I am encountering an issue with an Outlook add-in that I have developed. The specific office js error message is "API is not supported in this platform," and it occurs when attempting to execute the OfficeRuntime.auth.getAccessToken({allowSignInPrompt: true, forMSGraphAccess: true}); method to get the access token.
Here are some details:
- Outlook Version: Microsoft 365 MSO, Version 2311 Build 16.0.17029.20028
- Platform: 64-bit
- API Compatibility:
isSetSupported('IdentityAPI', '1.3')returns true
Any insights or guidance you can provide would be greatly appreciated.

2024-01-03T04:37:33.15+00:00 We can't use
forMSGraphAccessauth option in thegetAccessTokenmethod for development or test deployments. It will always return the 13012 error for SSO. When I remove theforMSGraphAccessoption from the test deployments and also when developing the add-in the issue is fixed.Followings are the related troubleshoot documentations.
