I would like to get all user contact email in Azure DevOps.

First, I tried to use https://vssps.dev.azure.com/{{organization}}/_apis/graph/users API to get all users. I can see all of user info, but the mailAddress for each user is not the contact email address for each user.

Then I tried to use https://app.vssps.visualstudio.com/_apis/profile/profiles/me to get my user profile. It did return correct info including my contact email in emailAddress attribute

But when I tried to use https://app.vssps.visualstudio.com/_apis/profile/profiles to get all user info, I get error

{
    "count": 1,
    "value": {
        "Message": "The requested resource does not support http method 'GET'."
    }
}

I couldn’t find any documents to indicate how I can get all user profile, including contact email from Azure API service. Does anyone have any clue for the solution?

Thanks
