Dynamics 365, inside Gmail.

No. It is a Gmail add-on, built on Google's add-on framework. That is why it runs on mobile and in browsers other than Chrome.

Only in the background. Dynamics can sync email from a Gmail mailbox at the server level, but that gives your team nothing on screen: no record beside the message, no one-click logging, and no way to create a contact or case from an email. Unaric Sidebar is the in-inbox part that server-side sync does not provide.

The sidebar itself is a direct connection between the mailbox and Dynamics. Nothing is processed or stored by us, and the sign-in token sits in the Google application framework on the user's own account. Automatic synchronization is a separate, optional process. When it is switched on it holds an encrypted access token, email content passes through in transit and is not retained, and it stores only minimal metadata for each item: the syncing user, the email subject, the upload result, and the record ID or error message. It does not store email bodies or the sender's address. An optional troubleshooting log deletes anything it captures after 14 days.

The sidebar has no backend to host, since it connects the mailbox to Dynamics directly. Automatic synchronization runs on a Unaric backend service. New deployments run on Microsoft Azure, and the region can be aligned to your data-residency requirements. The backend also supports AWS, which is where some existing deployments run.

No. The sidebar works on its own, with your team logging what they choose to log. Automatic synchronization is a separate setting your administrators control, and it can be left off or restricted to particular groups.

There is no server to install and no per-object build. A license is configured with your user count and email domains, an administrator approves the connected app once, and each user then signs in with their own Dynamics credentials.
