Available on the Teams and Enterprise plans. This is an organization-level integration, configured by an admin.
The Outlook Signature integration delivers your Wave email signature into Microsoft Outlook via the Wave Outlook Add-in. When a user composes a new email, the add-in fetches their personalized Wave signature and inserts it automatically. This works with Outlook on desktop, web, and mobile.

​
How to Connect

1

Open the integration

Go to Integrations → Outlook Signature (admin only).
2

Grant admin consent

Click Connect and grant admin consent via your Microsoft account. Wave stores your tenant ID to validate future add-in requests.
3

Install the add-in

Install the Wave Outlook Add-in in your Microsoft 365 tenant (via the Microsoft 365 Admin Center or AppSource).
4

Assign the add-in

Assign the add-in to the relevant users, or deploy it organization-wide.
Wave requests permission to verify the tenant admin identity.

​
How Signatures Are Delivered

Unlike the Gmail integration, signatures are not pushed to Outlook’s settings directly. Instead:
  • When a user opens a New Email in Outlook, the add-in calls Wave to fetch their personalized signature.
  • The signature is rendered from the user’s live Wave profile and inserted into the email body.
  • If the render as image option is enabled, the signature is converted to a screenshot image and inserted as a picture, useful for maximum visual consistency across email clients.
Direction: Pull (the add-in fetches from Wave on compose) When: Each time a user opens a new email in Outlook

​
Features

  • Live rendering: signatures always reflect the user’s current Wave profile.
  • Render as image: an optional mode that converts the HTML signature to an image for cross-client, pixel-perfect consistency.
  • Automatic cache clearing: the signature cache is cleared whenever team or template settings change, so users always get the latest version.

​
Limitations & Requirements

  • The Wave Outlook Add-in must be installed in your Microsoft 365 tenant.
  • Users must be assigned to a Wave team that has a signature template set up.
  • This is an organization-level integration. Individual team members do not connect separately.
  • Requires Microsoft 365 with Outlook (Exchange Online). On-premise Exchange may have limitations.

​
Disconnecting

Go to Integrations → Outlook Signature and click Disconnect. This removes the integration. The add-in stops fetching signatures, but it remains installed until removed by the tenant admin.
