Active Directory Security group as Member in Teams group. Updates from AD Security group does not flow/sync into Teams Group

Question

When an Active Directory security group is added as a member to Teams group, it extracts the individual entities within the AD group as members to the Teams group. However if new members are added to the AD security group, it does not update / add those new members from AD group to the Teams group. Does Microsoft have anything in pipeline to allow for this functionality? i.e. get updates to Teams members based on the AD security group? If there is desire to have AD security group or groups as members of a Teams group, what is the recommended approach to accomplish this where constant updates are not necessary to get in changes from AD groups into Teams group? Thank you!

Hi @CoolCola-9184,

To me this may be the expected behavior.

When you add a group to a team in Teams client, it would add the current members to this team and would not update if there are changes in the membership of the group.

Here is also a thread discussing about the similar scenario: Adding a AD group to teams

And also documented here: Syncing Security Groups with team membership

If you add a security group to a team membership list, Teams will do a one-time expansion of the security group (same for a distribution list), but any subsequent changes are not reflected in the team, and vice versa.

If it is possible please consider using dynamic membership for Teams, or use scripts to sync the membership like mentioned in the link.
