Unable to add members to a Team from a security group (dynamic membership)

[WMarkus]

Hello,

A security group with a dynamic membership rule is utilized to add guest users to an existing Microsoft Teams team. However, only one member is visible, and attempting to proceed yields an error. Has this issue been encountered by others?

The Entra ID security group contains 19 guest accounts. The individual attempting to add the group is the Team owner. The new Teams client is being used, and the issue persists even when attempting via the web.

Thanks!

Hello,
I guess you meant Microsoft 365 dynamic Group?
I was able to use the functionality, it took a while.

Hello @AndresGorzelany,

It is a security group with type: Dynamic. Using a dynamic membership rule, we add all guest accounts from a specific supplier. The group can be selected when adding members (MS Teams), but only one (random) guest account appears in the screen where you can also adjust the membership. Additionally, I cannot remove the guest account using the cross (X) button.

Ok I think I identified the issue

Adding the security group that way actually expands the members of the security group and tries to add them as members of the team, however, that dialog does not add them as guest user type but tries to add them as members, failing

Even if it would work, you would have to run that dialog regularly, as it won't update when new members are added to the group.

I guess this team has members of the company and it is also intended to have guests, right? is it a new team? Maybe you can create a Microsoft 365 Group dynamic with rules that include both the guests and the members of the tenant

Please let me know if I understood correctly

I am aware that the group needs to be re-added if new members are added. It is a new Team. I get the same message when I use a security group that only contains internal members.

Microsoft Support is currently investigating the HAR logs.
