Default PDF reader in Outlook

Solved

Hello everyone,

I have an unsolvable problem despite several hours of research on forums...

In my Outlook application, when I double-click on a .pdf attachment, the default program choice window always opens. No matter how many times I select Adobe Acrobat Reader DC and check the "Always use this app to open .pdf files" box, I get asked again every time.

I want to prevent Outlook from asking me every time I open a pdf file.

In the default apps settings, I have set .pdf files to open with Adobe; in fact, if I open a pdf from the file explorer, it opens directly with Adobe without any issues. The worst part is that Outlook "knows" what my default program is because in the "How do you want to open this file" window, it first shows "Continue using this app" with Adobe below, then "Featured in Windows 10" with Microsoft Edge, followed by "More options" with my other compatible programs.

I thought it might be a way for Windows to push users towards Microsoft Edge, but after setting my default browser to Edge and opening pdfs with Edge (then restarting the PC), I still get the program choice window in Outlook.

The issue doesn't occur with other extensions (.docx, .xlsx...) where attachments open directly with the default program without confirmation requests (even for extensions related to specific non-Microsoft applications).

I tried changing the default program to Edge and then to another pdf reader (Foxit Reader), but the problem remains the same.

I attempted to "Repair" the Outlook application, which also did not resolve the issue.

I want to point out that I have regularly restarted my PC after each attempt.

Some may say it's just a single click each time I open a PDF attachment, but I open a lot of them at work and any loss of productivity due to unnecessary clicks drives me crazy. I should mention that this is a brand new PC, so I don't have a previous state where the problem didn't exist (other than the fact that the problem did not exist on my old PC with Outlook 2016).

My configuration:

Windows 10 Pro
Outlook application (from the Microsoft Store) - Version: 16040.10325.20118.0
Adobe Acrobat Reader DC - Version: 2018.011.20058


Thank you if you had the courage to read my post to the end to provide me with a relevant response :)

[SOLUTION]: The issue comes from the Office applications from the Microsoft Store. The only current solution is to uninstall them, then reinstall Office directly from the Office page on the Microsoft website (by doing this, there is a warning page during installation that the application is not from the Microsoft Store). This requires retrieving the activation key from your Microsoft account beforehand. Once this process is completed, the programs ask the question once upon opening the pdf, and by checking the box "Always use this application," they no longer ask the question again (phew!).
