Outlook PWA complicates attachment handling for users

In the transition to the Progressive Web App (PWA) for Outlook, users face challenges with attachment handling. Outlook, which is evolving from a traditional desktop application, now opens attachments through a web browser rather than directly in the native desktop application. This change has been particularly problematic for users accustomed to seamless integration with applications like Excel. In a recent inquiry, a user expressed frustration about not being able to configure the PWA to bypass the browser and instead open Excel attachments directly. The existing method requires users to click on an 'Open in Excel' button, which subsequently launches Excel on the desktop but adds unnecessary steps to the workflow. This behavior not only disrupts productivity but also affects those who frequently handle Excel files in their email correspondence. Further complicating matters, the user searched extensively for settings to suppress this behavior but ultimately found no solutions or relevant assistance. The concern arises from a broader context of shifting to the PWA as the legacy desktop application phases out, prompting users to seek new ways to optimize their experience. Particularly for users who rely heavily on spreadsheets and attachments for their professional responsibilities, this adaptation period is proving to be less than smooth.
