Help needed with Testing Microsoft Copilot Integration

[ksylvan]

I don't have a Microsoft 365 Copilot Enterprise license, but I thought one of you might be able to test this.

The new feature branch is related to the issue:

#1849

Can you try my branch here?

https://github.com/ksylvan/fabric/tree/kayvan/msft_copilot_vendor_by_claude_opus_4_5

git clone --single-branch --branch kayvan/msft_copilot_vendor_by_claude_opus_4_5 https://github.com/ksylvan/fabric.git /tmp/fabric_msft
cd /tmp/fabric_msft
go build -o ./fabric ./cmd/fabric
./fabric -S

And then choose Copilot from the list of providers:

This branch is languishing. Someone with the right kind of corporate subscription needs to test it—alternatively, one of you fine folks can sponsor me with a corporate Microsoft Copilot account and I can test it myself.

@tomstetson Thanks!

Heya @ksylvan - I ran into a couple issues but wanted to share my findings and contribute a fix.
The branch had a build error due to an interface change in main. I've submitted a fix for this.
PR: ksylvan#2

The sendstream interface now expects chan domain.StreamUpdate instead of chan string. The PR updates the Copilot vendor to match. Build passes after the fix.

Here's what works:

• Licenses: Microsoft 365 E3 (SPE_E3) + Microsoft_365_Copilot license confirmed
• API Endpoint: /beta/copilot/conversations is accessible in my tenant
• API Response: Returns the expected "required scopes" error, confirming the endpoint exists and works

My company's Azure AD policies are pretty locked down. The tenant only allows self-consent to "low" risk permissions, and the only things classified as low are User.Read and email. All the permissions the Copilot API needs (Sites.Read.All, Mail.Read, Chat.Read, People.Read.All, ChannelMessage.Read.All, ExternalItem.Read.All) either aren't classified as low or require admin consent outright.

I also can't create app registrations in our tenant, so I'm stuck without getting IT involved.

Might be worth adding a note that enterprise users with restrictive consent policies will probably need their IT admin to either create an app registration with the required permissions, or grant admin consent for an existing app like Graph Explorer.

Anyway, the build fix should be good to merge. Someone with a less restrictive tenant or admin access should be able to pick up functional testing from there. Let me know if you need anything else.

Fantastic @tomstetson - Thank you. Great work! I'll review this and merge it with your fix. Also, the note about the enterprise users who might need their IT admin's help is a great idea.

[ksylvan]

@tomstetson The updated PR is here: #1936 - I'd love a quick sanity check please.

[ksylvan]

Thank you for catching that interface change. I also fixed a couple of Go "modernize" issues.
