Edge browsers cannot sync on different devices due to email name change on same account.

Hello,

Have you confirmed the desktop is signed into Windows using the same updated account email?

A direct fix is to remove and re-add the work or school account connection used by Edge sync.

Go to Windows Settings, Accounts, Access work or school, select your account, then Disconnect. Restart the PC, go back to the same section, add the account again using the new email, then open Edge and turn sync on under Profiles.

This refreshes the account token at the system level and restores sync without exporting data.

Edge sync is tied to the Microsoft account identity that the profile is currently signed in with. After an email alias/name change on the same Microsoft account, the affected Edge profile must be signed back in so it can re-establish sync with the updated account identity.

To get the desktop profile syncing again (and keep using the same underlying Microsoft account):

1. On the desktop, open Edge and go to Settings and more > Settings > Profiles.
2. In the problem profile (showing “sync is not available”), select Sign out.
   • Edge will warn that signing out stops sync. This is required to reset the profile’s connection to the account.
3. After signing out, in the same Profiles page, either:
   • Select the existing profile and choose Sign in, or
   • Create/choose a profile and sign in with the Microsoft account that now uses the new email name.
4. Once signed in, go to Profiles > Sync and turn on the data types to sync (favorites, passwords, history, etc.).

As long as the same Microsoft account is used (just with the updated email name), Edge will sync the existing cloud data from that account back to the desktop. Manual export/import is only needed if choosing not to sign that desktop profile back into the Microsoft account.

If sync still shows as unavailable after signing in with the updated account, verify sync settings and status:

1. On desktop Edge: Settings and more > Settings > Profiles > Sync.
2. Ensure the toggles for the desired data types are turned on.

Sync will then work across devices (desktop and laptop) using that same Microsoft account.
