Office identity or certificate does not match

Steps

1. Check that the saved address still points to the intended office host rather than a replacement computer or another service.
2. Ask whether the office app data, certificates or Windows profile were replaced. Compare app versions and the timing of the change.
3. Preserve local pending work with a backup. Do not delete the pin, disable certificate checks or paste a new code over uncertain data.
4. Have the administrator verify the host identity and plan recovery/re-pairing. If the Windows clock is clearly wrong, correct it through normal Date & time settings and retry; this does not resolve a genuine identity mismatch.

Check that it worked

The verified original office identity is restored or a controlled migration preserves all unsynced work.

Still stuck?

If these steps do not match your screen, check Company & settings for your version and whether you are using Demo, a field laptop or the office workspace. Search the displayed error or save a support report.
