Mail won’t sync — how do I diagnose?

Sync never finishes, the account row shows an error, or you need evidence for IT support.

1. Step 1 — Read the status line

   Hover for detail; often names host, auth, or timeout errors.

2. Step 2 — Verify connection

   From the account context menu, run Verify connection.

3. Step 3 — Open diagnostics

   Collects deeper logs for support or your own IT.

4. Step 4 — OAuth repair

   If Google/Microsoft tokens expired, use in-app re-login prompts when shown.
