Managing profiles and sync in Microsoft Edge on Windows 10
This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
Hi there, I've had a problem with syncing for quite some time. Earlier this year I had a sync problem that went away, it had to do with authentication and tokens. Today it is back now now with network error. It particularly happens on my MS Surface with Win 11 but does not happen on my Dell XPS with Win 10 or iPhone 13. Last week I fixed the problem by installing the stable version after being on 155.0.4283.24 Beta. A week later running 155.0.4283.45 (Official Build) and the sync problem is back. I have tried repairing edge, re-syncing, Verified DNS resolution works correctly: ISP DNS, Cloudflare (1.1.1.1), Google DNS (8.8.8.8).
Authentication generally succeeds:
Typical startup sequence:
Initial sync requests succeed:
Server response:
Over time the logs repeatedly show intermittent failures:
Current encryption state appears healthy:
This suggests the issue is no longer related to missing encryption keys.
I am out of ways to fix this and it is unsustainable to delete the profile once a day or reinstall edge regularly.

For "Setting up sync..." on the Surface while auth and encryption look healthy, treat this as a connectivity or policy issue, not a token or key issue.
Recommended troubleshooting path:
edge://sync-internals, confirm there is no identity error under Credentials. A valid signed-in account is required before treating this as a sync problem.edge://sync-internals/edge://signin-internals/ and verify the browser sign-in status is healthy on the Surface.edge://policy/ and look for policies that can prevent sync. If the message is "Sync has been turned off by your administrator", make sure SyncDisabled is not set.ERR_NAME_NOT_RESOLVED, ERR_INTERNET_DISCONNECTED, ERR_CONNECTION_RESET, and intermittent 401, verify the device can access these endpoints and that no firewall, proxy, or network filter is interrupting them:
https://edge.microsoft.comhttps://api.aadrm.com for most tenantshttps://api.aadrm.de for tenants in Germanyhttps://api.aadrm.cn for tenants in Chinahttps://*.cloudmessaging.edge.microsoft.com/wss://*.cloudmessaging.edge.microsoft.com/edge://sync-internals is empty, or the endpoint cannot be reached, that points to network or firewall interference on the Surface.edge://sync-internals shows a cryptographer error under Type info, switch to the cloud reset path
If the error appears as:
Error:GenerateCryptoErrorsForTypes@../../components/sync/driver/data_type_manager_impl.cc:42, cryptographer error was encountered
then the documented fix is to inspect Microsoft Entra account Key Status and reset Microsoft Edge data in the cloud if required.
