OneDrive Business Account can't connect (0x8004e4c3)

Question

Since yesterday, seemingly out of the blue, my OneDrive Business accounts stopped syncing on both my PC and my Laptop. After signing out I cannot sign back in and get the error code 0x8004e4c3, and the error no network connection [2603].

I'm using Windows 11 Build 22000.795 and the latest OneDrive version.

Same problem as here:

Clearing the cache and reinstalling OneDrive didn't help. Neither did disabling the firewall or my windows defender. Again, I could connect to my personal account but not to the institutional account.

TLS 1.0, 1.1, 1.2, and 1.3 are enabled. Still doesn't work.

Any help would be much appreciated, my workflow is currently majorly impaired.

Answer 1

yep, I think it's corruption in the profile. upon making another account on my computer it's OK. Just a hassle to move all my profile stuff over manually, and don't want to move whatever is corrupted. probably something in the registry.

Answer 2

you can make a new profile and disconnect your m$ account from the old one... then setup OneDrive... it should work. Then reconnect your m$ account to the new profile. I am not on a domain, so just made another user with almost my same name.

Answer 3

Had this exact issue this morning on a domain joined computer. Had full network connectivity and I could navigate to anywhere on the web I needed to. I could even use teams. Just Outlook and OneDrive said "no network." Blew away the users' profile and let them log in again. That fixed the issue.

Answer 4

New Windows Profile can resolve the issue
