Unable to Open Word Docs via "Open in App" within Teams
Hi Shannon2475
Were you trying to open Word files in Teams and it fails to call Word desktop app? As far as I know, when you try to open the files in desktop app, it will use the URL protocol to open the related Office desktop app. In this scenario, please go to Settings > Apps & features > Default apps > Choose default apps by protocol, then scroll down and check if Word is selected as the default app for MS-WORD.
If that doesn’t help, please first make sure your Office apps are updated to the latest version. If it's already the latest version, please try to run https://support.office.com/en-US/Article/Repair-an-Office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b to check if it helps.
Kindly post back if I misunderstood the issue you reported.
Best regards
