Edge sync isn't available for this account - Error

For a single Microsoft Entra user seeing “Sync isn’t available for this account” while others can sync, troubleshoot in this order as tenant admin:

1. Confirm licenses
   1. Sign in to the Microsoft 365 admin portal and verify that this user has a valid, supported Microsoft 365/AIP license and that it isn’t expired.
   2. Sign in to the Azure portal and verify that the Azure subscription and user’s Azure license are valid.
2. Verify Edge sync prerequisites for the tenant
   1. Confirm the tenant has one of the supported subscriptions for Edge enterprise sync as described in Configure Microsoft Edge enterprise sync.
   2. Verify Rights Management Service (RMS) is available and active for the tenant. If needed, activate it by following Activating the protection service from Azure Information Protection.
3. Check for RMS scoping and IPCv3
   1. Run Get-AIPServiceOnboardingControlPolicy and verify that RMS isn’t scoped in a way that excludes this user. If scoping is enabled, either add the user to the scoped security group or remove the scope using Set-AIPServiceOnboardingControlPolicy.
   2. Run Get-AIPServiceConfiguration and confirm that IPCv3Service is enabled in the tenant.
4. Enable (or temporarily enable) Enterprise State Roaming (ESR)
   1. If RMS is active and the user still can’t sync, enable Enterprise State Roaming for the tenant as described in Enable Enterprise State Roaming in Microsoft Entra ID.
   2. Test Edge sync for the affected user. If sync starts working, ESR can remain on or be turned off again after confirmation.
5. Validate Edge and profile configuration on the user’s device
   1. Ensure Edge is at least version 98.0.1108.43.
   2. In Edge, go to Settings > Profiles > Sync and select Re-sync data to this device.
   3. If the issue persists, select Still having sync problems? Try another option and then Reset sync for this profile.
   4. Go to edge://sync-internals and verify in the Summary section that sync is enabled and that no identity error (such as EDGE_AUTH_ERROR) is shown under Credentials.
   5. Go to edge://policy and check whether any applied policy is blocking sync for this user.
6. If still failing
   1. Confirm again in edge://sync-internals that the status shows DISABLED_BY_ADMIN or similar; if so, the cause is almost always tenant configuration (steps 1–4).
   2. If all checks are correct and the user still cannot sync while others can, collect logs from edge://sync-internals and open a case with Microsoft Edge support.
