Basware Purchase-to-Pay (P2P) will no longer support Internet Explorer 11 (IE11)


Starting from the release 23.12, Basware Purchase-to-Pay (P2P) will no longer support Internet Explorer 11. The decision to end the support was made to ensure the best possible user experience and maintain the highest level of security for our customers.

Internet Explorer 11 is an outdated browser that is no longer actively supported by Microsoft. We understand that some users may still be using Internet Explorer 11, and we apologize for any inconvenience that this may cause. To ensure uninterrupted service, we recommend switching to a modern browser.



On May 19, 2021, Microsoft announced that starting June 15, 2022, Microsoft will gradually transition users from the unsupported Internet Explorer 11 (IE11) desktop app to Microsoft Edge. The out-of-support IE11 desktop application was permanently disabled on certain versions of Windows 10 on February 14, 2023 through a Microsoft Edge update. The IE11 desktop application is not available on Windows 11, and Microsoft Edge is the default browser for Windows 11.
