【Sync Issue】Edge Sync Stuck on “Setting up sync” on All PCs for One Microsoft Account
Your tests isolate the affected account's desktop sync path: other accounts work on those PCs, while that account works on mobile. That does not prove a server-side fault or guarantee that a backend reset will fix it.
Microsoft documents a sync-recovery path in Settings > Profiles > Sync > Re-sync data to this device. Try Re-sync on one PC first. Before considering Reset sync, export favorites with Ctrl+Shift+O > More options > Export favorites and preserve any other important local browser data.
If resync fails, the “Still having sync problems? Try another option” control provides Reset sync. This resets cloud sync data; keep Edge open until completion and follow the prompts about resuming synchronization.
If that control is unavailable or reset fails, contact Microsoft Edge Support with desktop/mobile versions, timestamps and your comparison matrix. Support must investigate the account-specific failure; the forum cannot perform that reset for you.
