Provide required information needed to triage your issue

Your Environment

• Platform [PC desktop, Mac, iOS, Office on the web]: Office
• Host [Excel, Word, PowerPoint, etc.]: Outlook
• Office version number: NA
• Operating System: NA
• Browser (if using Office on the web): Firefox

Current behavior

We developed and implemented the SSO authentication in our Office outlook add-in. But we have some issues in the Firefox browser.

In chrome, edge or even the new outlook application, the SSO works correctly, but when I try to authenticate with the SSO in Firefox I either que and Error 13006 or 13001 and the SSO never works... I checked into the docs at https://learn.microsoft.com/en-us/office/dev/add-ins/develop/troubleshoot-sso-in-office-add-ins but even when I tried to sign out and then sign back I get the same error... I also tried emptying the Firefox browser cache to no avail.

The error is thrown when executing the OfficeRuntime.auth.getAccessToken({ allowSignInPrompt: true }); also tried removing all the parameters to use just OfficeRuntime.auth.getAccessToken() But it didn't work either

Steps to reproduce

1. Install our xml at https://office365.secure-exchanges.com/SecureExchanges.xml our any valid manifest with an SSO configured
2. Open side panel on message compose or read
3. Click the "activate license" button so that the SSO tries and then you should get the error if it fails. Or simply try to run the getAccessToken function.

Useful logs

• Console errors: Object { name: "No user is signed into Office.", message: "No user is signed into Office.", code: 13001 }

@mattgeim Can you take a look?

@SE-Hubert Did you note this line from the article that you linked to?

"... if a user accesses Outlook on the web from Firefox with Enhanced Tracking Protection turned on, they'll encounter error 13001."

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

Solution 1:

Disabling 'Prevent cross-site tracking' in the Safari preferences and restarting the browser does allow the request to work but this isn't a viable option for a public add-in.

Solution 2:

OfficeRuntime.auth.getAccessToken and Office.context.auth.getAccessTokenAsync both seem to rely on third party cookies, probably a cookie from login.microsoftonline.com.

I though I tested it, but look like I was wrong. By disabling the tracking protection it works fine thank you !
