* (✅ -> ❌) - End of support officially announced.
(1) - Support for running Microsoft 365 Apps (Web Add-ins) on Desktop. Not having the support makes the Email Signature Web Add-in completely not working.
(2) - Support for Task Pane interaction - when opening the "Email Signatures" task pane and manually inserting the signature. We refer to this as authenticated flow in Web add-in, as the user has to authenticate/be authenticated.
(3) - Support for Event-based actions. These include all the actions that are performed by us as a result of user actions in Outlook, without interacting with the Task Pane. We refer to this as an unauthenticated flow, as this works for 30 days after logging in in the task pane. As of now (Oct. 2022) there are 2 triggers: on a message being composed and on recipients being changed. The first one handles the automatic signature insertion, while the second one performs updating the signature for internal/external. Not having support for this makes our Web Add-in only work in authenticated flow.

Module and Library availability in Templafy

You can find more information on what is supported on PC, Mac, or Office Online here:

Check and ProductivityPlus modules in PowerPoint for Mac and PowerPoint for M365 (Web Add-in)

Templafy modules Check and ProductivityPlus are not available with the Web Add-in. Which means that the modules are not available in PowerPoint for Mac or PowerPoint for M365.

With that being said, due to accessibility requirements, building a Web Add-in for those modules is being prioritized by the Templafy Product team. There is no ETA for this functionality. Please contact your Customer Success Manager for an update on the progress.
