How to switch from deprecated preview add-in to modern Web Add-in

Problem:

You are using CodeTwo Email Signatures for Office 365 Add-in to preview cloud (server-side) signatures in Outlook. Since the add-in is no longer supported, you would like to move to the modern Web Add-in to ensure the best experience for your end users.

Solution:

The switch between the two CodeTwo add-ins is simple and can be completed with no downtime for end users. To perform the switch, you need your tenant’s Microsoft 365 global admin account.

  1. Deploy the modern Web Add-in
  2. (Optional) Inform your end users
  3. Uninstall the deprecated preview add-in

The modern Web Add-in experience

CodeTwo Signatures Web Add-in for Outlook and OWA not only lets your users preview what their cloud (server-side) signature looks like when composing an email, but also offers you much more in various aspects.

  • The Web Add-in was co-engineered with Microsoft and uses their latest event-based activation technology to ensure better user experience.
  • Ultra-fast company-wide deployment – end users don’t need to touch anything.
  • Additional features when using CodeTwo Email Signatures 365 in Outlook (client-side) or combo mode:
    • Signatures added automatically to new messages and replies/forward as end users type an email.
    • Manual selection of signatures from the Web Add-in’s pane.
    • The ability to switch between cloud and Outlook signatures in combo mode, and more.

(Optional) Inform your end users

Once the Web Add-in is deployed and becomes available in Outlook across your organization, inform your end users about the switch. Make sure your end users can identify the new Web Add-in and know how to start using it. Regardless of an email client, the icon of the modern Web Add-in is easily distinguishable from the deprecated add-in’s icon, as shown in Fig. 1. below:

Uninstall the deprecated preview add-in

The signature preview add-in is deployed per Microsoft 365 user, not per machine, so it will be automatically removed in both Outlook and Outlook on the web (OWA) when uninstalled in one of them, regardless of which method below you choose.

This is the final step to ensure that the deprecated preview add-in is removed from end users’ Outlooks, so that they do not confuse it with the modern Web Add-in. Click a link to continue with the desired uninstall method:
