getUserInfo REST API response with 401 by using scope "openid profile email wl.imap wl.emails wl.offline_access"

Question

I am developing a Android Mobile Email App to connect outlook imap/smtp server by Oauth2 to pull/send Email by outlook account.
I can get AccessToken/Refresh Token by using AppAuth with SCOPE "openid profile email", and I can get user info by getUserInfo(oidc/userinfo) REST API with AccessToken(with scope "openid profile email").
But when I use SCOPE "*openid profile email https://outlook.office.com/IMAP.AccessAsUser.All https://outlook.office.com/SMTP.Send*", the REST API of getUserInfo(oidc/userinfo) failed and get response code 401.
I don't know why, cloud you help me to fix this issue.

when using scope "wl.imap wl.emails wl.offline_access", I can connect imap/smtp server, but also can not get user info by REST API of getUserInfo(oidc/userinfo). It is also response with 401 error.
when using scope "openid profile email wl.imap wl.emails wl.offline_access" , still can not get user info, also response with 401 error.

401

{"error":{"code":"InvalidAuthenticationToken","message":"CompactToken parsing failed with error code: 8004920A","innerError":{"date":"2022-01-19T08:04:30","request-id":"aef5eef3-4bc2-41be-86c8-be7a5362b4e8","client-request-id":"aef5eef3-4bc2-41be-86c8-be7a5362b4e8"}}}

Hi @Xie Nash

You are getting outlook token not Graph token, to call the oidc/userinfo endpoint you should remove the scope: https://outlook.office.com/IMAP.AccessAsUser.All, https://outlook.office.com/SMTP.Send.

ie: "scope": "openid profile email User.Read" .

Another method is keeping your current scopes and call GET https://outlook.office365.com/api/v2.0/me/ to get the signed-in user's information.
