Links from Microsoft Teams no longer open in the expected browser

[marcoskirsch]

This used to work, but Microsoft must have changed how they launch URLs.

Before: links would go to Finicky and open in the expected browser.
Now: links presumably go to Finicky but always open in Safari and Safari stays in the background.

Have you tried creating configuration for this application?

I tried changing default browser to Edge, and links from Teams correctly opened in Edge and Edge came to the foreground.
I tried changing default browser to Safari, and links from Teams opened in Safari and Safari stayed in the background !
I tried changing default browser to Finicky and the same incorrect behavior remained.

What application are you trying to set up

I want to click links on Microsoft Teams and have them open in the correct browser per my configuration, which works correctly from other applications including Microsoft ones.

Perhaps if there is a log on what Finicky processes it may shed some light?

It looks like Teams opens links to a safe-link checker (maybe this is dependent on the organisation)

I seem to be able to redirect all links by matching https://statics.teams.cdn.office.net/*

If it helps, this has stung me a bit. When you add a Teams meeting to a calendar invite it now comes with two links, both wrapped in safelinks. The first opens the Teams help page redirect and the second opens the actual meeting. I've found a bunch of tools (BusyCal was one example) are configred to grab the first link in a meeting invite, meaning you always ended up at the redirect page. I initially assumed this was Finicky enable to untangle the link in the safelinks but discovered this twist too.

What's the process to expose the secondary link then?

I've got the logs by running: /Applications/Finicky.app/Contents/MacOS/Finicky --dry-run --window and I see that the origin/destination urls are encoded there.

Here is an example that works for v4:

export const msTeamsHandlerEgress: BrowserHandler = {
  match: (url: URL, { opener }) => {
    return (
      opener?.bundleId === MSTEAMS_APP.bundleId &&
      url.host === 'statics.teams.cdn.office.net' &&
      url.pathname.startsWith('/evergreen-assets/safelinks/1/atp-safelinks.html')
    );
  },
  browser: FIREFOX_APP.bundleId,
};
