Microsoft New Outlook and Templafy VSTO add-ins

About this article

Microsoft has announced an upcoming release that will also impact Templafy customers. The coming release from Microsoft includes a new version of Outlook that does not support VSTO add-ins in the future, which naturally impact the Templafy VSTO add-in along with any other VSTO add-ins. This article will explain the impacts and the potential solutions. 

 

About the Microsoft release

Microsoft has announced a fundamental change to Outlook for Windows and as a part of the release, VSTO add-ins will no longer be supported in Outlook.

The full announcement is posted on Microsoft's Support page:

Additional information is available on the Microsoft Community:

 

 
  • Microsoft is rolling out the release gradually (Office Insiders), but there are no official release date for when the change to the new Outlook will be enabled to all by default. Templafy does not have any control on the timeline set by Microsoft on rolling out to general availability. Until then, the change can be toggled on/off for those who are wanting to enable/disable the new Outlook. 

 

How the Microsoft release will impact Templafy

Templafy has two different add-ins that can be utilized in Outlook:

  • Email Signature
  • Outlook Library 

With the Templafy Hive platform, both add-ins are available as VSTO and web add-ins ensuring a full support of the New Outlook.

On the Templafy One platform, both add-ins are only available as VSTO and will not be supported in the New Outlook

 

How to transition to New Outlook

Customers in Templafy will have various opportunities to transition to the New Outlook, based on which version of the Templafy platform, they are currently on, as well as which Templafy modules are available to them. More information on this, please reach out to your Templafy contact to be presented with the right opportunities for you. 

 

 
  • Templafy recommends distributing the web add-ins for Outlook: 
    • Future proof user experience: only web add-ins will be supported in the New Outlook
    • Minimize future workload: by deploying the Web Add-in to Outlook users today, additional workload once Microsoft pushes the new Outlook can be avoided.
    • Reach the users where they work: access the Outlook functionalities on PC, Mac, and Office Online

 

All the options are described in below table, but it's advised to consult with your Templafy contact to confirm the right opportunity:
