Frequently asked questions
›Which Outlook clients are supported?
Modern Outlook for Microsoft 365: new Outlook for Windows, classic Outlook for Windows (Microsoft 365 Apps), Outlook for Mac, Outlook on the web, and Outlook for iOS and Android, with Exchange Online mailboxes. Mail sent from other apps or devices is not signed.
›Does any of our data reach KamSoft?
No. Settings, templates, images and directory details stay in your Microsoft 365 tenant. The add-in and portal connect only to Microsoft, enforced by Content Security Policy.
›Do users need to install anything?
No. An administrator deploys the add-in centrally from Microsoft 365 admin center → Integrated apps. It appears for users automatically.
›What happens if SynaMark is unavailable?
Outlook inserts the user’s most recently cached signature, or a plain-text fallback with their name and email. Composing and sending are never blocked.
›Why do users’ own signatures disappear?
To enforce a single governed signature, SynaMark disables the Outlook client signature while a SynaMark signature is applied.
›How quickly do directory changes appear?
SynaMark reads Entra ID live, so changes appear the next time each device refreshes its cached signature (within an hour by default).
›How do I remove SynaMark?
Remove the add-in in Integrated apps, cancel the subscription in Microsoft Marketplace, and delete the SynaMark SharePoint site if you no longer need it. Your data was always in your tenant, so there is nothing for us to delete.
