I'm using the next endpoint for getting "https://graph.microsoft.com/v1.0/users/?$select=id, displayName, mail, userPrincipalName" According to docs: https://docs.microsoft.com/en-us/graph/api/resources/user?view=graph-rest-1.0 there is no any info about unique mail property for user resource type.

mail String The SMTP address for the user, for example, "[email protected]". Supports $filter.

Question: is it possible to get two or more users (with different ids) and the same mail property?

The User mail property should be unique.

You will get the following error message when you try to create a new user with the same mail property.

"error": {
        "code": "Request_BadRequest",
        "message": "Another object with the same value for property proxyAddresses already exists.",
