is much more hassle-free and might just be a better fit for your file sharing needs.

Let’s get started.

Why Is My OneDrive Upload Blocked?

Before we get into what you can do to get rid of this problem, let’s see what causes the error “Upload blocked. You need to sign in”. There can be several things at play here.

First, it may just be a OneDrive glitch. In this case, simply updating to the latest Windows version on your PC should be enough to get rid of the error.

Another possible reason is that the Office application you are using is not participating in the synchronization process. In this case, you will need to configure your OneDrive installation so that you can use Office applications when you need to sync Office files.

You could be running into the error message due to incorrect credentials making OneDrive require a connection over and over again. What you can do here is try deleting the saved credentials via Credentials Manager and then adding them again.

The problem can also occur if you have a suspended OneDrive account on your PC. If you believe that this is the reason for the error, simply remove the suspended account and then add it again.

Yet another reason for the error message could be improperly cached data stored in the Microsoft Office Upload Center. If you suspect that this is the cause of the error, head to the Microsoft Office Upload Center and delete all cached files via the Options menu.

If your PC is part of a connected domain, you may be constantly seeing similar pop-up errors when a corrupted registry value prevents OneDrive from checking your account. In this scenario, you can go on to delete the keys causing the problem.

As you can see from all of the above, there are quite a few reasons why the OneDrive upload error may occur. So, how to unlock OneDrive on Windows?

How Do I Fix “Upload Blocked” in OneDrive?

As we’ve mentioned above, there are several potential solutions you can try here. Let’s review them in a bit more detail.

Option 1: Update your system

Windows updates tend to solve a lot of bugs and glitches — and the OneDrive upload error you are dealing with here is not an exception. So, the first thing you should do is make sure you are running the latest version of your operating system. Here’s how:

1. On your keyboard, use the Win + X combo — this will bring up Settings.
2. Select Update and Security.
3. Click Windows Update.
4. Go to “Check for updates”.
5. Give your system a few seconds as it checks for updates.
6. If any updates are found, follow the on-screen instructions to install them.
7. When the process is complete, restart your PC.

Option 2: Sync your files with Office

If your Office files are not synced to OneDrive, it could be throwing up the error in question. Here’s what to do:

1. Go to the Windows 10 Taskbar.
2. Right-click the icon for OneDrive Cloud.
3. Navigate to Settings.
4. Go to the Office tab. When you see the option that says “Use Office applications to sync open files”, check it.
5. A new window will open. Here, check the option that says “I can choose to merge changes or save both copies”.
6. To apply the changes, click OK.
7. Restart your PC.

Option 3: Clear the cache via the Microsoft Office Download Center

As we’ve explained above, incorrectly stored cache files could be causing OneDrive to show error messages. Deleting the cache can help. Here is what you should do:

1. Go to the Cortana search bar.
2. Type “Office Download Center” and select the first option from the list.
3. On the main page, go to Settings.
4. Scroll until you find the Cache Settings option.
5. Select “Clear cached files” and follow the prompts on your screen to complete the process.
6. Restart your PC.

Option 4: Disconnect your PC from your OneDrive account

Finally, if none of the above solutions have worked, try disconnecting your PC from OneDrive:

1. In the notification area, right-click the icon for OneDrive Cloud.
2. Go to Settings.
3. Click the Account tab.
4. Next, go to “Pick up this PC”.
5. Confirm that this is the action you want to perform.
6. Restart your computer.

However, if you feel like you run into glitches and bugs on OneDrive way too often, you may be happy to learn that there are other options. In fact, there is this new service for sharing large files and folders online that you should absolutely try out. It’s called FileWhopper.

So, what’s so great about FileWhopper? Several things, actually.

First, FileWhopper is one of the very few file sharing solutions that let you transfer files of absolutely ANY size. And we mean any. Even if you have a 10 TB photo album to send, FileWhopper will transfer that folder for you quickly and securely.

This tool is a great time saver too — you won’t need to bother with compressing your files or splitting your large transfer into several small ones. You simply send your file as it is, and that’s exactly how it arrives at its destination.

Second, FileWhopper won’t ask you for a subscription — while most cloud sharing services, like OneDrive, will. With FileWhopper, you pay only for what you are sending — and your total fee only depends on the size of the file or folder you are sharing. What’s more, you can also choose who will pay for your transfer: it can be you or the person you are sending your file or folder to. For a lot of people, this may be a much more convenient – not to mention budget-friendly – way of sharing data online, as you won’t be “forced” to commit to a long-term service that you may just end up using from time to time.

Third, sending data with FileWhopper is 100% safe. This is because FileWhopper uses zero-knowledge encryption, the most advanced form of data protection available today. With it, nobody (except for you and your recipient) will be able to access your data.

When you make a transfer with FileWhopper, you will also need to set a password or choose to have one generated automatically. In any case, your password won’t be stored on FileWhopper’s servers —  and nobody will have access to your data without it.

Another great thing about FileWhopper is that you don’t have to wait for your file or folder to fully upload. You can immediately share the download link with the recipient, and they can start the download as you are still uploading your data.

Even though FileWhopper can do a lot, it won’t bother you with complicated features. It keeps things simple and lets you get the result you want without spending time figuring out how things work or reading lengthy tutorials.

On the other hand, there are extras on demand, and you can get them if you need them. For instance, if you want to send your file to more people, you can. Or, you can choose to store your file or folder on FileWhopper’s servers for longer.

Having your transfer interrupted is definitely annoying. This is why FileWhopper makes sure the damage from this is minimal. If a connection failure occurs, your transfer will simply pause and then resume when things get back to normal. No data will be lost, and you won’t have to start from scratch.

Finally, as FileWhopper doesn’t sync your files, you get to avoid errors and glitches associated with syncing. Sending files and folders with FileWhopper is easy, safe and error-free.

Last but not least, your first transfer of up to 5GB is totally free — so you can try out all of the features we’ve described above and see if FileWhopper is a good option for you without paying a penny.
