Microsoft Teams AadSync Adding Team members from one team to another

Hello Daniel,

I am not sure if I would consider it as an error message but synchronizing or adding the team members on the 2nd team (let's call it Team B) and adding it on the first team (Team A) is indeed an error.

Attached is a screenshot of the updates found on the right side of your team in Microsoft teams. In one of your teams, click General. On the lower right-hand side, you should see "Updates". I've clicked on updates to show More Updates and this is where I saw all the activities (adding/removing team members) including the activities where Microsoft Team Aad Sync added the team members on Team B to Team A.

Thanks,

Cy

Hello Daniel,

Yes, I am able to remove the users successfully from Team A. I just did it in Microsft Teams through the "Manage Team" option. We've never used the Azure portal to manage the team members on Microsoft Teams.

I am sure you understand that the issue is that the team members on Team B should not have been added to Team A.

Have you encountered Aad Sync on Microsoft teams previously?

Thanks,

Cy

Hello Daniel,

May I ask what we are trying to test? Is it to test if adding team members to a team via Azure would cause it to sync to another team?

I can certainly try that, however as I mentioned previously, we never used Azure to add team members.

Thanks,

Cy

Hello Daniel,

Thank for clarifying.

Here's what I did. I created a 3rd team (Team C) and added team members there that are not on Team A and Team B. I did this via Azure. The team members on Team C were not added either to Team A or Team B.

What could have triggered the AadSync to add team members to another team? Looking around Azure, I saw Azure AD Connect and it says "not enabled", and "Sync has never run". See attached. I am not sure if that refers to Microsoft AadSync but it does sound like it.

Please let me know what our next steps are to have this investigated further.

Thanks,

Cyrus

Hello Daniel,

Team A is a closed team with sensitive information so I do not want to add team members there, as is the case with Team B. So what I did was created a 3rd team, team C and added team members there. Team members added on Team C did not sync to Team A or B.

Also when the issue happened it was when I created Team B and added team members there. The team members on Team B were then synced by AadSync to Team A, not the other way around.

Thanks,

Cy
