The difference of group chat member roles. ("owner" vs "guest")

Question

The difference of group chat member roles. ("owner" vs "guest")

Hyeong-Ho Woo 20

Hi.

First, what I'm referring is NOT the difference of roles of team in MS Teams, but the difference of roles in group chats.

I created a group chat by calling this API:
POST https://graph.microsoft.com/v1.0/chats

And, I added two members. One has "owner" role and the other has "guest" role.

POST https://graph.microsoft.com/v1.0/chats/19:f70d4cf5a4b246f7831f6968f1259ab3@thread.v2/members

{
    "@odata.type": "#microsoft.graph.aadUserConversationMember",
    "******@odata.bind": "https://graph.microsoft.com/v1.0/users/7a0fb580-b658-4041-bf98-c3881cc6e1a1",
    "visibleHistoryStartDateTime": "2019-04-18T23:51:43.255Z",
    "roles": ["owner"]
}

{
    "@odata.type": "#microsoft.graph.aadUserConversationMember",
    "******@odata.bind": "https://graph.microsoft.com/v1.0/users/c79f94ea-9931-4db8-bb5a-1b2b07c43ad5",
    "visibleHistoryStartDateTime": "2019-04-18T23:51:43.255Z",
    "roles": ["guest"]
}

In my observations, two members seem to have same functionalities in MS Teams PC app, and I can't find any documents about the differences.

Can you explain what is the actual difference between "owner" role and "guest" role in group chats? (Again, I'm NOT referring the roles in teams or groups.)

Thanks.

Hello Hyeong-Ho Woo,

Thank you for reaching out to Microsoft Support!

According to the Graph API documentation, there are only two values for chat member roles: owner or guest. We need to provide this parameter only when creating chat or adding a member to chat. Depending on the user being added, we assign different roles. In terms of permissions, guest users do not have the permission to manage chat, that is, they cannot add, update, delete members and other operations.

Hi, thanks for your answer. But, I want to know more about this.

Are there any documents that have a more detailed list of chat permissions per role like this document : (the difference of roles of team in MS Teams) ?

Or is the link you attached to your answer the only document that describes about this?

Thanks.

There is no more detailed documentation to describe the list of permissions for chat roles. This is the only documentation that can describe this problem. in fact, similar to the difference of roles of team in MS Teams, the following permissions are not available for guest roles.

Thanks for your last comment.
So, It seems that I can think that users who has guest role don't have so-called 'management' functionalities in group chats.

I will accept your answer.
