Completely unhelpful reply.
Whoever built this Outlook "browser" didn't test it properly....
If the link in the email is a notification for a 3rd-party app (eg Strava, and others) then the "Open in Browser" option mentioned above doesn't work. Instead of opening the (already installed) app, the "Open in Browser" button takes me to the Play Store,
to install the particular app. You know, the one which is already installed.....!!!
I can put up with having to use the extra button to transfer web pages from Outlook browser to Chrome etc, but there doesn't seem to be a useable workaround for 3rd-party app notifications.
I use Outlook as a "hub" for emails, incoming notifications, calendar events etc (also full Outlook on 2 PCs) but this screwup could well change that.
NEED a setting option to disable this functionality. Along with a slightly less arrogant mindset & attitude from the support team!!!
