This message is associated with Microsoft 365 Roadmap ID 82662.

When this will happen:

Targeted Release: We will begin rolling this out in end July and expect to complete by end of August

Standard: We will begin rolling this out in mid-August and expect to complete by late September

GCC: We will begin rolling this out in early September and expect to complete by early October

GCC High: We will begin rolling this out in early September and expect to complete by early October

How this will affect your organization:

To change your default setting, go to your profile picture then select Settings > General>. Scroll to the bottom of the general section to Files. There’s a dropdown menu where you can choose between Teams, Desktop app, and Browser. The default location is the Teams app. The option to choose Desktop app is only available when using the Teams desktop app for Windows or macOS and only applies to that device. If you’re only using Teams on the web, you’ll be able to choose between Teams and Browser.

You can manually choose where a file is opened without changing your default setting by going to the file and selecting More options … > Open in.
