End of support for IE11 & Edge Legacy for OnePlaceMail App
Following the official Microsoft retirement and end of support for both Internet Explorer 11 (June 15 2022), and Microsoft Edge Legacy (March 09, 2021) OnePlace Solutions will end support for both Internet Explorer 11 and Edge Legacy on March 31, 2023
After March 31, 2023 users who access the OnePlaceMail App using a version of Outlook on Windows that uses Internet Explorer 11 or Edge Legacy will not be able to use the App and will see a message requesting them to upgrade Outlook.
Why are Outlook Add-ins and Internet Explorer/Edge Legacy linked?
- The version of Windows
- The version of Outlook
- Whether Outlook is a Microsoft 365 subscription installation or a perpetual Outlook installation
- Within the perpetual versions of Outlook on Windows, whether the Outlook installation is "retail" or "volume-licensed" variation
The combination of these can get quite complicated and Microsoft has provided this guidance on establishing which browser is used to host Outlook add-ins.
What do you need to do?
If your Outlook for Windows installation is using Internet Explorer 11 or Edge Legacy and you wish to continue to use the OnePlaceMail App, you must either;
- Upgrade Outlook for Windows to a version that uses Chromium based Edge
- Access your email using Outlook on the Web (OWA) via a supported browser such as Chrome, Safari, Firefox, and Edge (Chromium-based). The OnePlaceMail App will continue to be available in OWA.
