Frequently asked questions

Have a question? Here are answers to the most common ones.

An administrator connects your Microsoft 365 tenant to SIGNESTO through Microsoft OAuth. Your users are synced from Entra ID, and each employee then receives in Outlook the signature generated from the template assigned to them.

Yes. Signatures apply in Outlook on Windows, on the web (OWA), and in the Outlook mobile app for iOS and Android.

A Microsoft 365 administrator account is required to authorize the app. SIGNESTO only requests minimal permissions: reading users and groups from the directory, and installing the Outlook add-in.

SIGNESTO does not read or store your emails. Only the information needed for signatures (name, job title, contact details) is synced from your directory, and you can revoke access at any time.

Yes. You choose which users and groups to sync from Entra ID and assign different templates by team, site, or department.

Arrivals, departures, and job changes are picked up at each sync with Entra ID: the employee's signature is updated automatically, with no manual action required.

Deploy professional email signatures across your entire company.
