Centralized deployment of the signature preview add-in

CodeTwo Email Signatures for Office 365 Add-in can be centrally deployed to all/selected users in an Office 365 organization. In this article, you will find step-by-step guidelines for Office 365 administrators.

There are two ways to perform centralized add-in deployment:

Add-in deployment via Microsoft 365 admin center
(Office 365 admin center)

Add-in deployment via the Microsoft 365 admin center is the recommended approach because it supports deployment to groups with more than 1000 members, which is not possible in Exchange admin center.

To deploy the add-in to users/groups via the Microsoft 365 admin center, you need to be a global admin of your Office 365 organization. Learn more about admin roles in Office 365

First, you need to log in to Microsoft 365 admin center and go to Settings > Services & add-ins. Click the Deploy Add-In button (Fig. 1.).

A new window appears. Click Next and choose I have a URL for the manifest file. Type one of the following addresses:

  • https://emailsignatures365-addin.codetwo.com/InstallApp - if you use the global version of the software
  • https://emailsignatures365-addin.codetwo.de/InstallApp - if you use the Office 365 Germany version of the software

Important

Make sure to provide the URL for your version of the software. Otherwise, signature previewing will not work.

Click Next to see more information about the add-in, and proceed further by choosing Next again. Now, you can configure how the add-in will be deployed to assigned users (Fig. 2.). Select the deployment scenario that best matches your preferences and click Next. (Note that if you choose the Optional, disabled option, each user will have to turn on the add-in manually.)

Finally, assign the users who will get the add-in (Fig. 3.) and click Save to save the manifest file.

You need to wait up to three minutes for the manifest configuration to finish. You will be notified when the add-in assignment is complete (Fig. 4.).

Important

The add-in might not be visible for all of the users right away. The deployment usually takes a few minutes, but might take longer depending on the number of users. Some users might need to restart their Outlook to see the new add-in.

You can close the add-in deployment window now or click Next to learn how to announce the add-in to users. Either way, the add-in is now visible in your Microsoft 365 admin center (Fig. 5.).

Once the add-in is deployed to Office 365 users, they will be able to display the add-in pane with a signature preview while composing emails in Microsoft Outlook, Outlook for Mac, or Outlook on the web (Fig. 6.). See this article to learn more.
