We are not compatible with Internet Explorer or Edge (Legacy). Compatibility with other browsers may vary. 

Outlook Desktop Versions We Support

To display add-ins in Outlook Desktop, an embedded browser is used. Depending on your configuration, your version of Outlook may not be using a compatible embedded browser. Our add-in is compatible on: 

  • Windows machines with Office versions using Edge (with WebView2 - Chromium-based)
    • Non-subscription Office 2021 or later on Windows 10 or 11
    • Microsoft 365 ver. >= 16.0.13530.20424 on Windows 10 or 11
  • Outlook for Mac

To confirm which browser your version of Outlook uses, please reference the following: Browsers used by Office Add-ins

API Requirement Sets for Outlook Add-ins

In order to Compose secure messages on Web and Outlook Desktop, our add-in requires a configuration that supports API set 1.8. For reading messages, you need a configuration that supports API set 1.5. Since our mobile compatibility is read-only, iOS and Android apps are supported.

Please note: Due to these API requirements, we only support organizations using Exchange Online. We do not support organizations using Exchange on-premises. 

For details on support of API sets by product and platform, refer to the following: Outlook JavaScript API requirement sets

Additionally, our API requirements only support organizations hosted on "Global Azure" which include:

Since our current implementation only supports “Global Azure” this limits us from using the following plans.
