How can I set the email for a Team with Microsoft Graph API?

Question

We are creating a team group (with the beta Graph API) and we want the emailaddress to contain another value than the value that's based on what's provided in displayName.

While searching through the documentation it seems that this is possible by providing a value for mailNickname in AdditionalData (https://learn.microsoft.com/en-us/graph/teams-create-group-and-team).

So I implemented that. Unfortunately the mailaddress and the alias were still like TestGroup@domain.nl instead of TestMailNickname@domain.nl.

var graphApiServiceClient = new GraphServiceClient(this.authenticationProvider)
{
    BaseUrl = "https://graph.microsoft.com/beta"
};

var owner = "valueForOwner";
var teamTemplate = teamTemplateType == TeamTemplateType.Staff
    ? "educationStaff"
    : "educationClass";

var team = new Team
{
    AdditionalData = new Dictionary<string, object>
    {
        { "template@odata.bind", $"https://graph.microsoft.com/beta/teamsTemplates('{teamTemplate}')" },
        { "owners@odata.bind", new[]{$"https://graph.microsoft.com/beta/users('{owner}')"}},
        { "displayName", "TestGroup" },
        { "description", "This is a testgroup" },
        { "mailNickname", "TestMailNickname" }
    }
};

await graphApiServiceClient.Teams.Request().AddAsync(team);

The MailNickname does change when I update the MailNickname property afterwards with an update request like await graphApiServiceClient.Groups[objectId].Request().UpdateAsync(new Group { MailNickname = mailNickname});.

This is confirmed with a graphApiServiceClient.Groups[objectId].Request().GetAsync()

Unfortunately it still shows TestGroup@domain.nl as the alias in the admin at https://admin.microsoft.com/AdminPortal/Home#/groups.

But, updating the value like this doesn't work for the Mail property because it states it's readonly in the update request.

Does anyone know what I am doing wrong in my original create/add request?

Plus does anyone know why the old alias value is still shown instead of the updated alias at https://admin.microsoft.com/AdminPortal/Home#/groups?

It looks like you are using an EDU tenant, since you are referencing the particular templates.

I have tested this previously, and the method suggested above will not work with the "EducationClass" template.

The way I got it to work was:

• Create the Team with the template

        $Teamdata = 
            '{
                "displayName":"' + $newteamName + '",
                "description":"' + $newteamName + '",
                "template@odata.bind": "https://graph.microsoft.com/v1.0/teamsTemplates(\u0027educationClass\u0027)",
                "hideFromOutlookClients":  "true",
                "hideFromAddressLists":  "true",
                        "members":[
                    {
                        "@odata.type":"#microsoft.graph.aadUserConversationMember",
                        "roles":[
                        "owner"
                        ],
                        "user@odata.bind":"'+ $DefaultOwnerURL + '"
                    }
                ]
            }'

• Wait for the group to be created (usually about 20 seconds)
• patch the group mailnickname

        $Body_SetGroupSDSSettings = 
            '{
                "mailNickname": "' + $newteamMailNickname + '"
                
            }'

It isn't perfect, but it is the best way I could find to do this.

This is possible by creating a group via the Graph api first and then using the group ID to create a team for this group.

Create the group via "https://graph.microsoft.com/v1.0/groups".

 {  
    "displayName": "TestGroup",  
    "mailNickname": "TestMailNickname",  
    "mailEnabled": true,  
    "securityEnabled": false,  
    "description": "This is a testgroup",  
    "groupTypes": [  
        "Unified"  
    ],  
    "owners@odata.bind": [  
        "https://graph.microsoft.com/v1.0/users/OWNEDID"  
    ]  
} 

Once the group has been made it'll output an ID which you'll then use to create a team via "https://graph.microsoft.com/v1.0/groups/YOURIDHERE/team"

Body would look something like;

{  
    "memberSettings": {  
        "allowCreateUpdateChannels": false,
        "allowAddRemoveApps": false,
        "allowCreateUpdateRemoveTabs": false,
        "allowCreateUpdateRemoveConnectors": false  
    }
}
