Install the add-in

Deploy the ECARD add-in from the Microsoft 365 admin center, check your license compatibility and resolve common issues.

This page is for Microsoft 365 administrators. The ECARD add-in uses the standard Office/Outlook add-in mechanisms and is deployed from the Microsoft 365 admin center.

Microsoft prerequisites

The ECARD add-in is reserved for users with a Microsoft 365 subscription. Centralized deployment requires:

  • a compatible license (see below);
  • an active Exchange Online mailbox;
  • a Microsoft 365 administrator role to perform the deployment.

Outlook must be installed via the license included in your M365 subscription. Some subscriptions don't include Outlook Desktop — on those, the add-in is only available on Outlook Web (OWA).

Deploy the add-in

  1. Sign in to the Microsoft 365 admin center: admin.microsoft.com (or Exchange, depending on your configuration).
  2. Open Settings → Integrated apps (Add-ins).
  3. Click Get apps.
  4. Search for "ECARD", then click Get it now.
  5. Choose the targeted users: the whole organization, defined groups, or specific users. This lets you test before a global rollout, or target specific teams.
  6. Confirm the configuration, then click Deploy.

The add-in can take 24 to 72 hours to appear in every user's Outlook client. Once visible, the signature defined in ECARD applies automatically to new emails.

Compatible licenses

Centralized deployment requires a compatible license AND an active Exchange Online mailbox. The Outlook web only note flags licenses that don't include Outlook Desktop.

Common issues

A user has no access to the add-in, even after 72 h

  1. Check they belong to the group or the targeted users of the deployment.
  2. Remove them then add them back to the user group to trigger a new deployment.
  3. Restart their computer to force Outlook to clear its system cache.
  4. If the problem persists, contact Microsoft support directly.

The add-in is present but no signature is inserted

  1. Open the add-in panel and check whether an error code appears.
  2. Check that the user has an active profile in ECARD and an assigned signature.

If a network error message appears, see Network configuration. For rendering problems, see Signature troubleshooting.
