How To Fix OneDrive error code 43?

There are several ways you can fix this error code on your device. We have scouted the fixes from all the different sources possible so that you can access them all in one place instead of looking all over the place.

In this section, we will discuss all the fixes in detail.

Fix 1: Check your internet connection

Since the data you are looking for is not saved on your device, you need to get connected to the Microsoft server in order to get access to the files.

To connect to the server, you need a stable internet connection, especially in cases where you are looking for heavy files or apps.

If your internet connection is lousy and you are aware of the fact, consider switching the networks or fixing the issues with your connection.

Once you solve the issue with your internet connection, it might solve the error code. If there are any other underlying issues and this did not solve them for you, look for the other solutions on the list.

Fix 2: The file name contains special characters

The file name will not be found easily if it contains special characters in the name likely brackets, commas, asterisks, and so on.

You get the idea.

These elements in the file name confuse the search and hence, you will need to manually look through the list of saved files and then change the name to eliminate the special characters. This will not help you in the search this time around but it will help you in the future.

Fix 3: Microsoft OneDrive could not connect to the Microsoft servers

Since the data is stored on the Microsoft server, it is very important that there is a steady connection to the server.

While this is mostly the problem when your internet connection is weak and we have already discussed that before.

However, occasionally the problem might lie with the Microsoft server being down. If the servers are down, you will not be able to establish a connection.

Raise a support request on the official Microsoft website for the problem to be solved as there is nothing you can do on your end if the server is down.

Fix 4: The browser is not allowing a connection to the Microsoft server

Since this problem is specific to Macbook computers, it is likely that your primary browser is Safari which may sometimes refuse to support the connection to the OneDrive server.

This is not a Safari-specific problem though and you may face this problem on other browsers too.

Try to use another browser to access the file and if you can access the file there, it is likely that the issue was with the browser.

Fix 5: You accidentally deleted the files that you are looking for

Sometimes you need to remember if the files that you are looking for even exist. These are instances where you might accidentally or absent-mindedly delete the files that you are looking for.

This becomes a problem when you look for it later but cannot find the files.

Make sure that you take care while deleting the files that you may need some time in the future.

Fix 6: There are multiple duplicate OneDrive versions in the Applications folder

When you download OneDrive on a Mac computer, you need to regularly update the version that you have.

Sometimes, this created multiple duplicate files for the same program and the version that you pick for launching might not have the file that you are looking for.

To make sure that you do not face this problem, you need to open the applications folder and look at the number of OneDrive folders that you can find.

Delete all the versions and reinstall a fresh copy. Log in to access the files on your account.

Fix 7: Contact the Support team

If none of the solutions have worked for you, you can always contact the support team. In this case, you have an additional advantage as not only Microsoft support can help but you can also contact Apple support to help with the same.

The user communities are also always present to help. You can just raise a support question and other users will help you with their experiences.


Do not panic when you see the error code 43 on OneDrive. It does not mean that your files are permanently lost. In many situations, it is just hidden from your view and you need to apply easy fixes to get the file access back.

We have included a list of all the solutions that can help in this situation. Hopefully, you will not need to look elsewhere for solutions.
