OneDrive is a handy & popular Microsoft storage space. But it becomes annoying when you can’t log in OneDrive. This fails the sync of your files & folders.
Many others including me encountered a failed login issue. But it’s not complicated to fix.
In this article, I will show the solutions if you can’t sign in to OneDrive. Let’s jump in.
How Do I Fix OneDrive Not Signing In
OneDrive is a cloud service for safely storing crucial data & accessing them from anywhere, including saving local disk storage. The service is cloud-based, so if you fail to sign in, the local OneDrive storage will not connect to the online OneDrive.
Many Windows & Mac users experience OneDrive not signing problems.
So Why is My OneDrive Not Signing In?
Below are some top reasons that prevent logging into OneDrive.
- Unstable internet connection.
- Outdated OneDrive
- Microsoft server connection issue with OS.
- Conflict with security features.
Before diving into the procedures to fix the issue, initially restart your PC & check again. The first time I encountered the problem, my personal OneDrive account was logged in without issue after booting into the system. However, my business account kept looping in sign-in.
I waited for 10–15 minutes, but it was still stuck. I tried to log out & re-login. Yet it was fruitless. Then I restarted my computer & voila! It signed in automatically.
If that doesn’t help, follow the methods below to get rid of OneDrive’s sign-in loop of death.

1. Verify Network Connection
OneDrive is a cloud-based client & it requires a stable internet connection to sign in. If the network is unstable, misconfigured, or services related to it get bugged, it can stall the sign-in.
First & foremost, check you have an up & running network connection. Restart your router as a first troubleshooting. After the router reboots, go to some websites from your browsers & check whether they load the page normally.
If there is an issue regarding connection, type network status in the Windows search menu & go there. In the Status tab, find Network troubleshooter from the right section & click on it. It will try to detect & fix if there are any issues. 
If you still face network issues, contact your internet service provider. Without having a stable network connection, you won’t be able to sign in to OneDrive.
