Microsoft 365

Custom Client ID

To setup a custom client ID, you must register a new application with Microsoft and enable the appropriate permissions.

1. Sign up and/or login to Microsoft Entra
2. In the sidebar select "Identity" → "Applications" → "App registrations"
3. In the tab bar select "New registration"
4. Choose a name for the application and select "Accounts in any organizational directory (Any Microsoft Entra ID tenant - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox)". Leave the "Redirect URI" empty and click "Register"
5. Copy the "Application (client) ID" and then click "Add a Redirect URI"
6. Select "Add a platform" and then "Mobile and desktop applications"
7. Under "Custom Redirect URIs" add goa-oauth2://localhost/<client-id>, then click "Configure"
8. Select "API permissions" in the application sidebar, then "Add a permission" in the tab bar
9. Select "Microsoft Graph" and "Delegated Permissions", then add the following permissions:
   • offline_access
   • contacts.readwrite
   • files.readwrite
   • files.readwrite.all
   • mail.readwrite
   • sites.read.all
   • sites.readwrite.all
   • user.read
10. Click on "Add permissions" to complete the process

    Unfortunately, M$ is about profit not ❤️ for Linux.

You cannot login to Admin Center with a personal account.

OK, I was a bit harsh with my strikethrough remark. That limitation may apply if you want to register your own app.

The real issue is the counterintuitive UX with the dialog that pops up when the user selects Microsoft 365 in GNOME's Online Accounts. You don't need all those steps if what you're up to is simply getting access to your OneDrive files via GVfs backend (same as with Google). Here's WHAT YOU NEED TO DO: leave both fields empty (Client/Tenant ID) and hit the Sign in... You'll login as usual with your personal MSFT account credentials (email and password).

For the curious ones, here is where I hit the SPO license wall (when user clicks the related entry in GNOME Files aka Nautilus - it triggers an activation event, resulting in GVs trying to automount user's OneDrive).

I made a screencast (mute) video that should be published shortly.

UPDATE: work in progress. Follow 319.
